Manton Billet Tool Steel Valve Bridges

Fits 2001-2016 6.6 Duramax 

Part#D110DMAX

OEM Valve Bridges were originally designed for stress levels that were nowhere near what is being seen in recent years, which has allowed for rocker arm and pushrod issues to arise in performance applications. When the stress on the valve bridge exceeds what is considered a reasonable window of operation, it is not designed to support the additional load that it is experiencing. Therefore, Manton felt it was time to provide the industry with extreme duty valve bridges capable of far more abuse than anything the market has even seen.

Improved strength, performance, and service life are goals during their engineering process. Manton CNC machines their valve bridges from only premium “hot-working” tool steel bar stock. After leaving the milling centers, the valve bridges are all hand inspected before being sent to heat treating for core hardening. Once returned from heat treating, each valve bridge is inspected before having the friction pad surface ground, which removes any tool marks that may cause excessive wear to the rocker arm. Bridges then have their surface nitrided, creating a very slick and hard surface to provide excellent wear protection and reduction of friction. The combination of materials, precision machining and heat treatment process’ provides a cost effective solution for reducing friction and extending the service life.

Last but certainly not least, correct pushrod length will allow you to keep stock rocker geometry, allowing the friction surface of the rocker arm to ride the correct contact area of the valve bridge. If you are unsure if your pushrod length has changed, we recommend checking it with a pushrod length tool.
