So is the sonnax upgrade a yes or no are there stages or just one?
So harden 4th, 4340 IS, 7/8th chain and shift kit good enough?
Also is this hard to install?
Talk to Dave. He can get you everything you need. I would buy the valve body from him, as well as his 3rd gear upgrade. Hardened 4th would be good as well.
