The XDP HD Billet Rocker Arm Valve Bridge Set XD384 will greatly improve the factory valvetrain in your modified GM 6.6L Duramax LB7/LLY/LBZ/LMM/LML/L5P. 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.
Manufacturer Warranty*:
2 Year / Unlimited Mileage
