The TTS POWER Comp is manufactured to be super-strong, utilising a blend of high-quality 655M13/EN36B nickel chromium case-hardened steel. In this hardened state, the part is not only highly wear resistant, but has a super tough core.



This material is similar that used for billet crank shafts and drive gears to name but a few. During testing on our super high-powered supercharged M8 engines, these ramps have survived 250 ft/lb of torque and even catastrophic engine failures, which have placed far more load than normal running.

We have supplied TTS POWER Comps to some of the biggest Harley-Davidson tuners in the world, including Star Racing, Darkside Custom Harleys and the factory Harley-Davidson Race Division.


The best upgrade you can make to an M8 Harley and essential for anyone running power of 140 lb/ft or more.
