BMW E36/E46 Rear Upper Control Arms

Just Engineering BMW E36/E46 Rear Upper Control Arms

Just Engineering has revolutionized the design of the BMW E36 and E46 rear upper control arm with competition use at the forefront. Traditionally, replacing these arms requires removing the differential to access the subframe bolt—a task that is impossible during a quick trackside repair or between drift heats. These arms solve that problem with a unique two-piece design that allows for rapid replacement in under five minutes.

Engineered for maximum durability and ease of maintenance, these arms move the adjuster to the knuckle side for effortless alignment changes while on the car. Built from high-strength structural steel and chromoly tubing, they are designed to withstand the rigors of professional motorsport while maintaining precise suspension geometry.

Key Features

• Two-Piece Quick-Change Design: Allows the outer arm to be replaced in minutes without removing the differential or the inner subframe bearing.
• Knuckle-Side Adjustment: The adjuster is positioned at the knuckle for significantly easier alignment tweaks while the vehicle is on the ground.
• High-Strength Construction: Fabricated from structural steel and chromoly tubing for superior rigidity and impact resistance.
• Precision Welding: Every arm is TIG welded to ensure maximum joint integrity and a professional finish.
• Premium Hardware: Features forged chromoly hardware and high-quality bearings for long-lasting performance.
• OEM Integration: Includes an OEM-style sway bar mount to maintain full compatibility with your existing suspension setup.

Fitment / Applications

• BMW 3 Series E36 (All Models)
• BMW 3 Series E46 (All Models)

Notes

• The inner bearing section is designed to be overbuilt, ensuring it remains intact during a crash so only the outer arm section needs replacement.
