The Web CAMS 813S grind is the maximum lift available using stock buckets and shims, these cams are considered the best top end performing street cam for the Hinckley Triumph air cooled twins including the bigger bore engines. To compliment these cams or if you want a significant increase right across the rev range please see our listing for 904cc Big Bore kit with 12:1 compression racing pistons and Nikasil cyclinders.

We currently have three cam profiles available, 813S grind described above, the hottest street cam for the 360 degree Bonneville and Thruxton and also the early high lift 790 cams for both the 360 and 270 degree engines, all 790 and 865 carb or EFI Bonneville, Thruxton, America, SpeedMaster and Scrambler, in some cases the increase in lift is significant between the older 790 cams and the later 865 EFI cams, all of these cams can be used without clearance issues with stock factory Triumph pistons, stock head gaskets and cylinder heads or blocks that have not been milled, also with the TTP 904cc 12:1 compression big bore kit. TTP have specific tunes for your chosen exhaust system, intake mods and these performance camshafts.

The service is based on core exchange, you send us your cams in perfect condition and we will return them after they have been hard weld and ground to the new profile, typical turn around time is 2-3 weeks, note that your cams will be inspected before being accepted.
