Rear Shock Options:

  • TT-75110RR – Rear BOSS 2.0 Remote Reservoir Shocks.  For additional performance, the remote reservoir shock will hold more oil to prevent shock fading on rougher applications

Add Upper Control Arms to complete your kit (required for use with extended travel coilovers):

  • Total Chaos Uniball Upper Control arms – 96504 – Maximize your wheel travel and increase your strength while also correcting alignment angles.
  • SPC Adjustable Upper Control Arms – 25480 – The most adjustable UCA on the market.  Correct your alignment angles.  Also great to help with adjusting for tire clearance.

Fitment Notes:
  • If you have rear factory suspension airbags in your Lexus GX460, add the MetalTech Conversion Kit to from the drop down and this kit will work with your vehicle.
  • The factory shock dampening controls (sport/comfort) will be disabled when replacing the shocks on your GX460.
  • On models with the fixed 50Amp Air sus main fuse do not disconnect any sensor or the compressor. Just disconnect the lines to the airbags.
  • On vehicles that have AFS you must leave the height sensor connected. You can either bend the brackets and extend the length of the turn buckle while aligning the lights or you can lock the level into a horizontal position to fix the headlights straight ahead. Do not remove any fuses or relays if these systems are active.
  • We recommend the rear HD coils for GX460’s with 3rd row seating using MetalTech coil conversion kit.
  • Boss front coilovers are only designed to work with stock front lower control arms
