We're expanding our Max Output series into three variations; Max Output I, II & III

This kit is from our Max Output II series.

It sports a custom made high output drop in spring with increased seat and open pressures as well as a full .600" lift range.

This kit fills a void in drop in springs, it offers dual spring pressures all in a drop in design- No need to machine the heads.

Perfect for engines calling for higher spring loads.

This Max Output II kit works with cams w/ up to .600" lift and up to around 250 degrees duration @ .050" (not to be confused with advertised duration which is always a higher number, use the duration @ .050" figure)

For those who love the cackle of a thumping cam, we've got you covered!
