Carrier Shims Gm & Ford

Carrier shims for GM and Ford vehicles are essential differential assembly components that control pinion depth and carrier preload in rear axle housings. As a mechanic, you know that proper pinion gear positioning directly affects gear mesh, noise levels, and drivetrain longevity. The RATECH Carrier Shims GM & Ford (part number RAT1105) deliver precision thickness control needed when rebuilding differentials, adjusting gear patterns, or addressing worn carrier bearings. Whether you're performing a complete axle refresh or fine-tuning an existing setup, these shims ensure factory-spec engagement between pinion and ring gear.

RATECH carrier shims are manufactured to tight tolerances that maintain consistent preload without crushing or deformation under load. The compact 3.3 x 0.95 x 4.15 inch form factor fits standard GM and Ford carrier housings, and the lightweight 0.59 lb design integrates seamlessly into differential assemblies. These shims work in tandem with carrier bearings to control axial play—critical for eliminating ring and pinion backlash while preventing excessive bearing preload that causes premature wear. Correct shim stack thickness is determined by your gear pattern analysis and original equipment specifications, making these components non-negotiable for any serious differential work.

These carrier shims are indispensable for restoration shops, fleet maintenance, hot rod builders, and any technician rebuilding open or limited-slip differentials in General Motors or Ford light-duty trucks and performance vehicles. Installation requires proper differential disassembly and the use of a dial indicator or gear pattern kit to verify pinion depth before final shim selection. Always consult your specific axle's service manual for shim thickness ranges and carrier preload torque specifications to achieve optimal gear mesh contact. Stock these RATECH shims for repeat customers and emergency differential repairs where OEM spec compliance is non-negotiable.
