ARP Pro Series rocker arm studs are ideal for competition applications. They are made from 8470 chromoly steel and are heat-treated to 200,000 psi tensile strength. They are concentric within .005 T.I.R. thread pitch to thread pitch, which will give you more consistent rocker geometry. With an extra-large radius base, these studs are more resistant to flex and will provide a more positive seating. Pro Series rocker arm studs were designed for use with Perma-Loc adjusters (not for use with OEM-style, self-locking nuts).

Rollmaster Red Series timing sets are lightweight and stronger than any other timing sets available, due to the weight savings of billet steel and use of CNC machinery. All sets feature billet steel crank and camshaft sprockets that have been 100 percent CNC-machined for reduced wear and improved accuracy. Rollmaster Red Series timing sets come standard with a premium grade one-piece Iwis full roller chain, produced in Germany and built to the highest possible quality standards. The sets have nine keyways, allowing you more adjustments for dialing in the camshaft to your liking. Multiple keyways are a solid fixture and tend not to move or work loose like offset bushings or dowels--providing a positive locking of the cam timing to whatever position is desired.

The OE rocker arm bearing design is a proven weak link in high-performance LS engines because the bearings are unable to cope with high lift cams, higher valve spring pressures, and sustained high-RPM use. Plus, the uncaptured design allows the needle rollers to be ejected into the crankcase, potentially causing catastrophic engine damage. One way to fix these issues is with a full set of high-quality roller rocker arms. However, many builders prefer the lower cost and lightweight durability of stock rocker bodies. That's where Trick Flow's far less costly solution comes in. The Trick Flow® rocker arm trunnion upgrade kit includes 16 CNC-machined trunnions that are heat-treated and precision ground to tighter tolerances for reduced wear and significantly improved rocker arm control. Precision needle roller bearings withstand high performance cams, valve springs, and repeated high-RPM blasts. They are held captive by extra wide circlips to prevent the bearing walk-out problem of the OE design. The Trick Flow® trunnion installation kit takes all the hassle out of removing old trunnions and installing new ones, with easy installation using just a bench vise instead of a cumbersome hydraulic press like other kits. Best of all, no modification are required to the OE rocker arms to use these upgrade and installation kits! Features Include: • CNC Machined Trunnion - Heat Treated & Precision Ground • Tighter Tolerance & Radial Clearance • Captivated bearing for reliability • Designed for higher stresses and high RPM use • Improved rocker and valve control
