Product Details

This Whiteline Rear Upper Trailing Arm Set fits the 2025-2027 Toyota 4Runner. Placement: rear. Part number KTA334A. Chassis code: N400. The kit contains 2 arms.

Control arms decide how the wheel leans and points as the suspension moves. Adjustable ones allow those angles to be changed instead of left to chance, which supports even tire wear and consistent grip. The polyurethane used here deflects much less than the original rubber under the same load.

Expect an easy job of about 2 hours. Plan on a wheel alignment afterward. To go with it on the 4Runner, see 21mm Rear Sway Bar Mount Bushing Kit and 35mm Adjustable Front Sway Bar.

Features

  • Bushing material: The bushing material is polyurethane, a firmer choice than rubber.
  • Install guide: Instructions for fitting are packed in the box.
  • Easy to fit: Installation does not call for special skills or tools.
