Alfaholics Premium Quality Synchromesh Ring
£110.00 GBP (ex vat)
RCE6008/5
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...
Synchro Ring

GRB003
Standard quality. For trackday and competition cars we recommend using our own premium quality production above this listing.
Alfaholics Premium Quality Synchromesh Sleeve
£140.00 GBP (ex vat)
RCE6008/6
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...

Alfaholics Race Selector Rod For 3rd/4th Gear
£275.00 GBP (ex vat)
SROD34L
3rd/4th gear selector rod is an inherently weak part in the gearbox, the narrow width required as part of the gearbox design means that the clevis where the gear linkage drops into can easily get bent from ‘over-selecting’ gears. This risks a shift not fully selecting a gear and resultant massive gearbox damage. We have re-designed the part with greater radiuses and increased material thickness at the weak points and manufactured them from billet motorsport grade steel to make the part more resilient to this ‘over-selection’ based driver damage.
Alfaholics GTA-R Steel Selector Fork Set
£975.00 GBP (ex vat)
SRSFSET
Worn/damaged selector forks are becoming a bigger and bigger issue with Alfa gearboxes as they get older and increased performance & race use is highlighting the inherent design weaknesses of the standard parts. We have redesigned and manufactured these race quality forks by combining our considerable experience of high performance & motorsport use along with general modern motorsport knowledge to produce the ultimate selector fork set of 105/115 series gearboxes. We have added an additional pressure pad to control the synchro sleeve angle more accurately and to increase the total pad area and thus reduce pad wear rate, the net result is a sweeter and faster shift action. These forks are made of motorsport grade steel, so are also more resilient to abuse from over selecting than the factory bronze parts. As developed for and being used in our latest GTA-R builds.

Alfaholics Rear Propshaft Section
£395.00 GBP (ex vat)
GRB102/1
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...
