Quaife Based SFRE Differentials

Since 1996 we have built the strongest, most reliable Quaife type differential for chain and belt drive cars. Our units have won at the track, in hillclimbs and 7 Natioal Solo championships. Available configured for either cv joints or tripode joints, these units are oil lubed for easy service. Our package comes ready to install with mount plates, bearings and easy to use chain adjusters.

A word on reliability:…in 1998 we installed a differential in Bill Goodale’s new Dragon F1 behind a full house Hooper Artic Cat 2 stroke. These motors put out up to 230 HP. In 2006 the car was reconfigured to use a Kawasaki ZX12r motor. During all of this time, after 100’s of standing starts at full power, there has never been a single differential failure.
