What We Found

Moser Engineering’s A3070GMT2 is listed as forged steel street axles for GM 2wd truck 12-bolt applications with 30-spline interfaces. The listing highlights non-tapered construction and hardened, ground bearing seats, which points to more consistent fit and potentially better longevity at the bearing interface.

It also calls out machined C-clip grooves, which can help with axle retention and assembly alignment. Those machining details put it beyond basic replacement into a more durability-oriented category for driveline reliability. The listing also frames the axles as suitable for stock OEM application, which can help avoid setup surprises.

Package quantity is listed as 1, so I would verify whether that means a single axle unless the listing elsewhere clarifies it is a set.

Who It’s For

I would pick this for GM 2wd truck owners using a 12-bolt rear end who need 30-spline axles. It fits street-driven builds that see daily wear, towing, or frequent gear changes. The hardened and ground bearing seats are especially relevant if you care about predictable end-play and bearing life.

The forged steel design also appeals if you want durability from the axle replacement without changing other rear-end hardware. Just confirm whether you need a pair, since quantity appears to list 1 unit.

Part Number	A102601CT-1
Axle Length	28-7/16 in
Spline Count	26 spline
Bolt Pattern	5 x 4.75 in

What We Found

Moser Engineering’s Axle Shaft A102601CT-1 is built around a direct-fit approach for GM 10-bolt C-clip setups. The listing calls out 28-7/16 inch length, a 26-spline carrier, and a 5 x 4.75 bolt pattern, which helps narrow compatibility.

It also shows a steel axle shaft with a natural finish, and the included components are listed as a kit. Although it says universal fit type, the part numbering and GM 10-bolt G-body context feel more application-specific than broad “fit anything” language.

Overall, my read is that it’s a clean configuration match when your build already lines up with those specs.

Who It’s For

I would shortlist this for G-body 1978-81 builds running a GM 10-bolt C-clip rear end that uses a 26-spline carrier. It fits best when your axle length and spline count already match the parts list, because that reduces return risk.

If you are planning wheel and hub selection around a 5 x 4.75 pattern, the listing details help you stay aligned. This is more about correct assembly than custom fabrication.

Part Number	A102804
Axle Length	30-5/16 in

Knurl Diameter	.505 in

What We Found

Moser Engineering’s A102804 is positioned as a C-clip replacement axle for a 28-spline application, with a stated .505 inch knurl. The listing text includes a 30-5/16 inch length and 28-spline gearing match, plus a bearing and seals pairing reference of 718-9563.

It also includes compatibility notes for 1982-92 Camaro and Trans Am applications, which helps avoid broad mismatches. The knurl dimension is another useful detail, because axle interface features can affect how the assembly fits during install.

For buyers restoring common F-body setups, it reads like a practical axle-side replacement with clearer interface guidance than many generic listings.

Who It’s For

I would shortlist A102804 for 1982-92 Camaro and Trans Am owners who have the specified C-clip rear-end configuration with 28-spline axles. It fits street-driven restorations and weekend projects where the goal is driveline smoothness without switching to a different axle system.

The .505 knurl and the 718-9563 pairing reference are helpful for DIY installers who want to keep supporting parts aligned. It also works for shops doing repeatable repairs on second-generation F-bodies.

Bearing Type	Axle bearing
Bearing OD	3.150 in
Bearing ID	1.531 in
Applications	Ford 8.75, 9, 9.5, 9.75 and Oldsmobile/Pontiac

What We Found

This Moser Engineering axle bearing listing is aimed at Big Ford and Oldsmobile/Pontiac rear-end families, and it leans on dimension-driven compatibility. It states bearing OD of 3.150 inches and bearing ID of 1.531 inches, which is useful because you can validate fit against a worn bearing without guessing.

The listing names applications including Ford 8.75, 9, 9.5, and 9.75, which covers several common “big Ford” rear ends. It also includes Oldsmobile/Pontiac compatibility, so it is not limited to one platform family.

The text mentions “each applications,” but it does not provide a clear quantity detail beyond that phrasing, so buyers should confirm whether they need one bearing or a pair. As a standalone bearing replacement, it supports rebuilds focused on restoring smoothness and reducing driveline play.

Who It’s For

I would pick this bearing when you have Big Ford-style or Oldsmobile/Pontiac rear ends and you need a replacement bearing that matches the given OD and ID. It works well when the axle shafts are still in good shape, but the bearing wear is causing noise or looseness.

The Ford application range is helpful if you work across multiple rear-end variants in similar projects. It also suits shops that prefer matching bearings by measurements instead of relying only on axle length or loose “fits” language. Just confirm quantity needs and seal mating surfaces before installing.

