What it does
The PR valve has an upgraded seatless design. The kit addresses over-pressurization, which causes major 1-2-3-4 and 35R drum and piston cracking, by lowering failsafe/brown-out max line pressure to 285PSI to help prevent high pressure parts from breaking.
It also improves TCC apply, lube and pressure regulation stabilization.
