Bilstein B8 8112 ZoneControl CR Front Right Coilover Module 41-324165

The Bilstein B8 8112 ZoneControl CR front right corner module, part number 41-324165, is a direct-fit position-sensitive coilover designed for select light trucks and SUVs, including the 2012–2016 Lexus GX460 and 2012–2016 Toyota 4Runner. This complete module combines a monotube steel damper, coil spring, threaded spring seat, and remote reservoir to deliver controlled handling and improved ride comfort across changing terrain and suspension loads. Its smooth-body coilover construction and special upper mount are engineered for dependable installation and performance.
ZoneControl CR technology uses a triple-piston design with three independent compression zones and two rebound zones. This position-sensitive damping system automatically adjusts control according to suspension position, helping provide comfortable everyday driving characteristics while maintaining control during larger suspension inputs. The remote reservoir increases fluid capacity and cooling performance, while the included bolt-on anodized reservoir mount supports secure chassis installation. Damping is non-adjustable, and the system does not include a protective boot.
The threaded spring seat allows ride-height adjustment from 0 to 3.8 inches, depending on the vehicle application. The module includes a 600-pound-per-inch front main spring, with optional heavy-load springs available under Bilstein part numbers 53-291387 and 53-332837. The damper features a 60 mm piston, 22 mm shaft, 14.1 mm eye-style lower mount, and EVO Grey damper finish with a black spring. Its extended length is 22.80 inches and its collapsed length is 17.99 inches. Professional installation and application verification are recommended before purchase.
