It is just a stage 2 I believe. It's been awhile honestly and I was still in high school when I had it put in. Probably 4 or 5 years. It always held well though, I was very particular during the break in and only really launched it a handful of times. No sense on during a hard launch every time you give someone a ride, they are just as impressed if you get rolling at like 5mph then romp on it.
