The KEIN Adjustable Rear Arms Kit is designed to restore and fine-tune suspension geometry on lowered, lifted, or performance-oriented vehicles. As a critical link between the wheels and the chassis, rear suspension arms control wheel trajectory and transfer longitudinal and lateral forces to the vehicle body—making precision and strength essential.

KEIN rear arms feature a rotating threaded adjustment section, allowing accurate correction of suspension geometry without removing the arms from the vehicle. This design enables precise control over wheel alignment angles, making them ideal for street driving, aggressive performance setups, drifting, and track use.

Factory suspension arms are engineered for OEM ride height and alignment specifications. Once ride height or suspension characteristics are altered, geometry can fall outside optimal ranges. KEIN adjustable arms provide the correction needed to maintain stability, traction, and tire wear.
