Product Details

If you're looking to dial in the stance and handling of your 2021-2023 BMW M440i xDrive, this ST XA Coilover Kit is a solid option. It lets you precisely adjust both the ride height and the damping characteristics, giving you control over how your car looks and feels on the road. This kit is designed to work with M440i xDrive models that do not have electronic dampers from the factory.

The spring perches are made from a durable, friction-optimized polyamide composite with a stainless steel insert. This combination prevents corrosion between the strut and perch, ensuring that you can adjust your ride height smoothly for years to come. The stainless steel insert adds strength where it's needed most. ST Suspensions tests each damper on a shock dyno before it ships, and this XA kit offers 16 distinct clicks of rebound damping adjustment. You can easily tune the driving dynamics from a more comfortable ride to a sportier feel using the adjustment knob and the included manual.

The galvanized zinc-coated steel struts offer good corrosion protection, and a built-in dust protection system keeps dirt and debris away from the hardened chrome piston rod and valve packs. These coilovers are built by hand by the experts at KW in Germany, so you can expect a well-made product. You'll get seamless ride height adjustment thanks to the composite spring perch and the thread pitch. This kit is designed to fit right on your M440i xDrive without needing additional modifications for height and damping adjustment.
