D&J Precision Machine 03-05 Dodge Cummins Billet Valve Cover

Introducing our in-house designed 03-05 Cummins billet valve cover, balancing fit, finish, functionality, and budget. 

Superior Construction

• Material: Made from aircraft-quality 6061-T6 aluminum for exceptional durability and strength.
• Fasteners: Comes with all stainless steel fasteners to ensure longevity and resistance to corrosion.

Advanced Baffle System

• Design: Incorporates a highly effective baffle system, extensively tested to minimize blow-by. For engines without excessive blow-by, a catch can is not required.

Custom Breather and Hose

• Included Accessories: Features our custom billet breather and a 3/4-inch hose to maintain affordability.
• Fittings: AN style fittings are available at an additional cost. The breather is threaded for a -16 o-ring fitting, allowing you to use your own fittings and hose if preferred.

Enhanced Aesthetic and Practicality

• Oil Cap: We have chosen to reuse your stock oil cap, complemented by a billet cover to enhance the overall appearance. This approach avoids the common issues associated with fully billet caps, such as excessive tightening, loosening, and high temperatures during engine operation.

Key Specifications

• Material: Billet Aircraft Quality 6061-T6 Aluminum
