TA Performance Rover V8 Roller Rockers

All TA Performance rockers incorporate these key features: 

• 2024-T4 extruded aluminum alloy with a tensile strength equivalent to 75,000 lbs, far stronger than 6061-T6 material used on other rockers that equal only 48,000 lbs.tensile strength.
• 7/16” 8620 steel adjuster screws that have been specially treated and hardened as opposed to breakage prone 3/8” adjusters found on other rockers.
• Torrington bearings on the shaft reduce friction and provide increased durability over bushed rockers.
• 8620 solid steel shafts incorporate a special heat treatment and copper plating method that also incorporates exact tolerance bolt holes which results in the strongest shaft on the market.
• These rockers are .990” wide which is .090” wider than other rockers on the market. The wider rocker allows us to incorporate an internal girdle in the center, between the two shaft bearings. During the manufacturing process the rocker extrusion is first machined to .010” over the shaft diameter, then the rocker is counterbored from each side to accept the Torrington bearings.  This design increases the strength of the arm and allows for additional clearancing of the rocker underside to clear larger O.D. springs.
