ST Suspensions XA Height & Rebound Adjustable Coilovers for Select BMW 2012-2021 RWD w/o EDC (1822000F)

Fits select 2012-2021 BMW 2-Series, 3-Series, and 4-Series RWD models (including 228i, 230i, 335i, 340i, 435i, 440i, M235i, and M240i) without Electronic Damper Control (EDC).

ST XA Coilovers are engineered for drivers who want to influence more than just ride height. This height and rebound-adjustable system allows you to precisely tune your vehicle's driving behavior, delivering enhanced road control without sacrificing comfort. Hand-built by KW in Germany, every damper is tested on a shock dyno to verify performance before it leaves the factory.

The assembly features galvanized zinc-coated steel struts for maximum corrosion protection. The adjustable spring perches are made from a friction-optimized polyamide composite with a stainless steel insert, preventing the oxidation and seizing common with traditional metal perches. For long-term reliability, a multi-layered pressure-resistant sealing package and a low-friction piston band operate within the hardened chrome piston rod assembly.
