Our High Performance roller rocker arms provide you with almost all the features found in other roller rocker arm kits, but at much lower cost. Roller rockers are a must for Performance motors. Also worth considering when rebuilding a stock or near stock engine as they very much improve valve train efficiency. The roller tips drastically reduce scuffing, valve stem tip wear and galling as they provide full valve stem tip contact. TPD roller rockers are precision investment die-cast from high quality alloy steel and run on factory installed bronze bushings. Use with OEM or stock replacement rocker arm shafts and adjustable push rods.
