More info

Traxxas TRX-4 Lift Kit lifts your TRX-4 so you can run larger 2.2" wheels and tires and gain extra ground clearance for rough terrain. The Long Arm Lift Kit swaps in longer components and a revised servo mount so suspension and steering geometry stay correct even with the taller setup.

Key Features

  • Lifts the TRX-4 to accommodate 2.2" wheels and tires, increasing obstacle clearance.
  • Longer GTS aluminum shocks for improved suspension travel and more consistent damping.
  • Matched springs installed with the shocks to help retain proper ride height and balance.
  • Longer driveshafts to span the raised suspension without binding.
  • Extended suspension links to maintain axle alignment and handling characteristics.
  • T-Lock cables included so locking-differential function works with the new geometry.
  • Revised servo mount that lowers the servo position to preserve suspension and steering geometry after the lift.

Install is a Challenge

Installing this was way more work than I expected, mostly bc of the long lines for the lockers. It's meant for bashing/monster truck stuff but you can tweak it for crawling. I added some pics showing how I changed the servo drop so I could get full articulation. I swapped out the springs for .30 rate ones, put in 10wt oil, and took out the spacer from the shock shaft. It's a bit more tippy now but adding 500g of brass to the axles helped, except for side hilling. Gonna add the treal +15mm wheel spacers next, hope that'll fix it.
