Product Description
The Whiteline KTA334 rear upper trailing arms give 2022-2026 Toyota Tundra and 2024-2026 Tacoma owners a way to adjust rear differential pinion angle after changing ride height. The heavy-duty turnbuckle design adjusts on the truck, so the rear suspension can be dialed in without removing the arms every time an adjustment is needed.
This is a useful upgrade for lifted trucks where rear driveline geometry needs more attention than the factory arms allow. The kit includes a pair of rear upper trailing arms and is designed to work with the factory rear suspension mounting points.
When Adjustable Rear Trailing Arms Make Sense
Not every lifted Tundra or Tacoma needs adjustable rear trailing arms. They make the most sense when the rear suspension height has changed enough that you need to correct pinion angle or fine-tune how the truck behaves under acceleration.
It is a good idea to have the suspension checked after installing the arms. Set the truck at its final ride height first, then make any adjustments needed for your specific lift and driveline setup.
