Titan rockers are the ones all others are compared to and are considered the best available.
Full roller rockers create less friction at the shaft compared to bushed rockers and due to the roller tip, put less side force on the valves, increasing valve stem and valve guide life. High lift rockers will generally give horsepower increase above 4000 RPM. We recommend checking piston-to-valve clearance, valve spring coil bind, push rod clearance, and rocker pedestal hardware clearance when this product is used with high-lift cams.
Complete kit includes aerospace-quality machined aluminum rockers, adjuster hardware, steel pedestals, rocker spacers, and heavy-duty, thick wall shaft. Fits all 1275 engines.
