Alfaholics Semi-Automatic Gearchange Kit

Designed for use with the Alfaholics 6-speed sequential gearbox. This kit allows full throttle clutchless upshifts and clutchless downshifts with throttle blipping to match engine revs to gear speed. The system incorporates the very latest ‘closed-loop’ software using an ECU in conjunction with feedback sensors to modify its own operation in response to the sensor inputs, all in real-time. It uses these sensors to monitor the gear position sensor to determine if and when a shift has been successfully completed. This information is fed back to the ECU so that the pneumatic actuator, engine torque reduction or throttle blip canMore...

Alfaholics Competition Rifle Drilled Halfshaft

Premium quality Alfaholics production. We have developed these new halfshafts as part of our ongoing programme to both increase strength and reduce weight in the drivetrain of 105 Series Alfa Romeos.

New Alfaholics Racing Differential

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 coatingMore...

Alfaholics Premium Quality Synchromesh Rings

New production – exclusive to Alfaholics.  We chose to manufacture these new premium quality synchro rings due to the continuing issues with the reproduction rings currently available on the market.  It is common knowledge among Alfa racers round the world that the reproduction rings are not made to the correct tolerances and this leads to baulked gearchanges and premature molybdenum coating wear, particularly noticeable during track and fast road use.  Until now there has been no solution to the problem, as only the standard reproduction rings have been available. Up until 10 years ago when the genuine Alfa synchro ringsMore...

Alfaholics Premium Quality Synchromesh Sleeve

New production – exclusive to Alfaholics.  We chose to manufacture these new premium quality synchro sleeves due to the availability of new original Alfa synchro sleeves finally ceasing in 2012. When this happened, we tried first to source the already available reproduction sleeves to try them out. When they arrived we noticed an obvious difference in tooth profile which made the rings hard to slide in and out of the sleeves on the bench. During driving, gear baulking, not dissimilar to using the cheap reproduction synchro rings was observed. At this point we knew that we had no option butMore...

Alfaholics GTA Close Ratio Gear Kit

This superb GTA close ratio gear kit has been manufactured exclusively for us by the UK’s leading transmission manufacturer, Quaife Engineering. Unlike any other kit on the market, we have directly copied an original GTA gear kit. As a result, the gears are not only scooped, but they are also drilled for further weight saving, just as original GTA gears. The layshaft is rifle drilled, as original, for further weight reduction. All these weight savings and consequently reduced inertia, result in a gearbox with a lightning fast shift speed both up and down the ratios. Not only does this meanMore...

Alfaholics GTA Close Ratio Gear Kit – REM Superfinished

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.

Alfaholics Race Propshaft Conversion – FRONT ONLY – 105 Series

For years the rubber front propshaft coupling (doughnut) has caused racers huge headaches and retirements from races. Doughnut distortion is caused by high centrifugal forces developed at high speeds. This causes the propshaft bush and gearbox mainshaft ball to wear unevenly and consequently the propshaft spins like a skipping rope and the doughnut itself starts opening out, EVEN when using a GTA doughnut cage. Symptoms range from vibrations which lead to broken clutches and bellhousings, right through to the doughnut exploding which can cause huge damage to the drivetrain and tunnel. We have developed this superb system to eliminate anyMore...

Alfaholics Rear Propshaft Section

Exclusively manufactured for Alfaholics to exacting tolerances. Most rear propshafts have had many UJ changes in their life and as a result can often have damaged UJ housings, this means that even with new UJs vibrations can still occur due to end float in the UJ housings which is beyond shimming out. The sliding joint is also another area for wear on an original unit that of course cannot ever be repaired. As a result of these 2 major factors we no longer use rebuilt rear propshafts in our workshop, fitting only our brand new unit for 100% perfect resultsMore...
