Product Information

Full set of components required to rebuild all moly-synchro type 105/115 series gearboxes. Available as “Early” for Cable Clutch Cars or “Late” for Hydraulic Clutch Cars.
Both kits are available as either ‘OEM’ using original quality synchro rings or ‘Competition’ which uses the Alfaholics synchro rings with a modified profile for faster shifting and greatly reduced bed-in period as suited for racing use.
When ordering the Late/Hydraulic version, please check the internal diameter of the front layshaft bearing as these changed from 25m to 20mm for cars with the 2000 engine and some subsequent post 1972 models. As some cars will no longer be running their original gearbox we advise you to check this diameter in case of a previous gearbox change.
Please note that these kits are not suitable for early Cable clutch gearboxes which use non-molybdenum synchromesh rings. These gearboxes are identified with a YELLOW sticker advising the oil type to be used so you will also need this conversion package if you are rebuilding that type of gearbox.
If your Cable type gearbox has the RED oil sticker you can use this kit.
If you have no sticker, then check your synchro rings, the moly type have a rough finish, the non-moly type have a smooth finish with distinct grooves.
