Solid Mechanical Roller Lifters

Alan Roehrich · 02-09-2017, 11:34 PM

Most people seem to find that the bushed lifters do not make as much power. Not sure why.

Use a premium quality lifter, the biggest body and the biggest wheel that will fit the engine and the rules, with pressurized oiling. Have them rebuilt no less than once a year.

Do not use restrictors. Possibly the biggest contributor to lifter failure is loss of control in the valvetrain, which isn't always readily apparent. You may not see any other symptoms, but if you're hurting good lifters that have adequate oil (quality AND quantity) and proper maintenance, then odds are good that you have a control problem. Too little spring will hurt lifters far faster than too much.
