Replacement Carrier Shim Kit for Dana 70 & 70HD differentials

What this shim kit is for

A carrier shim kit is one of those “small parts, big impact” items—because shims affect how the differential carrier sits and how the gears contact under load. This replacement carrier shim kit is made to fit Dana Spicer 70 and 70HD applications, so it’s aimed at repairs where you need to restore the correct setup rather than improvise.

On paper, the value is pretty straightforward: if your goal is to get the Dana 70/70HD back into spec after disassembly, having the right shim kit matters. If you’re chasing a noisy differential, vibration, or pattern concerns that point to setup/clearance issues, a proper replacement shim kit can be the difference between “it’s close” and “it’s right.” That said, this listing doesn’t include measurements, shim sizes, or thicknesses, so you’ll still want to verify what your specific job requires before assuming everything will match perfectly.

Key takeaways before you buy

This is a replacement shim kit intended for carrier setup on Dana Spicer 70 and 70HD. In a lot of DIY and shop scenarios, it’s purchased because: - You’re doing a rebuild and the old shims aren’t usable anymore. - You’re replacing components and need to re-establish proper positioning. - You want replacement parts that are meant for the correct Dana family, rather than mixing random parts.

Where it may fall short is also important: without details on included shim thickness options or exact contents, it can be harder to judge up front whether it covers your exact correction needs. If your build requires very specific adjustment, you may need to cross-check what you already have on hand and what your teardown reveals.

What to notice during installation

The practical “feel” of this kind of part is that it’s not a bolt-on for performance—it’s a setup piece. Expect the process to be focused on correct carrier positioning rather than quick assembly.

For a real-world example: imagine you’ve replaced bearings or reinstalled the carrier after cleaning everything up. Before final tightening, you swap in the carrier shims, check gear contact/pattern, and confirm clearances. If the pattern is off, you adjust shim thickness and repeat the checks. A replacement shim kit fits into that loop.

Does this mean it fixes every symptom automatically? No. If the underlying issue is something else—like damaged gears, worn bearings, or an assembly mistake—shims alone won’t save it. Still, for alignment/positioning problems that come from rebuild work, the kit is exactly the kind of part you reach for.

Who it’s a good fit for

It makes sense if you’re working on a Dana Spicer 70 or 70HD carrier setup and you need a replacement shim kit during service.

You’ll likely appreciate it more if: - You’re doing a rebuild or carrier reassembly and want to use purpose-matched replacement shims. - You prefer handling the setup properly (checking gear contact and clearances) instead of guessing.

It’s less ideal if you’re looking for a general-purpose repair kit for multiple axle types. The listing is specific to Dana Spicer 70 and 70HD, so compatibility outside that scope is not something you should assume.

Maintenance and handling tips

Shims are small, but you don’t treat them casually. Keep them clean and dry, avoid scratching mating surfaces, and handle them so they don’t pick up debris. Also, it helps to keep your old shims organized during teardown—because even when you replace them, they can inform what correction range you’re dealing with.

Mini FAQ

Is this kit only for Dana 70 and Dana 70HD?

Based on the description, yes—it’s intended to fit Dana Spicer 70 and 70HD. If your application is different, you should not assume it will work.

Do I need this for a full differential rebuild?

If your rebuild involves carrier disassembly and reassembly, shims are typically part of setting up carrier position and gear contact. If you’re only doing unrelated repairs, you may not need them.

What if my symptoms are noise or vibration?

Shims can help when setup/positioning is the cause after work has been done. If the issue is worn components, damage, or bearing problems, you’ll want to address the root cause—not just the shim stack.

Should a shop or DIY use it?

Both can, but the key is proper setup. If you don’t have a process for checking gear contact and clearances, a shim kit won’t be as effective.

Is it worth it?

If you’re repairing or rebuilding a Dana Spicer 70 or 70HD and need a replacement carrier shim kit, this is the kind of part that’s easy to underestimate but useful when you’re doing setup correctly. Buy it when you’re at the stage where shims are part of getting the carrier positioned and gear contact dialed back in.

You may want to skip it if you don’t know your exact shim needs yet, or if your problem isn’t tied to carrier positioning after teardown. And keep in mind the limitation here: the listing doesn’t provide shim contents or thickness options, so you’ll want to verify what’s included relative to what your repair requires.

Overall, it’s a targeted replacement part for Dana 70/70HD work—worth it for the right job, but not something to treat like a universal fix.
