Steel shims to go between your leaf springs and your spring perch. These are used on leaf spring vehicles in order to adjust pinion angles and achieve proper drive line geometry. Our shims are 2.5" wide, machined from steel, and include a new set of center bolts. Select size (in degrees).
Use the calculator below to determine the right size shims. The shim calculator figures out the current joint angle, takes into account how much the drive shaft slope changes as a result of the shim, and aims to achieve a 2-3 degree net joint angle. The calculator is only for double cardan rear drive shafts. If you have something else or if you have questions, give us a call. 801-737-0757
Was nervous that the math wasn’t working out and I’d need a much larger shim. Gave them a call and they verified my measurements with me and the 2 degree shims provided much more angulation than expected and worked perfectly!
Worked awesome . Looked great
