600hp 904 parts list

I have done a few, but I am not a expert. But in my experience, I have used the bolt in sprag, A&A aluminum front drum, multi spring kit for the drum,modified the front pump for better flow for the front drum, and the A&A front pump gear set. Good clutches,steels and bands.And proper clearances. The only issue I had was breaking the pump gears in the AMX I drive. The AMX has been 9.90 in the 1/4 mi. at 3200 lbs.
