Howards Cams Maximum Effort Retrofit Hydraulic Roller Lifters 91774

Howards Cams Maximum Effort retrofit hydraulic roller lifters are true high performance street lifters designed primarily for ease of maintenance and reliability. The lifters are CNC-machined and then fitted with precision check ball internal valving to prevent lifter “pump up.” These features combine to provide a broader power band and increased rpm potential, while still offering the low maintenance of a hydraulic cam.
