Leaf Spring Shim Kit, 6 Degree, 1966-77 Ford Bronco

6 Degree Shim Kit for Lifted 66-77 Classic Ford Broncos. Mounts between the Rear Leaf Springs and the Rear Differential Housing Perches on your Early Bronco to correct the pinion angle. When you install a suspension lift in an Early Bronco, it changes the rear pinion angle causing the driveline to bind. These shims angle your leaf springs by 6 degrees to help bring your driveshaft back into alignment. Kit includes two 3/8 inch leaf spring center pins.

NOTE: Factory pins are 5/16 inch. The included pins are for TBP lifted leaf springs. If you need 5/16 inch center pins, please notate that when you order.
