Rubicon Express Degree Shim Pair 2.5 inch x 6 Degree

The Rubicon Express Degree shims have been made from steel for maximum durability. They are designed to handle the rigors of trail use. The shims actually become part of the spring pack with included center pins. Many shims in the market float between the spring pack and the spring perch, reducing the engagement of the center pin. This shim design only comes loose or falls out. The steel shims can either be used in the front or rear to set the pinion angles. They are only used for 2.5 inch- wide spring.
