    • Toytec Rear Bump Stop Drop kit - Designed to work with our Superflex rear coils allowing your rear bump stops to function properly protecting your rear shocks from damage and keeping the rear tires from hitting the fenderwell.

Its heavy-duty Dual Durometer Rubber provides smooth progressive dampening and greatly reduces hard bottom outs. With DuroBumps, gain better off road control and comfort vs the harsh-on-contact OEM bump stops and eliminate the shell-shock effect experienced on hitting those larger bumps.
