Lunati Pop-Up Lifters For Chevy Small-Block & Big-Block V8’s and V6

Whether it’s at the track or on the dyno, swapping camshafts was a time-consuming process until now. Lunati’s new Horizontal Link-Bar Roller mechanical lifters with “pop-up”, spring-loaded link-bar design appeal to enthusiasts looking for quick and easy camshaft changes without sacrificing important features like weight and durability.

Along with adding the convenience of faster camshaft changes with its pop-up design, the lifters are made from top-notch materials for strength and the professional-quality lifters are some of the lightest available weighing in at less than 200 grams per pair. This lightweight construction further reduces valvetrain weight and increases valvetrain reliability, attributes proven to increase life cycles of all valvetrain components, especially severely stressed racing valve springs.

Lunati Horizontal Link-Bar Roller Lifters feature bodies that are precision machined from aircraft grade steel alloy, then heat treated for strength and wear resistance. Each lifter is hand assembled with premium quality heat-treated steel axles, wheels and needle bearings. Wheels are metallurgically compatible with roller camshaft lobe materials and precisely heat treated to prevent wear and lobe tracking. Installation is a quick and easy, drop-in procedure without block machining.

The lifters are available in .842” outside diameter and current applications include small-block Chevy V-8, Chevy 90-degree V-6 (4.3L) and big-block Chevy, Mark IV, 396-454.
