Required & Recommended Supporting Parts2 required1 tip
2 required1 tip
ConflictMDS Delete Plugs — Non-MDS lifters require MDS delete plugs to seal the oil passages in the block.
ConflictECU Tuner / Programmer — MDS delete requires a tune to disable MDS operation or the engine will throw codes.
SuggestedCamshaft — Non-MDS lifters are often paired with performance camshafts for maximum benefit.
What Does This Do?
The factory HEMI has MDS (Multi-Displacement System) lifters that can collapse to deactivate 4 cylinders during light driving. These MDS lifters are completely incompatible with aftermarket camshafts — the cam profiles will cause the MDS mechanism to malfunction, leading to lifter failure, collapsed lifters, and engine damage. Non-MDS lifters are solid hydraulic rollers that follow the cam lobe faithfully without any deactivation mechanism. If your Challenger has an automatic transmission, it has MDS and you MUST replace all 16 lifters when installing an aftermarket cam. Manual transmission models already have non-MDS lifters.
