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 [more]

Developed exclusively in conjunction with the UK's leading motorsport transmission specialists, Quaife Engineering. This kit is a direct fit to all 105 series Alfa Romeos and uses the original bellhousing and clutch set up. We have a developed a bespoke gear ratio set with a 2.4:1 first gear, running through to a 0.889:1 6th gear, with the result that there is no need to change the standard Alfa rear axle ratio. Other ratio sets are available by special order. The kit is supplied as standard with a gearlever for manual shifting. An optional ECU-controlled semi-automatic paddle shift system is available...

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 can...

New premium quality Alfaholics production, manufactured in the UK to the very highest quality and exacting tolerances. We have taken the opportunity to improve the tooth cut profile for increased strength over the original cut used by Alfa. These crown wheel and pinion sets are available in the small 1300/1600/1750 size in 5.8, 5.3 & 4.3 ratios. Optimum performance can be achieved by fitting in conjunction with our Alfaholics Limited Slip 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 coating...

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 rings...

Premium quality Alfaholics production. Internal synchro strap for 1st gear, 1 required. We have made these to replace the often damaged part found fitted inside the synchro assembly. Typically these just get reused each time the gearboxes get rebuilt, but they are now getting to an age where these are simply damaged and will not allow the synchro to operate as it should.

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 but...

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.

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 results...

The UJs are also scalloped for additional weight saving. Once manufactured, the entire unit is balanced to 10,000rpm to ensure perfect balance at all speeds that it will experience in use. It is worth remembering that all 105 series gearboxes run an overdrive 5th gear so the propshaft can spin somewhat faster than engine speed! Those with experience...
