BTR LS Shaft Rocker Kits

Performance-minded engine builders know there's an inherent issue with valvetrain deflection when using stock rocker arm mounting in Chevrolet Gen III-IV-cylinder heads. BTR LS shaft rocker kits are designed to significantly reduce deflection, thereby improving both performance and durability. Each kit features technology typically only found in high-end shaft rocker systems. These shaft rocker systems consist of a billet steel stand equipped with four shafts per cylinder head, fasteners and bearings. The shafts are made from genuine 52100 bearing steel. Each pair of rockers has five fasteners mounting them to the rocker stand, compared to the traditional single bolt per rocker configuration. These shaft rocker kits are ready for assembly using your existing stock rockers. (Rocker arm shafts are also available individually.)

Moroso Cam Stop Buttons

Professional engine builders are familiar with camshaft walk. Excessive camshaft end play can produce erratic spark timing and the movement of the timing chain/gear can destroy the timing cover. Moroso has solved this problem with a wear resistant cam stop button that mounts in an aluminum holder, which bolts to the cam gear by way of a retaining plate. These button assemblies do not allow the cam to walk forward, stabilizing ignition timing and preventing costly engine damage.

Trick Flow® LS Series Retrofit Trunnion Kits

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
