Yukon Gear Carrier Shim Kit for Dana 60, 70, 70HD, 70U and Dana 80 Differentials
The SK 30276 from Yukon Gear and Axle is a carrier shim kit engineered for the heavy-duty Dana 60, Dana 70, Dana 70HD, Dana 70U, and Dana 80 differentials used in Chevrolet, GMC, Dodge, Ford, and Plymouth heavy-duty trucks and vans from 1960 to 2014. Part number SK 30276 provides the assorted carrier shim thicknesses necessary to correctly set carrier bearing preload and ring-gear backlash during gear installation or bearing service. Having SK 30276 on hand covers the complete lineup of Dana heavy-axle differentials commonly found in 3/4-ton and 1-ton vehicles, reducing the need to source multiple separate shim sets when working across different platforms.

Frequently Asked Questions
Q: What differentials does the SK 30276 fit?
A: The SK 30276 covers the Dana 60, Dana 70, Dana 70HD, Dana 70U, and Dana 80 differentials used in heavy-duty trucks and vans from 1960 to 2014.
Q: Does SK 30276 work for my Ford F-350 with a Dana 80?
A: Yes. The SK 30276 includes shims compatible with the Dana 80 rear axle used in Ford F-350 and F-450 Super Duty applications.
Q: Is this kit suitable for Dodge Ram 3500 applications?
A: Yes. The SK 30276 covers Dana 70 and Dana 80 rear axles used in Dodge Ram 3500 heavy-duty trucks across multiple model years.
Q: How does correct carrier shim selection affect differential performance?
A: Carrier shims control the lateral position of the ring gear, directly setting backlash and preload. Incorrect shim selection leads to noise, excessive wear, and shortened differential life.
Q: Can SK 30276 be used for both new gear installs and bearing replacements?
A: Yes. The SK 30276 is appropriate for any service requiring carrier shim adjustment in the covered Dana differentials, including new ring-and-pinion installations and carrier bearing replacements.
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 Yukon Gear parts does not void your vehicle's factory warranty when correctly installed.
Q: Is the SK 30276 compatible with Chevrolet and GMC heavy-duty trucks?
A: Yes. The SK 30276 is compatible with Dana 60 rear axles used in Chevrolet and GMC C/K 2500 and C/K 3500 trucks and Suburbans.
Q: Is professional installation recommended?
A: Yes. Carrier shim setting requires precision tools including a dial indicator and torque wrench. Professional installation ensures accurate differential setup and long-term reliability.
Installation Instructions
- Drain the differential and remove the cover. Mark the carrier bearing caps for correct reassembly orientation.
- Remove the carrier bearing caps and carefully extract the ring-gear carrier from the housing.
- Remove the existing carrier shims from both sides of the carrier bearing journals.
- Reinstall the carrier without shims and use a dial indicator to measure available lateral play, then calculate required shim thickness for each side.
- Select the appropriate shims from the SK 30276 kit to achieve the specified carrier bearing preload and ring-gear backlash.
- Install the selected shims, reinstall the carrier, and torque bearing caps hand-tight.
- Verify ring-gear backlash at 3-4 points around the gear with a dial indicator and adjust shim thickness as needed.
- Verify the gear tooth contact pattern with marking compound, then torque bearing caps to the manufacturer's specification.
- Reinstall the differential cover with a new gasket or RTV sealant and fill to the correct fluid level.
- Road-test the vehicle and check for leaks before returning to service.
