These ain’t your grandma’s lifters. The Johnson Short Travel Non-MDS Hydraulic Lifters are purpose-built for Gen 3 HEMI engines living the high-boost, high-horsepower lifestyle. If your engine’s more “hold my beer” than “factory spec,” you’re gonna need these.
First off, let’s kill the drama—literally. These are non-MDS lifters, meaning no more cylinder deactivation nonsense getting in the way of your spicy cam setup. If you’re pulling out those factory MDS lifters (which tend to cry under pressure and collapse when things get gnarly), you’ll want to disable MDS in your ECU calibration. No shortcuts—your tuner will thank you.
These Johnson lifters feature a .195″ shorter pushrod cup height, giving them a total travel of .143″. Translation: tighter valvetrain control and fewer chances of valve float when you’re screaming toward redline like it’s going out of style.
They’re designed to work with most Gen 3 HEMI platforms and will likely require custom pushrod lengths—so grab a pushrod length checker like the MSRC-GEN 3 HEMI tool and measure like you mean it.
Recommended preload is:
.035″ ± .010″ (for standard versions)
.035″ ± .005″ (for short travel versions)
And for those running aluminum blocks? Go long on preload—you’ll lose .012″ to .015″ just from expansion. Ain’t science fun?
Bottom line: these lifters are the strong, silent type—no ticking, no collapsing, just reliable valvetrain performance that’s ready to rage. Bolt ‘em in, rev it up, and let your HEMI eat.
THESE DO NOT COME WITH TRAYS. YOU WILL NEED TO GET NEW NON-MDS TRAYS.
