This is a really good internal kit, it comes with everything you need and all the parts are of the highest quality. Right now i run at about 190psi and can get alot of shots off my 68/4500 (not sure of a number), it is also pretty consistant. The hammer is very nice the dual nylocks really make a big difference no more slippage of the rod/lug. Ive had only one problem and that was because i scuffed the cup seal when i installed it but it was a quick fix with the extra seal that was included. If you ever happened to have any type of problem jackal machine will get back to you in a flash, and are willing to do anthing short of driving to your house to get a fix.
