The XDP Street Performance Pushrods (3/8") XD387 will strengthen the weak link in the valvetrain of your 2017-2023 GM 6.6L Duramax L5P. The stock pushrods in your Duramax engine can barely handle stock power levels. With greater cylinder pressure and valve spring pressures from elevated engine RPM, the additional stress can rapidly push the limits of your factory pushrods. Even in lightly modified builds, the OE pushrods can rob you of power from excessive flexing that is not visible to the naked eye. In most cases your pushrods won't show signs of failure before they do, so don't let a bent pushrod cause a complete tear down, upgrade today!

The XDP Street Performance Pushrods (3/8") XD387 are manufactured from seamless 4130/4135 chromoly tube that is cold drawn over a mandrel for superior durability. Each CNC machined tip is constructed from 86L20 bar stock that is triple tempered and core hardened for maximum impact and wear resistance. These additional manufacturing processes produce a pushrod that is more resilient and more reliable than your stock pushrods to help you get the most out of your Duramax. 

Features: 

  • Supports Up To 750HP 
  • 170,000 PSI Tensile Strength 
  • 4130/4135 Chromoly Construction 
  • 3/8" x .095", 8.560" Overall Length
