Manton 4130 Hard Chromed Duramax Rocker Shafts 2001-2016New
Todays high RPM Duramax's reek havoc on the OE valvetrain. Increased spring pressures and high lift cams add tremendous stress to the OE rockershaft. DHD recommends upgrading to Mantons 4130 shafts to help limit deflection and breakage. As an added benefit, these ultra strong shafts have improved oiling characteristics for the rocker arm pivot itself, which frees up power and reduces wear tendencies.
Manton Duramax Chromoly 3/8 Performance Pushrod Set 2001-2016 6.6LNew
If your seeking some valve train improvements, Manton has the answers. Manton products are used on many high level builds, including those here at DHD. These 3/8 pushrods are a perfect upgrade for trucks with stock cams and springs.
Features:
3/8" x .095" Wall Thickness
Hard Drawn 4130/4135 seamless chromoly tubing
Billet 86L20 triple tempered tip ends
Includes Oil Hole Provision
Approx. 170,000 psi tensile strength
750HP Rating
STOCK LENGTH Pushrods
Due to the marginal column strength, Manton feels OEM pushrods are not adequate for anything other than a Stock vehicle. When the stress on the pushrod surpasses what is considered a reasonable window of operation, the OEM pushrod is not designed to support the additional load that the valve train system is experiencing .
To provide increased pushrod column strength and valvetrain stability, Manton offers both 3/8 and 7/16 diameter “3 Piece” pushrods. Manton pushrods are manufactured with 4130/4135 seamless Chromoly tubing with a variety of heat treating conditions and wall thickness’ available, all coming standard with their billet steel tip ends. These tips have been CNC machined from 86L20 bar stock that are then core hardened and triple tempered, providing increased impact and wear resistance. This combination of materials and heat treatment procedures will extend the service life of the pushrod, while improving overall performance of your valve train. Manton's versatility in engineering and design allows them to manufacture a product that will enhance the specific combination of your engine.
When they sat down to engineer a pushrod, they always try to fit the largest diameter pushrod they could, within the space available. By increasing the diameter of the tubing from 3/8 to 7/16, the load can be spread over a larger surface area without causing the pushrods to bind with the port of the cylinder head. This larger diameter tubing will provide almost 2 times the loading capacity before the pushrod begins to deflect. Larger diameter is always a better choice when it comes to pushrods and is why we suggest 7/16 diameter in all Duramax engines.

These Billet tool steel Duramax valve bridges replace your mass produced OE bridges with an engineered, high tech, close tolerance bridge thats substantially stronger! These bridges are perfect for you high RPM big power builds.
Available for use with stock rocker arms or Manton Roller Rockers.
This set is for use with Manton Roller Rocker Arms and cannot be used in conjunctions with stock rockers arms
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 of Manton's during the engineering process. Therefore, Manton CNC machines all 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. This combination of materials, precision machining and heat treatment process provides a cost effective solution for reducing friction and extending the service life.
