What This Product Does:

  • Support & alignment: The trailing arms maintain alignment and control of the rear wheels under acceleration, braking, and load changes.
  • Reduction of play: Worn bushings allow movement or “slop” in the arm, degrading handling precision and causing clunks or instability.
  • Transmission of force: The trailing arm bushing sees load from acceleration, deceleration, and road irregularities, so a firmer bushing transfers forces more consistently.
  • Improved component longevity: Correctly supported trailing arms reduce stress on adjacent components (arms, mounts, subframe).

Symptoms Of Worn Trailing Arm Bushings:
  • Clunks / knocking noises at the rear, especially over bumps
  • Rear-end instability or “wandering” under dynamic loads
  • Uneven or accelerated rear tire wear, from alignment wandering
  • Vibration or harshness when the rear suspension flexes
  • Reduced grip or confidence in corners, due to less precise rear control

Why This Kit / Upgrade Matters:
  • Restores precision and geometry — tighter bushings help maintain alignment under load (cornering, braking)
  • Improves rear-end stability — reduces unwanted deflection improves overall handling confidence
  • Swaps wear for performance — old rubber often softens with time; upgraded HD compound resists fatigue
  • Saves cost vs full arms — this kit allows reuse of original arms rather than having to replace with new arms
  • Tools included — the kit comes with the necessary press tools and lubricant, making the job easier and more accurate
  • Balanced stiffness — with ~25% stiffer than OEM, it offers performance improvement without excessive harshness
