Description

The P2R J Series WPC Treated Rocker Shafts provide a complete replacement set for your engine's intake and exhaust rocker arms. WPC treatment is a proprietary process that has been employed in the automotive and racing industries for years. Unlike a coating, WPC is a surface enhancement that works to reduce friction and increase the strength of metal engine parts. This treatment can lead to improved engine performance and longevity. This set of rocker arm shafts is compatible with a wide range of J Series engines, including those with the following engine codes: J30A1, J30A4, J30A5, J32A1, J32A2, J32A3, J35A3, J35A4, J35A5, J35A6, J35A8, J35A9, and the J37A1 (specifically for 08-09 models only).
