DHD 007-6010 Duramax PCV Valve Cover Kit 2006-2010 LBZ LMM Large Pattern

Finish your Duramax engine build or PCV reroute off with this billet PCV Valve Cover Kit from DHD. Our billet covers are designed to replace those rusty stamped covers and phillips screws. Each cover is milled to accept the OE diaphragm and utilizes new stainless M5 Hardware. This cover set is designed to fit the larger bolt pattern cover typically found on LBZ and LMM trucks. Unfortunately, exact application data is limited due to valve cover variations used in production. We do not currently have access to the diaphragm for under this cover. GM does not service it separately. The bolt pattern on this cover is 1.5" x 1.5". If your cover bolt pattern measures 1.325" x 1.325" you'll need DHD 007-0410.

Features:

• 1/2" Thick Billet Aluminum
• Black Anodized Finish
• Stainless M5 Hardware Included
• Works in Conjunction with OE Diaphragm
• Promotes Better Sealing
• Made in the U.S.A

Note: Due to some variations in valve cover years and applications, please confirm your cover bolt pattern is approx 1-1/2" x 1-1/2" square.
