Product Description

The Bilstein 41-326343 B8 8112 ZoneControl CR DSA+ coilover is a premium front left suspension module designed for the 2003-2009 Toyota 4Runner, Lexus GX470, and Toyota FJ Cruiser platforms. Engineered for serious off-road capability and daily driving comfort, this system features Bilstein's advanced triple piston ZoneControl technology, delivering position-sensitive damping that adapts to both small road imperfections and large suspension impacts.

Equipped with Dual Speed Adjustability, this coilover allows independent tuning of high- and low-speed compression, giving drivers precise control over ride characteristics. The remote reservoir increases oil capacity for improved thermal performance, while the integrated hydraulic bump stop helps manage extreme compression events. With adjustable ride height ranging up to approximately 4 inches of lift, this system is ideal for lifted builds seeking enhanced stability, durability, and all-terrain performance. :contentReference[oaicite:0]{index=0}
