Howards Cams Maximum Effort Retrofit Hydraulic Roller Lifters

4.67 out of 5 stars 27 Customer Reviews

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.
