Secondary Helix Overdrive Machining

Send us any factory or aftermarket secondary helix and we will machine the inner limit hub to our spec. Also the spring pocket where coil bind can occur. This will give you an additional 5mph on the top end without effecting your low end and mid-range performance whatsoever. Your secondary clutch will shift out fully just like the helix’s in our clutch kits. We highly recommend performing this machining process on your primary clutch as well.
