Part number 41-284544 combines Bilstein’s advanced damping technology with a smooth-body coilover design, providing improved ride comfort during everyday driving and confident control over large suspension inputs. This module includes a remote reservoir to help increase cooling capacity and an anodized, bolt-on chassis mount for secure installation.\u003cbr\u003eBilstein ZoneControl CR technology uses three independent pistons to deliver three stages of compression damping and two stages of rebound damping. This position-sensitive design automatically adapts damping performance based on suspension travel, helping the vehicle remain composed across changing road conditions without relying on externally adjustable damping. The monotube construction and 60-millimeter piston provide consistent performance, while the zinc-plated damper body and black spring offer durable service in demanding environments.\u003cbr\u003eThe threaded spring seat allows ride-height adjustment from 0 to 3.8 inches, depending on vehicle application, making it easier to tailor suspension setup and clearance requirements. The coilover is supplied with a 650-pound-per-inch front spring, special upper mount, eye-style lower mount, and integrated spring seat. Aftermarket upper control arms are required for installation. Verify vehicle compatibility, corner position, suspension configuration, and application-specific adjustment range before ordering.
