Maximize rear suspension performance with the Xcessive Manufacturing Pro Comp Rear Suspension Arms for the 2001–2005 Lexus IS300. Designed for competitive drifting, road racing, and track use, this complete rear arm package replaces the factory suspension arms with fully adjustable, high-strength components engineered for precise alignment, increased articulation, and zero deflection.

Unlike factory rubber bushings, the Pro Comp series utilizes motorsport-grade heim joints to deliver maximum suspension control and responsiveness. Every arm is designed around factory mounting locations while providing a broad range of adjustment for aggressive alignment settings on lowered vehicles.

Finished in durable chrome, these arms combine race-proven performance with a clean, show-quality appearance.

Complete Rear Suspension Solution: Upgrade the rear suspension with fully adjustable rear upper control arms, traction rods, and toe rods.

Motorsport-Grade Heim Joints: Solid spherical bearings eliminate suspension deflection for maximum precision and feedback.

Optimized for Lowered Vehicles: Corrects suspension geometry while allowing aggressive alignment settings.

Heavy-Duty Construction: Engineered for exceptional strength, durability, and long service life.

Chrome Finish: Durable chrome plating provides corrosion resistance and a premium appearance.

Rear Upper Control Arms (RUCA)

The Rear Upper Control Arms feature a simplified high-strength design that minimizes unnecessary welds while maximizing structural integrity. Adjustable from just under factory length to approximately +6 degrees of camber correction, these arms help restore proper tire contact on lowered vehicles.

The outer ball joint angle has been redesigned to improve articulation at lowered ride heights, while Xcessive's sealed, greaseable outer ball joint provides greater articulation than traditional heim-style outer joints. Combined with a 4130 chromoly double adjuster, these arms allow precise alignment adjustments without removing the arms from the vehicle.

Traction Rods

The Pro Comp Traction Rods utilize solid heim joints at both ends to eliminate suspension deflection under acceleration and braking. Designed specifically for motorsports, they provide maximum chassis control and precise suspension movement during aggressive driving.

Toe Rods

The Pro Comp Toe Rods feature solid heim joints for accurate toe adjustment and improved rear suspension stability. Their rigid design provides consistent alignment under heavy cornering loads, making them ideal for drift and road racing applications.