Part Number	A123002
Axle Length	29-1/2 in
Spline Count	30 spline
Bolt Configuration	12 bolt GM

What We Found

The Moser Engineering axle option referenced as A123002 is presented as a 29-1/2 inch C-clip axle configuration with 12-bolt and 30-spline specifications. That combination narrows it to a specific driveline family, because axle length and clip geometry directly affect end-play and assembly alignment.

The listing also confirms U.S. country of origin and includes package dimensions, which supports that this is a packaged axle-side part. Package quantity is listed as 1, so the order may be for a single axle depending on your checkout needs.

The key advantage is that the title-level details spell out length, 12-bolt, and 30-spline, so you do not have to guess your way into compatibility.

Who It’s For

I would select this when you have a GM C-clip rear end with a 12-bolt housing and a 30-spline setup that needs a 29-1/2 inch axle. It is useful when one side fails, or when a project demands precise length matching.

It also fits installers and restorers who prefer part specs that map directly to a known build configuration. Because quantity is listed as 1, I would confirm whether you need one axle or both to finish the job efficiently.

Part Number	A2867MUST
Application	67-70 Mustang
Rear End	w/9in
Spline Count	28-spl

What We Found

Moser Engineering’s A2867MUST C/A axle set is aimed at 67-70 Mustang applications with a 9-inch rear end and a 28-spline setup. The title includes the fitment window, which makes it easier to confirm whether it lines up with your classic Mustang build.

Package quantity is listed as 1, so I would double-check what that means for set contents before ordering. The dimensions suggest a long, heavy assembly consistent with axle installation.

Unlike listings that only state spline count, this one also names the rear end type, and that matters because bearing-seat geometry and axle length requirements often change by rear end family. My read is that it is meant to be street-ready strength within the correct 9-inch C/A axle framework.

Who It’s For

I would choose this for 1967-1970 Mustang builds that use a Ford 9-inch rear end and need 28-spline axles. It is a good fit for restorations that want updated axle components while staying compatible with the intended rear-end interface.

The “street” framing suggests it should suit daily driving and mild performance use. Before buying, I would confirm your rear-end C/A interface matches, and I would verify set contents because the quantity label alone can be confusing.

Part Number	9400RP
Application	Mopar 8-3/4
Bearing Style	Green press-in style
OEM Equivalent	9400RP

What We Found

The Moser Engineering 9400RP is a press-in style axle bearing aimed at Mopar 8-3/4 use. The listing includes the part number 9400RP and provides packaging weight of 3.159 kilograms, which suggests a dedicated bearing shipment.

While there are no internal dimensional specs in the provided text, the press-in style matters because seating and alignment affect how the bearing rides. The listing also includes an OEM-equivalent part number, which helps with cross-checking against existing Mopar documentation.

Since this is bearing-only, it makes the most sense when the axle shaft itself is still usable. My read is that it is a narrow part, but it is purposeful for that maintenance job.

Who It’s For

I would buy this if you are restoring a Mopar 8-3/4 rear end and you specifically need a press-in bearing that matches the 9400RP reference. It is a good fit when the axle interface looks fine, and the wear is mainly at the bearing seating area.

This also suits shops doing routine rear-end refresh work, where correct bearing seating is what keeps noise down. If your plan is only to replace the bearing interface, it should be the more efficient purchase than an axle kit.

Part Number	A102812-1
Spline Count	28 spline
Carrier Type	10 bolt GM rear end
Country Of Origin	United States

What We Found

Moser Engineering’s A102812-1 is listed for a 10-bolt GM rear end with 28-spline specifications. The listing also notes it is made in the United States, which supports confidence in consistent manufacturing for a precision driveline part.

Package dimensions and weight are provided, which signals this is a substantial axle assembly shipment. In the text provided, the listing content emphasizes spline count and rear-end family, but it does not clearly state axle length or C-clip style.

That means correct install depends on confirming axle length against your rear end setup. Still, the 28-spline 10-bolt GM focus narrows the compatibility more than a generic offering.

Who It’s For

I would use A102812-1 for GM 10-bolt rear ends that require 28-spline carrier interfaces. It makes sense for restorations and street builds when the axle length matches what your specific rear end setup calls for. The made-in-USA note is a nice reassurance for machining consistency.

Before you order, I would measure or cross-check axle length, because that is the missing piece in the provided details.

Part Type	Axle bearing
Brand	Moser Engineering
Compatibility	Ford stock ID
Role	Quality replacement part

What We Found

This Moser Engineering axle bearing is described for Ford stock ID compatibility, but the provided listing details are limited. It states it is compatible with Ford and that it matches a stock ID, yet it does not include the OD, ID, or the specific rear-end family in the text shown.

Without those dimensions, buyers have to rely on existing part numbers or measure the bearing they are replacing. The listing still signals replacement-part intent from Moser, but dimension clarity is what usually prevents wrong-bearing orders. Because axle bearings impact driveline smoothness and bearing life, ambiguity can raise return risk.

