Lock In Precise Rear Axle Location Under Load
The factory upper trailing arm on the Ram 2500 relies on soft rubber bushings that break down over time, allowing the rear axle to wander under load and reducing overall stability. This Whiteline KTA480 upper trailing arm assembly replaces the worn factory component with a stronger design that keeps the axle located precisely during towing and hauling.

Alignment Components
Shop alignment components, camber kits, caster kits, and adjustable control arms at Black Ops Auto Works.

This collection includes options from Black Ops Auto Works, AAD Performance, SPC Performance, Eibach, SuperPro, Whiteline, and other suspension brands. Adjustment capability varies by product. A camber kit does not automatically provide caster...
