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.

Ubolts:  Choose from standard 7.5″ ubolts or our ubolt flip kit.  The ubolt flip kit will allow you to turn your ubolts facing upward, providing additional ground clearance.

Rear Bump Stops:

  • Rear Bump Stop Extension kit- 43007 – Recommended for use with add-a-leafs or complete leaf spring packs, these will allow your factory rear bump stops to function with the lift.  (*Requires drilling 2 holes per side).
  • Durobumps – Tacoma rear bump stops eliminate the shell shock effect we’re all familiar with when hitting OEM bump stops. Our dual durometer bump stops easily absorb hard impacts and help keep the vehicle stable at higher speeds in rough conditions. The 4.25″ rear bump stop is intended for trucks with a rear lift of 2″ and extended shocks of up to 1″. These bump stops have been designed to stop wheel up travel under articulation prior to extended shocks bottoming out.  Can be used with or without the Ubolt flip kit.

  • Total Chaos Uniball Upper Control arms – 96504 – Maximize your wheel travel and increase your strength while also correcting alignment angles.
