I use their 4.15 stroker kit . Raced it since 07. Somewhere around 400 passes or so. No issues yet. Car has went 6.46 in the 1/8 .

I can post some pics of broken rods and cranks from Eagle , Manley , Scat , etc..... does that make those brands all junk ???



whatever brand you use--have it all thourougly checked by a machinist and assemble it yourself making sure to carefully double check everything .

Works for me
