Bushing Inserts for 5, 6 and 7 Series F Chassis

Your F chassis differential mount is flexing under power, creating that annoying shift "dip" and killing your connection to the drivetrain. These precision-machined inserts eliminate the slop without the $1,000+ subframe drop BMW charges for mount replacement.

Performance Gains

Immediate transformation in shift quality and drivetrain response. The OEM rubber mount flexes under load, especially during aggressive shifts or hard acceleration. These CNC-machined aluminum inserts lock the differential solid, delivering crisp gear changes with zero delay between throttle input and power delivery. You'll feel every bit of torque transfer directly to the wheels instead of getting absorbed by sloppy rubber mounts. Particularly noticeable during spirited driving when the drivetrain is working hardest.

Installation & Supporting Mods

Straightforward install that doesn't require dropping the subframe like OEM mount replacement. The inserts press into the existing mount housing, reinforcing the weak points without full removal. Basic hand tools and a jack get the job done in your garage. Install video available on our site, plus text support at 813.252.1025 for any questions during the process. Perfect complement to upgraded motor mounts and transmission mounts for a completely solid drivetrain package. Need help planning your build or stuck mid-install?
