Hi-Tech .120" Wall pushrods for GM 6.6L Duramax Diesel 2001-2016 - Set of 16

The three-piece Pushrod design allows for two different materials to be used - one for the tubing and another for the tips. Heat-treated 4130 was selected for the tubing due to its excellent compressive strength and strength-to-weight ratio. The tips are CNC-machined from 86L20 for incredible wear resistance due to its toughness. Each pushrod features a 12mm ball top end and 12mm bottom cup end with oiling holes - perfect matches to the OEM design that will allow these pushrods to work perfectly with stock or upgraded valve train components.
