Rear Axle Set Up Spacer Kit

The Rear Axle Set Up Spacer Kit by King Racing Products is purpose-built for mechanics and suspension tuners who demand precision in rear axle alignment and geometry correction. This steel spacer kit addresses a critical challenge in performance builds and restoration work: achieving proper pinion angle, axle centering, and load distribution across the rear housing. Whether you're upgrading a lift kit, correcting manufacturing tolerance stack-up, or fine-tuning suspension geometry on a modified truck or SUV, this spacer kit delivers the straightforward solution that separates amateur setups from professional installations.

Manufactured from high-strength steel in a natural finish, the Rear Axle Set Up Spacer Kit provides repeatable, durable shimming to dial in rear axle position relative to the frame. The kit's compact footprint (7 x 3.75 x 9.25 inches) and lightweight design (1.35 lbs) make it easy to install, adjust, and remove without requiring frame modifications or welding. The natural steel construction resists corrosion under typical operating conditions while maintaining dimensional stability—critical when even 1/16 inch of error can introduce drive-line vibration, tire wear patterns, or binding in the differential. These spacers work in concert with factory or aftermarket leaf spring isolators and are engineered to handle the lateral and vertical loads inherent in truck and SUV rear suspensions.

This kit benefits anyone performing suspension work on light-duty trucks, work vehicles, or performance builds where axle alignment cannot be left to chance. Installation is straightforward: position the spacer shims between the axle housing and frame mount points, torque fasteners to factory specifications, and verify pinion angle and centering with a level or dial indicator. The Rear Axle Set Up Spacer Kit is compatible with most rear-axle designs that use bolt-on or welded frame brackets, making it a versatile choice for Ford, Chevrolet, Dodge, and similar platforms undergoing lift installation or geometry correction.
