Alfaholics Limited Slip Differential

As used in all our GTA-R builds and our works race cars. The Alfaholics racing differential uses the same copper sintered friction plate design as developed by leading World Rally teams – M-Sport Ford and Pro-drive. This high-friction coating allows the static preload pressure to be set lower, resulting in a more progressive differential lock-up that not only provides superior traction but also makes the differential far easier to drive on the limit; the tail of the car slides more slowly and provides greater driver feedback to control the slide. The copper sintered coating is more durable and eliminates the overheating issues associated with untreated plates under hard competition use. The diameter of the ramp cross pins has been increased in order to reduce internal wear and add significant strength to the diff.

We have carried out extensive testing in order to optimise the differential on both road and track, which has led us to develop two different ramp settings depending on your application. One setting is for race, extreme track day and higher BHP use whereas the other setting is optimised for road application and for less powerful cars. Each differential is manufactured with both sets of ramps on each cup, so you can choose which setting you want, especially useful if your type of use changes! A simple internal swap turns a race differential into a road/rally specification differential and vice-versa.

This differential is available in both small GT Junior (factory non-limited slip differential) and larger 2000 casing sizes, and with 2 different side gear designs to suit small non limited slip differential halfshafts with 25 spline & bigger 2000 27 spline halfshafts. All these parts are interchangeable to allow you a complete choice of fitment options both now and in the future if your application changes.

As fitted to all Alfaholics GTA-R build and race cars.

Also available as a complete bearing and seal set, if you’re fitting a new differential, fit new all bearings and seals too! Includes, differential bearings and seals, wheel bearings, shrink rings (for 2000) and halfshaft oil seals (Listed in the related products below):-
