View Details Description
The XDP HD Billet Rocker Arm Valve Bridge Set XD384 will greatly improve the factory valvetrain in your modified 2001-2023 GM 6.6L Duramax. The OE rocker arm bridges in your valvetrain were designed for stock output levels. Once modified, your Duramax engine can quickly produce more stress and load than the factory rocker arm bridges were made to handle. The XDP rocker arm bridges are CNC-machined out of hardened 4140 chromoly for extreme strength. Each set is then Nitride coated to minimize friction and provide added protection. Sold as a set.
Features:
- Nitride Coating
- Sold As Complete Set
- Billet 4140 Chromoly Construction
Application Note:
Designed for stock rocker arms only.
Will not work with aftermarket rocker arms.
Warranty Info:
Products manufactured by XDP carry a 1-Year warranty against defects in materials and craftsmanship. The Warranty is Limited to one (1) year from the date of sale and limited solely to the parts contained within the product's kit. Click Here for full warranty policy.

DURAMAXTERS OF S FLORIDA (JENSEN BEACH, FL) | August 15th, 2023
Installed on a 250,000 + mile LB7 pushing the limits on a stock bottom end (roughly 750 - 800 crank/horses). Installed PPE cast iron heads part# 110100101, XDP Billet Rocker Arm Valve Bridge Set XD384, and XDP 7/16 Competition and Race Performance Pushrods #XD316. All of these parts are held by ARP Fasteners. The combo resulted in a very stable and vibration free upper end, and in more responsive top end acceleration.
