The Belltech 4975 is a 2-degree pinion shim set engineered to resolve driveline vibrations by correcting the pinion angle of your rear axle. Made from durable extruded aluminum, these shims are designed for universal fitment on leaf spring packs measuring either 2.5 or 3 inches in width. They accommodate both single and double center pin configurations, making them a versatile solution for various applications. This shim set is particularly useful after suspension modifications that alter the vehicle's ride height, as it helps to restore proper driveshaft alignment. The kit provides the necessary components to address common driveline angle issues, thereby reducing unwanted vibrations and promoting a smoother ride. Each package includes two 2-degree shims, two new spring center bolts, and two nuts, ensuring you have the essential hardware for installation. Belltech emphasizes that they are not liable for incorrect product purchases and advises verifying fitment manually. This product is intended for use with leaf spring equipped vehicles where pinion angle adjustment is needed.
