Strengthen and refresh the rear suspension of a compatible Toyota or Lexus body-on-frame vehicle with the SuperPro Billet Rear Upper Trailing Arm Set. Manufactured from billet alloy, these heavy-duty arm assemblies replace the factory rear upper trailing arms as a matched pair.
The rear upper trailing arms help control the fore-and-aft movement of the solid rear axle and maintain its position relative to the chassis. More positive axle location can improve rear suspension stability, cornering traction and control during towing, load carrying and off-road driving.
Product clarification: Despite some distributor catalogs describing ALOY1002K as an “alignment caster/camber control arm,” SuperPro identifies these as fixed, non-adjustable rear upper trailing arm assemblies. They do not provide an on-vehicle caster, camber or pinion-angle adjustment.

Recommended Use
Recommended as a heavy-duty replacement or suspension upgrade for vehicles used for towing, load carrying, off-road driving or general street use. These fixed arms replace worn or flex-prone factory rear upper trailing arm assemblies but do not provide adjustable pinion-angle correction.
Vehicles requiring adjustable rear axle or pinion-angle correction should use an application-specific adjustable trailing arm rather than ALOY1002K.
What’s Included
- Two SuperPro billet-alloy rear upper trailing arm assemblies
Installation
Professional installation is recommended. Support the rear axle correctly before removing the factory trailing arms and install the replacement arms according to SuperPro and vehicle-manufacturer procedures.
Final tightening of suspension pivot hardware should be completed at the specified ride position and torque. Inspect the remaining rear suspension bushings and arms during installation, and check the vehicle’s rear suspension geometry after the work is completed.
