Howards Cams Street series retrofit hydraulic roller lifters are designed for street performance enthusiasts who want to upgrade to a hydraulic roller camshaft.

The lifters are then carbonitrided and tempered for hardness. They also feature hardened and tempered steel alloy roller wheels, heat-treated stainless steel cross bars, and high-alloy steel tie bar buttons. Howards Cams Street series retrofit hydraulic roller lifters are made in the USA and are specifically designed for street applications up to 6,500 rpm
