I just got done testing my new pr spring and am very happy with it. This spring will bunp the pressure to 280 psi where I think it needs to be. It is also adjustable at the time of assembly. by that I mean you can raise the pressure with a shim if you are running big power, or if you have 1000 hp we add 2 shims.
Most trucks will only need the spring itself. I have noticed lower pressures on trucks that I did 5 years ago because of spring wearing out from mileage. The pressure shim that we all have been using is no longer enough. Price is cheap for the kit and it comes with a drill bit to expand the ballence hole in the bell housing plate. I think anyone building a trans needs this kit. Under 30 bucks.
I will be using this in every one of my builds.
