Front Bump Stops:

  • DuroBumps are proudly made in the USA with dual durometer (hardness) rubber that provides smooth progressive dampening and greatly reduces hard bottom outs. This allows for more control and comfort compared to OEM bump stops that are harsh on contact. With DuroBumps installed, the shell-shock effect experienced when hitting the OEM bump stops is completely eliminated.

Rear Bump Stop Options:

  • 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.
  • DuroBumps - DuroBumps 4.25″ rear bump stops are intended for vehicles that have rear lifts of 2″. 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.
Rear Lift Options:
  • Toytec Rear Superflex Coils: - Our BOSS suspension kits come standard with Toytec RCC2.0 rear springs- These springs offer 2" of lift with stock rear weight with the best overall ride quality and rear articulation.
  • Optional HD Rear Superflex coils offer additional weight capacity. Recommended 150-200 lbs of constant load for 2-2.5" of lift.

Rear Shock Options:

  • Toytec 2.0 Aluma Series Rear shocks designed for 1-3" lift. Shock bodies are hard-anodized aluminum for cooler operation and longer lasting in the elements. Fully rebuildable. Perfect match to our Aluma coilovers.
