Yukon Gear & Axle Differential Carrier Shim Kit

Precision Shimming from a Drivetrain Specialist

When rebuilding or upgrading a differential, few steps are more critical — or more commonly underestimated — than achieving proper carrier bearing preload and ring gear backlash. Getting that setup wrong means accelerated wear, noise, and premature failure. That's where Yukon Gear & Axle earns its reputation: the brand brings the same engineering discipline it applies to ring & pinion sets and lockers straight into its line of Differential Carrier Shim Kits.

Application-Specific Engineering

One of the most common frustrations during a differential rebuild is discovering that generic shims don't fit correctly for a specific axle housing. Yukon addresses this directly: Yukon shim kits are precision machined and tailored for each individual application to ensure you have the right shims for every set up. Rather than offering one-size-fits-most packs, Yukon maps its shim kits to specific axle families, so builders know exactly what they're getting before the diff is ever opened.

The breadth of platform coverage is a standout strength. Yukon offers carrier shim kits across a wide range of popular axles, including:

• Dana 30, 44, 44HD, 50, 60, 61, and 70-U — covering Jeep, Ford, and GM truck applications
• Ford 9.75" — the Super Carrier Shim Kit (SK SSF9.75) targets this popular late-model Ford axle
• AMC Model 35 — the SK SSM35 Super Carrier Shim Kit is purpose-built for this common Jeep rear differential
• Toyota 8.75" — available in both left-hand (SKT8.75LH-CSK) and right-hand (SKT8.75RH-CSK) rear configurations
• GM 8.5", 8.6", and 10-bolt platforms — among the most widely rebuilt differentials on domestic trucks and SUVs

Two Kit Styles: Standard Replacement & Super Carrier

Yukon's carrier shim lineup comes in two primary formats to suit different build scenarios. Replacement Carrier Shim Kits (such as the SK 702005 for Dana 44HD and the SK 706375 for Dana 60/61/70-U) deliver the correct shim assortment to restore factory-spec carrier positioning during a rebuild or gear swap. Super Carrier Shim Kits — designated with the "SSM" or "SSF" prefix — are designed for builders who want an expanded range of shim thicknesses, giving greater flexibility when dialing in backlash and preload on an upgraded or heavily modified axle.

Built to Exceed OEM Standards

Yukon Gear & Axle was founded on the premise that superior materials, advanced manufacturing techniques, and obsessive quality control will produce unrivaled performance. That philosophy carries directly into its shim kits. Whether installing a new ring & pinion, locker, LSD/posi, or just giving a differential new bearings and seals, Yukon's quality parts meet and often exceed OEM standards for quality, performance, and durability.

Yukon's in-house engineering group utilizes state-of-the-art software to design products that are then manufactured in partnership with some of the world's foremost leaders in OEM manufacturing. The result is a shim kit that holds tight tolerances — critical when a few thousandths of an inch can be the difference between a quiet, long-lived differential and one headed back to the bench.

The Right Kit for Your Build

Whether you're a professional shop swapping gears on a customer's daily driver or an off-road enthusiast upgrading to a locker, Yukon products are engineered for strength, precision fitment, and long-lasting performance on and off the trail. Paired with Yukon's broader ecosystem of ring & pinion sets, overhaul kits, and install hardware, a Yukon carrier shim kit ensures every dimension of the differential setup is accounted for from the start.
