Peloquin 020 diffs are supplied with bolt kits, bearings, and a transferable limited lifetime warranty. These units bias torque more aggressively than the Quaife 020.
Special note from Scott F. Williams (USRT, rally driver: retired.): "The first time I experienced a Peloquin 020 diff was years ago at the Ski Sawmill Pro Rally. Up ahead a line of big horsepower cars launched each minute. The road surface was a fine silt by the time westarted in our tank of a Rabbit GTI -the mighty "Warpig", . The first thing I perceived was 25% improved acceleration -especially while exiting tight turns. The next thing was increased communication from the steering wheel during throttle changes. Power on/off under and oversteer at the traction limit were now very easily distinguished. Before that it was just "mush".
