Description
Correct drive shaft angles and improve vehicle handling across multiple truck chassis with the Specialty Products Company (SPC) 89399 Heavy Duty Zinc Axle Alignment Shim. Featuring a 1.5-degree (1-1/2°) wedge angle, this universal shim is designed for 2WD and 4WD solid axle trucks, SUVs, and trailers.
The SPC 89399 features an innovative pre-scored "break-away" design, allowing technicians to easily snap the shim to fit 3-inch, 3.5-inch, or 4-inch wide leaf spring pads. Cast from high-compression zinc alloy, these shims resist crushing, distortion, and corrosion far better than standard aluminum shims, making them essential for eliminating driveline vibrations and tire scrubbing after lift kit installations.
