Product Description

A new Coilover series that can be used with the AVS system used on various Lexus and Toyota models have been released. The AVS system does not work with aftermarket shocks and coilovers. The I SHOCK Active series, on the other hand, preserves factory controls. The factory actuator can now be utilized on an aftermarket Coilover to keep the dampening and control systems operational. The non-adjustable damper force model "RS-R Basic I Active," the adjustable damper force model "RS-R Best I Active," and the extremely low-down look with AVS system "RS-R Black I Active" are now available. The RS-R Coilovers are all hand-assembled Monotube systems that are specifically engineered to increase ride quality, performance, and comfort. To assure quality and detail, components such as laser-cut top mounts, hand-welded lower brackets, and vehicle specific valving are all constructed by hand.

NOTE: Compatible with factory AVS; fitment is unconfirmed on convertible models
