The MMX Performance F8X Dual Differential Mount (MMR55-1001) is engineered for the BMW F87 M2, F80 M3, and F82 / F83 M4 platform to add a second rear differential mounting point. Precision-machined from 6061-T6 billet aluminum, the mount increases support at the rear differential and helps reduce unwanted drivetrain movement under load.

The Dual Differential Mount can be installed in the OEM differential position with the factory bushings or paired with two MMX Rear Differential Polyurethane Bushings (MMR55-1603) for a firmer mounting configuration. When combined with the MMX Front Differential Lift Mount / Cradle (MMR55-1604), the differential can also be positioned 10mm higher to improve drivetrain geometry on lowered F8X applications.

Product Details:

• Precision-machined 6061-T6 billet aluminum construction
• Adds a second rear differential mounting point
• Designed to increase differential support and reduce drivetrain movement under load
• Can be used with factory bushings or two MMX Rear Differential Polyurethane Bushings (MMR55-1603)
• Supports OEM differential position or +10mm raised configuration when paired with the MMX Front Differential Lift Mount / Cradle (MMR55-1604)
• Raised configuration is designed to improve driveshaft and axle geometry on lowered vehicles
• Helps reduce heat buildup and premature wear at the axle shafts when used in the raised configuration
• Direct-fit installation with no permanent modification required
• Designed for minimal increase in NVH
• MMX SKU: MMR55-1001

4-Point Differential Kit Configuration:

• 1 x Front Differential Lift Mount / Cradle (MMR55-1604)
• 2 x Rear Differential Polyurethane Bushings (MMR55-1603)
• 1 x F8X Dual Differential Mount (MMR55-1001)

Ultimate Differential Kit Configuration:

• 1 x Front Differential Lift Mount / Cradle (MMR55-1604)
• 2 x Rear Differential Polyurethane Bushings (MMR55-1603)
• 1 x F8X Dual Differential Mount (MMR55-1001)
• 1 x F8X High Capacity Differential Sump (MMR55-1000)

Notes:

• The Dual Differential Mount can be installed in the OEM differential position or used as part of a +10mm raised differential configuration.
• The +10mm raised position requires the MMX Front Differential Lift Mount / Cradle (MMR55-1604).
• Professional installation is recommended.
• Includes a 1-year manufacturer warranty against defects in materials and workmanship.
• Designed and tested in the United Kingdom.
