Alfaholics Race Halfshaft – Rifle Drilled
£495.95 GBP (ex vat)
RCE9025 | RCE9025-1
New design, premium quality and ultra strong. Available in both 25 spline ‘GT Junior’ and 27 spline ‘GTV’ sizes. These halfshafts feature a built in lock ring for the wheel bearing, making wheel bearing changes far simpler than ever possible with standard Alfa shafts. The end flange is scalloped and the shaft is rifle drilled, reducing weight by 0.8KG per shaft – 1.6KG total reducing in unsprung and rotational weight per axle! Available in 25 spline ‘GT Junior’ and 27 spline ‘GTV’ sizes. Priced individually.

Superb new production manufactured exclusively in the UK for Alfaholics by a state of the art limited slip diff manufacturer. These new diffs 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 diff. The new Alfaholics racing diff 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 diff lock-up that not only provides superior traction but also makes the diff 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 new diff 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 diff 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 diff into a road/rally spec diff and vice-versa. We can supply the diff with either setting as standard.The results of the diff 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 new Alfaholics diff is also 7% lighter than the Gripper unit – a useful reduction in unsprung and rotational weight at the rear of the car.This diff 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 LSD 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, diff bearings and seals, wheel bearings, shrink rings (for 2000) and halfshaft oil seals-Full Rebuilt Kit for non-LSD type ‘Small’ AxleFull Rebuild Kit for LSD type ‘Large’ Axle

We have designed and developed this quick shift gear change kit to speed up the actuation ratio of the gear lever and thus improve gearshift times. Rather than manufacture an unsightly remote style gear lever which makes cars look heavily modified, we have CNC machined from billet a new set of gear linkage operating components to fit your gearbox so that the shifter rods themselves are moved at an increased rate for a given movement of the factory style gear lever. This means that your interior keeps its original appearance and the classic renowned Alfa gear lever is retained. We have designed the gear lever stub with a specific 2 degree offset for the gear lever angle to position it slightly towards the driver, the part is reversible so that in 1 orientation it is aligned for LHD and when spun around 180 degrees it aligns for RHD cars. This new system is far superior to the elongated adjustable angle that Alfa used, as that allowed the gear lever to work loose and rotate on its own under heavy use making the car undrivable. We have also uprated the pinch bolt to M8 sizing to ensure a firm and positive tightening.Also included in the kit is a lightweight CNC machined aluminium gear lever with an extended length and modified angle to use in track and competition cars where often the seating position is moved rearward and with an extended steering column for optimised seating position. This gear lever repositions the gear knob near the steering wheel for improved driving ergonomics. The gear lever is also designed to Autodelta GTA specification with a solid un-bushed base to remove lost motion and further improve shift times. Whilst this longer solid gear lever significantly improves the ergonomics and operation for competition cars, it can cause a slight buzzing noise at motorway cruising speeds on the road so for road cars with a more standard seating position, we recommend staying with the standard factory gear lever. This kit needs to be installed by a competent professional who understands the workings of an Alfa gearbox but can be done in situ in the car without removing the gearbox from the car.

CNC machined billet titanium axle tube set for all 105/115 series cars! Massive reduction in unsprung weight to improve traction, ride quality, and handling response. 6.5KG weight saving. Traditionally, the most significant drawback of live axle cars is having a lot of unsprung weight and having the rear tyres stuck at zero camber and toe. With this knowledge in hand, we have designed these tubes not only to save a huge amount of weight, but also to optimise the geometry with built in camber & toe which improves the grip of the rear tyres by optimising the tyre contact patch. Furthermore, we have designed in additional scalloping to the end flanges to further reduce weight, stiffened rear suspension location pickup, adjusted the wall thickness of the tube to increase rigidity for high load/high performance use and built in a motorsport spec breather for improved breathing in continued high speed useage. Available in both large GTV size and smaller GT Junior size.Supplied as a pair of tubes with diff case bearing cup insert. It is also possible to supply a fully built axle as seen in these photos which can include our magnesium centre housing, rifle drilled halfshafts, titanium wheel stud/nut kit, lightweight aluminium rear brake backplates and Superleggera rear brake kit.

As per above kit but put through a final REM Superfinish process. This process polishes the surfaces of the components at a particle level resulting in a super smooth chrome appearance finish. This finish results in the oil getting worked less hard inside the box resulting in reduced frictional losses – the result of this is a nett gain of BHP at the rear wheels.
