• 2x Tapered Alignment Shims
  
• Installation Instructions

IMPORTANT: Not for 2004 F150 with 2 pin Spring Pack.

Our differential shim kit has been specially engineered to help correct the pinion angle of your vehicle back to factory specifications. An incorrect pinion angle can cause driveline vibrations when driving at speeds, and will severely shorten the lifespan of the differential pinion bearing. CNC machined from billet aircraft aluminum, these are designed to never compress or change angle. They are also manufactured with provisions for center axle alignment pins, and utilize raised grip steps to help keep all components secured in place.
