SuperPro Billet Rear Lower Trailing Arm Set for 22-26 Tundra, 24-06 Land Cruiser, Lexus GX/LX

Upgrade the rear suspension of a compatible Toyota or Lexus body-on-frame vehicle with the SuperPro Billet Rear Lower Trailing Arm Set. Manufactured from billet alloy and supplied as a matched pair, these heavy-duty arm assemblies replace both factory rear lower trailing arms.

The rear lower trailing arms control the fore-and-aft movement of the solid rear axle and help maintain its position relative to the chassis. The more positive axle location provided by these complete replacement assemblies can improve rear suspension stability, cornering traction and control during towing, load carrying, off-road driving and normal street use.

Product clarification: Although some distributor catalogs describe ALOY1001K as an “alignment caster/camber control arm,” SuperPro identifies it as a fixed rear lower trailing arm set. These arms are not adjustable and do not provide caster, camber or pinion-angle adjustment.

Recommended Use

Recommended as a heavy-duty replacement or rear suspension upgrade for vehicles used for towing, carrying additional loads, off-road driving or regular street use. These arms replace worn, damaged or flex-prone factory rear lower trailing arm assemblies.

ALOY1001K uses fixed replacement geometry. Vehicles requiring adjustable rear axle or pinion-angle correction should use an application-specific adjustable trailing arm rather than this kit.

What’s Included

• Two SuperPro billet-alloy rear lower trailing arm assemblies
• Preinstalled SuperPro suspension bushings

Installation

Professional installation is recommended. The rear axle must be supported correctly before removing the original trailing arms. Install the replacement arms according to SuperPro and vehicle-manufacturer procedures.

Suspension pivot hardware should receive final tightening at the specified ride position and torque. Inspect the rear upper trailing arms, panhard rod, sway bar links and remaining suspension bushings during installation. A suspension and alignment inspection is recommended after installation.
