A short travel aftermarket hydraulic lifter with axle oiling for the HEMI that is designed for the high boost, high horsepower application.
If you currently have MDS (Cylinder Shut Down) and are switching to these non-mds lifters in order to remove the OE MDS-Lifters which cannot support the larger camshafts and will collapse under the higher loads you will need to turn off the MDS operation in your calibration.
**These Lifters will typically require different pushrods lengths than stock, we recommend a pushrod measuring tool like the MSRC-GEN 3 HEMI **
These lifters from Johnson are non-MDS and will work as a direct replacement in any Gen 3 HEMI engine application.
