Set of (6) Harland Sharp 12V Cummins Billet Steel Rocker Pedestals with 0.750″ shaft. These upgraded bases eliminate rocker pedestal deflection and have been tested to over 6k RPM on PDD’s UCC truck. For customer’s running a WarHead, these upgraded bases also work well to cover up the freeze plug oil leak that occurs when using factory pedestals on a Hamilton War Head. Note, the Cummins/oem rocker arms and pedestals have an approximate 0.745″ shaft diameter, in order to use these upgraded pedestals with oem/Cummins rocker arms, they need to be honed or bored 0.005″ larger. This can be done at home with a small brake hone and coarse stones but it takes several hours. Many of the factory arms have galling and extreme wear so these billet pedestals were designed with an oversized shaft to allow factory arms to be reconditioned and used if you decide to omit the billet roller rocker arms.
