PRW Sportsman Steel Roller Tip Rocker Arms
PRW Sportsman steel roller tip rocker arms are an ideal choice for a significant cross-section of engines. Anything from a mild street rebuild to the performance demands of off-track, Circle Track, and drag racing. These 4340 chromoly steel rocker bodies feature a longer pivot slot for higher lift camshafts. They're much stronger than stamped steel, so rocker arm flex is negligible. The roller tip minimizes scrubbing from the valve stem pushing forcefully against the valve guide. This reduces friction and frees up an additional 15 to 30 hp over stock models. PRW Sportsman steel roller tip rocker arms are an excellent performance alternative to stock rockers. Order the set recommended for your specific vehicle and engine size. Features, items, and specs: * Wide assortment of ratios to suit almost any cam profile * PRW RockerLocs * Rated at 350 lbs. open spring pressure * Heat-treated pivot balls