If you already know the exact Ford stock ID required, this can be a straightforward replacement.

Who It’s For

I would consider this if your Ford rear-end setup already has a confirmed stock ID requirement for the bearing. It fits best when you have identified the bearing to replace, and measurement can verify the ID.

It also suits DIY installers who are comfortable validating fit with measurements instead of trusting title-only compatibility. The downside is the lack of OD and ID values in the provided text, which can make quick ordering riskier for first-time buyers.

Part Number	812TK
T-Bolt Size	1/2 in
Included Component	Housing end
Package Type	Kit

What We Found

The Moser Engineering 812TK is a 1/2 inch T-bolt kit with a housing end, so it is not an axle shaft or axle bearing component. The listing focuses on retention hardware for systems where T-bolts matter, and it includes the housing end.

Package quantity is listed as 1, and the provided package weight of 0.539 kg suggests a compact hardware bundle. Even though the article is about axles, this reads as an accessory for related builds rather than something that replaces axle parts.

If you are considering it, I would treat it like a compatibility-dependent add-on, since the text does not define any rear-end, spline, or axle length fitment. T-bolt kits can help secure joints and maintain alignment, which can matter for vibration control and leak prevention in systems that use T-bolts.

Who It’s For

I would buy this when you need replacement or supplementary 1/2 inch T-bolt hardware with a housing end for a related assembly. It works best for installers doing maintenance where axle-adjacent joints need secure mounting.

Because the listing is hardware-specific, it suits projects with known T-bolt specs more than general fabrication. It also fits shops that like OEM-like hardware bundles to keep install steps straightforward.

Since it is not tied to a rear-end or axle spec in the listing text, I would verify compatibility against your existing parts before ordering.

What to Look For Before Buying

For Moser Engineering axles, I would start with your rear end and retention style, then confirm spline count and axle length. If you are replacing bearings, matching OD and ID matters just as much.

Finally, I would double-check whether the listing is for one axle, a pair, or a full set.

Check Match rear end, axle retention, and spline count

Start with your rear-end model and whether it uses C-clips. Then verify the spline count for your carrier and differential. Make sure the axle interface lines up with your bearing seat style. This is what prevents end-play surprises after installation.

Value Pick the right scope: axle shaft versus bearing-only

Figure out whether you need new axle shafts or only bearings. Bearing-only parts work best when axle splines and grooves are still within spec. Axle sets make more sense when length or spline count needs to change. I would avoid buying full axles if only seating wear is the issue.

Rating Use listing detail quality as an accuracy signal

When ratings are missing, I focus on listing specs like axle length, spline count, and bearing OD and ID. Clear part numbers often signal better compatibility. If the listing mentions hardened and ground bearing seats, that is another good machining clue. Details like these usually mean fewer fitment issues.

Verify Confirm quantity and required supporting parts

Check quantity carefully, because some listings are for one axle while others cover a full set. If bearings and seals are referenced, review that guidance before checkout. Look for knurl and C-clip groove details when those are provided, since they affect assembly.

Then plan for your tools and any press steps before you start.

Frequently Asked Questions

How can spline count differences cause installation problems?

Spline count determines how the axle engages the carrier side gear. If the spline count does not match, the axle will not seat correctly, and it can damage mating surfaces. That can show up as poor end-play and driveline noise after assembly.

What should be verified for C-clip axle replacements?

For a C-clip axle replacement, I would verify axle length, C-clip groove geometry, and spline count for your exact rear end. A groove mismatch can affect retention and the correct end-play position. Also confirm whether you need one axle or a pair based on the package quantity.

Are press-in axle bearings interchangeable across rear ends?

Press-in axle bearings usually vary by OD, ID, and how they seat in the housing. Even when a listing says press-in style, I would still verify the measurements. Matching OD and ID to your axle and housing seats reduces ordering mistakes.

Do forged steel axles always ride better or last longer?

Forged steel often improves strength and fatigue resistance, which can help service life under load. Ride comfort depends more on bearing condition, installation quality, and overall driveline balance. You usually feel smoother operation when the bearing seats mate correctly.

Why does axle length matter as much as spline count?

Axle length affects how far the axle seats into the bearing, and it changes where the C-clips sit inside the carrier. If length is wrong, end-play can be off, which can cause binding or faster wear. Length verification also helps prevent seal damage from misalignment.

🎯 Final Verdict

My top pick is A102601CT-1, because it matches a 28-7/16 inch axle length with a 26-spline GM 10-bolt C-clip setup and a 5 x 4.75 bolt pattern.

If you want forged steel plus hardened, ground bearing seats for durability, I would consider A3070GMT2 for the GM 2wd truck 12-bolt 30-spline application. In either case, confirm spline count and retention style first, then verify axle length before ordering.
