MMX Front Differential Lift Mount / Cradle For F8X / G8x BMW M2/M3/M4

The MMX Front Differential Lift Mount / Cradle (MMR55-1604) is a precision machined replacement for the F8x and G8x M2, M3 and M4 diff mount, designed to reduce movement under load. Fitted on its own in the OEM position, it tightens up the connection between the differential and the chassis, cutting down on drivetrain movement under hard acceleration and load changes, without changing the vehicle's geometry.

The same cradle also solves a problem specific to lowered cars. Lowering an F8x or G8x M2, M3 or M4 changes the geometry of the rear axle, placing the driveshafts under an angle they were never designed to run at. This accelerates wear on CV joints and axle shafts, and increases heat build up at the diff.

G8x Pairing
Paired with the MMX Rear Diff Raised Poly Bush (MMR55-1605), the cradle raises the differential by 10mm, restoring correct driveshaft geometry and taking the strain off the drivetrain. This is the 3-point kit, one cradle (MMR55-1604) and one raised bush (MMR55-1605). For a full 4-point setup, the MMX Dual Differential Mount (MMR55-1606) is added alongside a second raised bush, giving further control over differential movement at the corrected, lifted height.

F8x Pairing
Paired with the MMX Rear Diff Mount Bush (MMR55-1603), the cradle forms the 3-point setup at OEM height. The F8x system works a little differently to G8x here, height adjustment is built into the MMX Dual Differential Mount (MMR55-1001) rather than the bush. Adding the Dual Differential Mount alongside a second bush gives the full 4-point setup, with the OEM or Lifted position set at the mount.

What makes the cradle unique is that one product covers both applications. It isn't a raised version and a stock version sold separately, it's a single cradle where the bush and mount configuration at the point of fitting determines whether it's simply reducing movement, or correcting geometry on a lowered car.

Features:

• Precision machined from 6061-T6 billet aluminium.
• 80A durometer grey polyurethane bushes.
• Reduces drivetrain movement under normal and increased torque loads.
• +10mm raise available, corrects driveshaft geometry on lowered vehicles. On G8x this is set at the bush, on F8x it's set at the Dual Differential Mount.
• Reduces heat build up and premature wear on OEM or aftermarket axle shafts.
• Direct replacement, no modification required, minimal NVH increase.
• Suited to road and track use.
• Fits BMW F8x and G8x M2, M3 and M4.
• Designed to work with the MMX Rear Diff Raised Poly Bush (MMR55-1605) and MMX Dual Differential Mount (MMR55-1606) on G8x, or the MMX Rear Diff Mount Bush (MMR55-1603) and MMX Dual Differential Mount (MMR55-1001) on F8x.

The MMX Front Differential Lift Mount / Cradle is a direct replacement for the OEM diff mount, fitting into the existing mounting points with no modification required. It's designed for minimal NVH increase.
