Buying Guide
How do you choose the right kit?
Start with the differential, not just the vehicle model. Compare the axle family and size in the product description with the differential installed in the vehicle. A Ford 8.8-inch kit, for example, is not interchangeable by assumption with a GM 8.2-inch kit. When axle details are uncertain, verify them with reliable vehicle or differential documentation before buying.
Do shim options matter?
Shim availability matters when the setup process requires selecting a shim thickness. Two kits in this list specifically mention a wide variety of shim thicknesses: the GM 7.5/8.2 differential kit and the GM 12-bolt truck kit. The supplied descriptions do not give exact thickness ranges, so check the product details or consult a qualified installer if a particular size is required.
What should you verify before installation?
- Confirm the exact axle and differential application, including the listed size or family.
- Check whether the kit is specified for a rear application when that distinction matters.
- Review the included components and shim information against the requirements of the differential setup.
- Follow appropriate service procedures for setting pinion preload; the product descriptions do not provide installation instructions.
