4 degree shim
Fits 2.5in wide springs
Center pins are not included
Sold in pairs
We make these shims from solid steel for maximum durability. Designed to handle the rigors of trail use, these shims actually become part of the spring pack with included center pins. Many other shims on the market float between the spring pack and the spring perch reducing the engagement of the center pin. Our design will not come loose or fall out. Can be used front or rear to set pinion angles. 2.5in wide springs only. Center pins not included.
