Superlift Suspension Axle Shims

Superlift Suspension axle shims, also called pinion angle shims or degree shims, correct pinion angle on leaf spring vehicles. Lifting or lowering a vehicle can tilt the axle and cause driveline vibration. Shimming the axle restores proper driveshaft alignment.

Key Features:

• Aluminum construction keeps the shims strong and light.
• Over-axle design for applications where the leaf spring sits under the axle.
• Sold as a pair, so you get both shims needed for one axle.
• Helps reduce driveline vibration by improving pinion and driveshaft alignment after a suspension height change.
• Straightforward installation. Average install time is about 1-3 hours.

Superlift was established in 1975 and builds suspension products for truck and off-road enthusiasts. These shims are a simple, affordable way to fine-tune pinion angle after a lift or lowering install. Choose the variant with the angle that suits your setup.
