Description

The RD2FS IPR securing spacer nut upgrade is an American-made component designed to resolve issues with the Injection Pressure Regulator (IPR) on 7.3L Powerstroke, T444E, DT466/E, 530/HT530/I530E engines. This patented part addresses stalling, no-start conditions, and surging ICP pressure by preventing the Tinnerman nut and spacer from vibrating loose. It offers significantly more thread engagement and surface area, a doubled torque specification without stripping, and allows for the addition of Loctite.
