Optimized Performance: Smooths torque transfer to lower drivetrain shock and improve mid-corner stability.
Perfect Fit: Made to align with FFEX geartrain geometry for an easy, no-fuss swap.

Will this 40T unit fit every FFEX chassis?

Yes. This replacement is shaped to match standard FFEX diff housings and installs without case modification on factory-layout cars.
