Features:

The Manton I-Beam Rocker Arm is designed to deliver superior strength, stiffness, stability, and reliability, making it ideal for high-abuse applications. Drawing inspiration from historical designs, the I-Beam configuration ensures unmatched strength and stiffness, a principle evident in structures like bridges and buildings.

Highest Strength-to-Weight Ratio:

Our roller tip I-Beam rocker arm boasts the highest strength-to-weight ratio among rocker arm designs. Manufactured from the highest-grade Billet steel and heat-treated for enhanced properties, each rocker arm is built for durability. The nitride Tool Steel rocker arm shaft further minimizes the risk of breakage.

Advanced Bushing Design:

Featuring a high-load bushing with pressurized oiling, our rocker arm ensures optimal lubrication. Oil flows from the lifters through the pushrod to the adjusting screw, distributing evenly through the rocker arm bushing. This fully bushed design, free of needle bearings, offers advantages like higher load capacity, reduced friction, better oil control, and improved spring stability. The use of shim washers allows for precise roller-to-valve alignment and oil spillage adjustment to meet specific engine needs.

Enhanced Load Capacity:

We’ve increased the loading area for both the pushrod and roller interface to withstand higher abuse and RPMs. Our 3/8 ball adjusting screws, used in Top Fuel and Blown Alcohol applications, outperform traditional 5/16 cups by providing better oil retention and reducing wear during startup. The larger .571″ roller wheel with a .275″ pin accommodates higher engine speeds and cylinder pressures, proving its durability in extreme conditions.

Direct Replacement Compatibility:

The Manton billet rocker arms can be used as direct replacements for T&D or Crower rocker arms of the same ratio, fitting directly onto their stands.

Upgrade to Manton I-Beam Rocker Arms for unparalleled performance and reliability in your high-abuse engine applications.
