Product Details

The Ground Control Weight Jack Rear Height Adjuster for the 2019-2026 BMW 3 Series AWD/RWD (G20) is a precision Ground Control articulating weight jack height adjuster kit engineered to upgrade your 3 Series. All components are plated or anodized to resist corrosion and maximize longevity, and like everything Ground Control builds it is made in the USA to exacting tolerances.

Ground Control's articulating weight jack height adjusters mount the rear springs of your BMW. They allow the spring to articulate throughout its compression and extension, so it keeps a linear shape and therefore a linear rate throughout its travel, just how your springs are tested, for more consistent bump travel. The control arm on these cars has a tendency to bow or bend the spring when compressed; these articulating weight jack height adjusters eliminate that problem.
