Rear height adjuster for suspension setups where the spring lives in a control-arm bucket rather than on the damper body — a separate-spring-and-shock configuration common on many sedans and crossovers. Unlike a true coilover where ride height moves with the damper, in this design the spring sits in the OEM bucket and the height adjuster threads into the spring perch to raise or lower the rear of the vehicle. This adjuster lets rear ride height be set independently of the damper. The unit is sized to vehicle-specific dimensions; verify the part number on the listing against the application list before ordering.
BC Racing was founded in Taiwan in 1999 by Bor-Chuann Enterprise Co., Ltd., originally as an OEM and ODM manufacturer of shock absorbers for many of the world's best-known coilover brands. In 2004 the company launched its own consumer brand and rapidly grew into one of the largest aftermarket suspension manufacturers in the world, with more than 1,100 vehicle-specific coilover kits in production. Every BC Racing damper is built in-house — design, machining, valving, and assembly all happen under one roof — and each unit is dyno-matched before it leaves the factory. North American distribution is handled by BC Racing North America, who back every kit with a one-year manufacturer's warranty against defects. You can read more about the brand and the full series lineup (BR, DS, RM, ER, HM, ZR, and ZX) at bcracing-na.com.
