The TeraFlex JT: 0.5” Rear Lower Bump Stop Strike Pad Shim Kit extends the reach of the factory bump stops on lifted JT Gladiator models to soak up energy during hard compression and suspension movement. Combine with our JT: 1.5” Rear Upper Bump Stop Strike Pad Extension Kit(s) (# 1969300) and 0.5” Rear Upper Shim Kit(s) (# 1969400) to fine tune your strike pad height.
