PROFORM’s Super-Street Roller Rockers are for serious street performers and weekend-warrior racers looking to unleash the horsepower of their LS Gen III/IV V8 engines. Built to accommodate high-performance valve springs, up to 750 lbs., these rockers are constructed from aircraft-grade 6061-T6 aluminum that has a high chromium content that is resistant to corrosion, increases tensile strength, and weighs less than standard stainless steel.
The pedestal mounting system dramatically improves high-rpm performance and better stabilizes the valvetrain allowing for full lift. Their stud mount counterparts can lose up to 10 horsepower (if not using stud girdles), due to their erratic flexing at mid-to-high rpm ranges.
The precision machined 1.7 ratio arms feature heavy-duty, precision-ground trunnions, enhanced full-cage bearings and steel full roller tips for reducing friction. An internal oiling system keeps the moving parts of the head lubricated by redirecting oil pumped up from the pushrods. Finally, they are engraved with the ratio number and PROFORM “P” logo in the deep blue anodized finish of each arm. Each set includes 16 roller rockers, 16 pedestals, and 16 M8 Allen-head mounting bolts.
