Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

MMX Billet Rear Diff Mount Insert Kit for BMW F2x F3x 1 2 3 4 Series

Sharpen the rear-end response of your BMW F-Series with the MMX billet aluminium rear differential mount insert kit. These precision machined alloy inserts locate within the factory final drive bushes to reduce unwanted movement, helping the car hold its line and feel more predictable on fast road and track use. Available from Nforcd, this proven upgrade delivers a more connected, confidence-inspiring drive without permanent modification.

  • Reduces compliance at the rear final drive mounting points for crisper handling
  • Helps maintain consistent suspension geometry during hard cornering
  • Improves rear axle stability for a more planted, confidence-building feel
  • CNC machined billet aluminium inserts for durability and long service life
  • Quick to install, typically completed in under 60 minutes
  • Fully reversible design that retains the original bushes

Compatibility includes BMW F-Series platforms: F2x and F3x chassis such as F20, F21, F22, F23, F30, F31, F32, F33 and F36 across 1 Series, 2 Series, 3 Series and 4 Series models. Common searches include BMW F30 rear diff mount insert, F20 final drive bush insert, F32 differential bushing kit, F36 rear diff bush upgrade and F2x F3x rear differential mount inserts.

Nforcd knows this MMX kit well and it has been a popular choice with customers seeking a tighter, more precise rear end without adding harshness from a full bush replacement. DIY installation is straightforward and the kit can be removed if you ever wish to return to standard.
