Yukon Gear Super Carrier Shim Kit for the GM 9.5in Differential
The SK SSGM9.5 from Yukon Gear and Axle is a Super Carrier Shim Kit built specifically for the GM 9.5in differential found in Chevrolet and GMC C/K 2500 and K2500 heavy-duty trucks, Suburbans, G-series vans, and V-series trucks from 1979 through 2000. Part number SK SSGM9.5 provides the expanded range of shim thicknesses needed to precisely set carrier bearing preload and achieve correct backlash during ring-and-pinion installation. The SK SSGM9.5 super kit is engineered to give the technician enough shim selection to handle variations in housing tolerances and new versus reused bearings, reducing the need for multiple trips to source additional shims.

Frequently Asked Questions
Q: What differential does the SK SSGM9.5 fit?
A: The SK SSGM9.5 is designed exclusively for the GM 9.5in differential found in 1979-2000 Chevrolet and GMC heavy-duty trucks, Suburbans, G-vans, and V-series trucks.
Q: What is a Super Carrier Shim Kit?
A: A super kit contains an expanded range of shim thicknesses compared to a standard carrier shim kit. The broader selection allows the technician to precisely set carrier bearing preload and ring-gear backlash across a wider range of housing and bearing tolerances.
Q: Why is carrier bearing preload important?
A: Correct carrier bearing preload minimizes carrier movement under load, which maintains consistent ring-gear backlash, reduces differential noise, and extends gear and bearing life.
Q: Does the SK SSGM9.5 work with my 1989 GMC K2500?
A: Yes. The SK SSGM9.5 is compatible with 1979-2000 GMC K2500 trucks equipped with the GM 9.5in differential.
Q: Is this kit compatible with Chevrolet Suburban models?
A: Yes. The SK SSGM9.5 fits the GM 9.5in differential used in 1979-2000 Chevrolet and GMC C2500 and K2500 Suburban models.
Q: Does this product come with a warranty?
A: Yes. Yukon Gear products are backed by a limited warranty. Under the Magnuson-Moss Warranty Act, using warranted parts does not void your vehicle's factory warranty when installed correctly.
Q: Can I use this kit with a Yukon Gear ring-and-pinion set?
A: Yes. The SK SSGM9.5 is designed to complement Yukon Gear ring-and-pinion installations in the GM 9.5in differential, providing the shim selection needed to meet gear setup specifications.
Q: Is professional installation required?
A: Carrier shim setting requires precision measurement tools including a dial indicator to verify backlash. Professional installation is strongly recommended for accurate differential setup.
Installation Instructions
- Drain the differential and remove the cover. Mark the carrier bearing caps for correct reinstallation.
- Remove the carrier bearing caps and carefully lift out the ring-gear carrier.
- Remove the existing carrier shims from both sides of the carrier bearing bores.
- Measure the required total shim thickness on each side using a dial indicator and preload gauge to achieve the specified carrier bearing preload.
- Select appropriate shims from the SK SSGM9.5 kit for each side.
- Install the selected shims and reinstall the carrier into the housing.
- Install the bearing caps hand-tight, then verify ring-gear backlash with a dial indicator at multiple points around the ring gear.
- Adjust shim thickness as needed to bring backlash within specification.
- Verify the tooth contact pattern with gear marking compound, then torque bearing caps to specification.
- Reinstall the differential cover with a new gasket or RTV sealant, fill to the correct fluid level, and road-test before returning to service.

Differential Install Kits
Differential install kits supply all the hardware required to correctly set up a new ring-and-pinion gear set during a re-gear, including pinion bearings, carrier shims, pinion seal, crush sleeve, marking compound, and ring gear bolts. Buying a matched install kit ensures proper gear mesh, preload, and backlash settings that are critical to differential longevity and noise-free operation.Popular Differential Install Kit ApplicationsInstall kits are available for nearly every popular axle including Dana 30, Dana 44, Dana 60, GM 7.5-inch, GM 8.5-inch, GM 10.5-inch, Ford 8.8-inch, Ford 9-inch, and Chrysler 8.25-inch and 9.25-inch differentials. Yukon Gear, Motive Gear, and Richmond Gear are common brands trusted by professional builders for accurate preload specs.Do I need a master install kit or a standard install kit?A standard install kit covers the basic bearings, seal, shims, and hardware needed for most re-gears. A master install kit adds carrier bearings and races, making it the...
