RS*R XLIN144MA Best-i Active Coilover Kit

The RS*R Best-i Active Series coilovers are designed to work seamlessly with factory AVS (Adaptive Variable Suspension) and DDS (Dynamic Damper System) equipped on select Lexus, Toyota, and Infiniti models. Unlike conventional aftermarket coilovers that disable these systems, the i☆SHOCK Active series retains factory controls, allowing the factory actuator to function with the aftermarket coilover so dampening and control systems remain operational.

Key Features:

• Hand-assembled monotube damper system with laser-cut upper mounts, hand-welded lower brackets, and vehicle-specific valving
• Main damper adjustments done through factory AVS controller, with secondary 24-way adjustment dial located at the base of the dampers
• Steel damper body with 40φ internal diameter for increased oil capacity and improved heat dissipation (46φ for strut-type vehicles)
• Aluminum upper plate with rubber bush upper mount for comfortable, quiet ride quality while maintaining responsive handling
• Optimized piston stroke design maintains maximum ride comfort while allowing significant ride height adjustment

Preset approximate height drop of -30mm (-1.2 inches) front and rear, with maximum adjustment range of +10mm to -85mm (+0.4in to -3.4in) front and -5mm to -90mm rear. RS*R coilovers are covered by a limited 1-year or 12,000-mile warranty from date of purchase, covering manufacturing defects.
