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.)

COMP Cams Ultra Pro Magnum Rocker Arms

Utilizing years of valvetrain design experience, the latest FEA stress analysis technology, and an exhaustive testing regiment (dyno and Spintron), COMP Cams engineering team left no detail to chance. Everything from casting techniques to valve spring clearance was scrutinized to ensure that Ultra Pro Magnum rocker arms not only lived up to the lofty standards of their predecessor, but also took stud mount rocker performance, stability, and value to a whole new level. The most noticeable advancement centers around their nearly unbreakable investment cast 8650 chromoly body. The arched, web-like design delivers a nearly 29 percent increase in strength and rigidity, while reducing the moment of inertia and optimizing the dynamic balance. The resulting rockers maximize lift and valvetrain control at high rpm. The increased retainer and valve spring clearances of the new design enable the use of large-diameter valve springs, retainers, and locks, without clearance or fitment issues. The new black oxide exterior finish offers a distinctive appearance, along with long-term corrosion resistance. The COMP Cams Ultra Pro Magnum rocker arms feature an oversized trunnion and precision-sorted needle bearings designed for use with high-load valve springs. These unique rockers also feature hardened roller tips for reduced friction and elimination of the valve stem "side loading" that causes premature valve guide wear.

COMP Cams XFI SPR GM Gen IV VVT Camshafts

Rather than find ways around the recent advances in GM engine technology, the engineers at COMP Cams have found a way to work with the innovations to produce a powerful line of cams for newer L92 engines. These COMP Cams XFI SPR GM Gen IV VVT camshafts feature four unique cam grinds that provide substantial gains in both torque and horsepower. The 2007 and later GM L92 engines utilize Variable Valve Timing (VVT) technology, which changes the timing of the valves while the engine is in operation. VVT is controlled via cam phasers, which are computer-controlled cam gears that automatically optimize camshaft timing based on current engine rpm. While this technology provides tremendous efficiency benefits, it presents a challenge when designing performance camshafts. This is due to the wide range of the valve timing movement, which causes piston-to-valve clearance. Using the COMP Cams cam phaser limiter kit restricts the range of cam timing movement from 50 degrees to 20 degrees. While still utilizing the efficiency benefits of the VVT technology, this modification provides the necessary valve clearance for larger, more serious performance camshafts with tighter lobe separations.
