Alfaholics GTA Close Ratio Gear Kit – REM Superfinished - Transmission - 1300 & 1600 GTA - Alfaholics

Alfaholics GTA Close Ratio Gear Kit – REM Superfinished

£3650.00 GBP (ex vat)


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 Quick Shift Kit - Transmission - 105/115 Series - Alfaholics

Alfaholics Quick Shift Kit

£625.00 GBP (ex vat)


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]

Alfaholics Rear Propshaft – Sprint - Transmission - 750/101 Series Giulietta - Alfaholics

Alfaholics Rear Propshaft – Sprint

£395.00 GBP (ex vat)


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 at virtually no extra cost to the customer. We manufacture these units from race quality thin wall 2” tube, not only does this mean that the tube is stiffer which results in far smoother running at high speeds, but it is also much lighter than an original unit. We have also increased the size of the UJs on each end which makes them much less prone to wear and much more able to handle the load from engines with increased performance. Each prop is dynamically balanced to 8,000rpm meaning that this item is perfect for use on both road and competition cars.
