The XDP 3/8 inch Street Performance Pushrods XD387 will strengthen the weak link in the valvetrain of your 2017-2020 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 3/8 inch Street Performance Pushrods 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 inch x .095 inch, 8.560 inch Overall Length

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
