Alfaholics GTA Close Ratio Gear Kit
Prices are exclusive of VAT.
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 mean a sweeter and more positive shift action, but on track a saving of several tenths of a second over a lap. This is a must for all racers!
We have considerable experience in using other aftermarket gear kits which feature full needle roller bearings on the mainshaft gears. These have proved to be fragile and we have suffered a number of failures. As a result, the Alfaholics GTA gears have been specially developed in conjunction with Quaife to feature partial needle roller bearings for reduced friction and part bronze bush to maximise strength in the gear. The tooth profile has also been improved from original to further increase the torque and power handling capacity of the box. As a result of these improvements in design, the Alfaholics GTA gear kit is not only the lightest kit on the market, but is also the strongest. The synchro dog teeth have been specifically cut to match original Alfa items so the gearbox can be built using original Alfa synchro hubs and rings. Ratios are as per original GTA Corsa but with a 0.85 5th gear, the best ratio for track use. The kit has also been designed so that 5th gear is interchangeable with original, so 0.79 and 0.88 ratios can be fitted instead if necessary.
As used in the Alfaholics 2.0 Sprint GT Racer.
