Having issues shifting smoothly through the gears? Our Ford MMT6 Gearbox service and upgrade replaces all the fragile standard synchros with our carbon lined heavy duty components along with all new upgraded bearings. This ensures accurate selection when going through the gears, even under hard acceleration. A full teardown, motorsport grade cleaning and inspection are performed before re-assembly making sure your gearbox is more reliable and performs better than new.

Shipping your gearbox to us is easy. We send you a heavy duty shipping container with return label. Simply place your gearbox in the container and send it back to us for upgrading. Select this $125.00 option when checking out. This option applies to the lower 48 United States only.

Add an optional Quaife ATB Differential or WPC Gear treatment for maximum performance.

  • Faster, more accurate shifting
  • Upgraded components
  • Optional Quaife ATB
  • Optional WPC Gear Treatment

About WPC
he WPC process is unrivaled in treating engine parts and other surfaces that have contact points of friction. WPC is superior because it is not a coating; it is a permanent surface treatment that reduces friction while strengthening the part. It's unique micro-dimple formation pattern greatly reduces friction and is unmatched by conventional methods of surface treatment.
