Finally, a spring cup designed specifically for 5.5" front springs! This spring cup is designed to allow for max clearance of stock mount shocks as well as much tighter fitment into the I.D. of a 5.5" diameter spring.  Installed height from the spring pad to the top of the cup is 2.25", Can trim to fit as needed. Comes with gloss black powdercoat finish.
 
*Please note that on heavier rate springs (over 1000lbs) or on springs made with thicker wire, you may need to use a shim to lift the locator tabs up out of the coil for proper fitment. Factory 43 spring shims are designed to fit this cup.
