Pinion shims are thin pieces of metal that may look unimportant, especially when dealing with suspension sets. But these metal plates are sneaky important and play a vital role in fixing driveline geometry that can lead to an unbalanced pinion angles, driveline vibrations, and damage to the differential system.

Belltech Pinion Shims are designed to fit most trucks and SUV leaf springs. These shims are installed by loosening the bolts fastening the leaf springs and spring perch, then inserting the plate in between just below the leaf pack.

Belltech has engineered many lowering innovations in suspensions that lower the ride height of sport trucks, muscle cars, large pickups, and SUVs. Since developing the drop spindle back in the 80s, Belltech has been cranking out innovative products that kept blowing the minds of low riders. Belltech became known for state of the art stock suspension replacements that not only perform better but drops a vehicle ride height.

The American vehicle customization market was never the same again.

Through the years, Belltech has consistently produced high-quality products that serve a demanding niche of racers and custom builders. The company grew from its simple roots to a large 75,000 SQM facility where Belltech assembled the finest research and development team focused on developing new products and refining existing ones.

Belltech's merger with the German company KW Suspensions - one of the top manufacturers of racing suspensions - infused more engineering innovations because of the latter's considerable experience in tuning and refinement of premium vehicles and racing cars.

Belltech now offers a complete suite of lowering, leveling, lifting, and alignment kits for almost any 4 wheeled vehicle. From classics like the Chevrolet C10 pickups and the Ford F-100 to newer models like GM Silverado and Ford F-150, Belltech has all the components you need for a successful and safe custom suspension build.
