T&D Viper V-10 Rocker Arms

Features & Benefits of T&D shaft-mount roller rocker systems T&D rocker arms have an oil passage (see diagram) built into most rocker arms to channel pressurized oil from the pushrod cup to the shaft bearings and then on to the roller tip. T&D's 7/16” adjuster screw and heat-treated alloy steel jam nut are the largest in the industry, giving more thread contact area to positively secure lash settings. Each adjuster is broached for a big 3/16" socket to eliminate twisted hex keys. T&D’s larger diameter shafts are made from 4130 steel, deep case hardened and tempered for maximum wear resistance and strength. T&D aluminum rocker bodies use 2024 aluminum made to our specifications for improved tensile and yield strength, and increased notch sensitivity, fatigue resistance, strength at elevated temperatures and chemical resistance. T&D has gone to great lengths to find the right material to use in its steel rocker bodies, which remains proprietary. Extensive R&D, and constant hands-on usage, has given T&D a distinct advantage in the area of steel rocker development.
