Streetmax Mechanical Roller Lifters
Typical mechanical roller lifters are not designed for the rigors of street use: on the throttle, off the throttle, constant long periods of idling. Streetmax Mechanical Roller Lifters are perfect for all of these situations. CNC machined alloy bar stock construction with case hardened 8620 rollers ensures long-term reliability and durability.
Sportmax Mechanical Roller Lifters
Sportmax Mechanical Roller Lifters are perfect for the entry level sportsman racer. These budget-priced mechanical roller lifters are constructed from 8620 heat treated steel bodies and topped with 9310 steel rollers. This construction combined with a black oxide finish ensure a long service life.
Sportmax Lite Mechanical Roller Lifters
Sportmax Lite Mechanical Roller Lifters feature the same reliability and durability as the standard Sportmax Lifters, but with machine cuts that lighten the lifters by up to 20 grams.
Trackmax Mechanical Roller Lifters
Trackmax Mechanical Roller Lifters are an excellent choice for racers demanding strength and reliability from their lifters. Each of these lifters is constructed from alloy steel bar stock and 8620 case hardened rollers, with a smooth polished finish.
