The weakest link in the classic Mini's drivetrain is the differential pin and cast cage. This super strong, tried and true, heavy-duty diff is a must-have upgrade for any hot road car or competition Mini. It features crossed strengethend pins, moly coated spider gears, new thrust washers, and a hardened steel cage. Not only does it handle more power, but the extra gears mean a much smoother performance and much less tendency for torque steer. It can be used in any manual gearbox configuration.
