This differential represent a huge leap forward in design over our old Gripper units. The old Gripper units used a basic uncoated steel friction plate design and as a result, necessitated a very high preload setting in order to achieve the levels of friction required in a race differential. The Alfaholics racing differential uses the same copper sintered friction plate design as developed by leading World Rally Car teams – M-Sport Ford and Prodrive Subaru. 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/rally 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. The results of the differential development are stunning – both settings offer a dramatic transformation over the old Gripper unit. The race setting provides amazing traction under power (allowing the driver to apply the throttle much harder and earlier) whilst also providing improved adjustability of the car under hard braking and turn in. The road/rally setting provides improved progression under power and further stability under braking than our old road Gripper making the car easier to drive under road & rally conditions. With each setting, the car is more stable during turn in and holds its line much more accurately allowing the driver to place the car with greater precision. When the tail does slide, it is progressive and easy to balance! The Alfaholics differential is also 7% lighter than the Gripper unit – a useful reduction in unsprung and rotational weight at the rear of the car. This differential is available in both small non-LSD and larger 2000 ZF casing sizes, and with 3 different side gear designs to suit small non-LSD halfshafts, bigger 2000 limited slip differential halfshafts and 1300GTA/TZ coarse 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, 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- Full Rebuilt Kit for non-LSD type ‘Small’ Axle Full Rebuild Kit for LSD type ‘Large’ Axle
