Mechanics and DIYers working on Chrysler, Jeep, or Dodge vehicles, this non-MDS lifter set is exactly what you need for those troublesome Hemi engines! These replacements work with 5.7L, 6.1L, and 6.2L engines across multiple models and years. They're direct replacements for OEM part numbers 53021720AA, 53021720AD, 53021720AE and several others. If you're dealing with that classic lifter tick or worse - collapsed lifters damaging your camshaft - this set will get your engine running quietly and smoothly again. The non-MDS design is crucial for eliminating the failure points that plague the factory MDS lifters. Fitment includes Challengers, Chargers, Rams, Grand Cherokees, Chrysler 300s, and Magnums from 2006 up to 2021 depending on the model. Installation requires mechanical knowledge and typically involves removing the intake manifold and valve covers, but if you're tackling lifter replacement, you probably know what you're doing. Quality feels solid and comparable to OEM, but without the MDS system weaknesses. Definitely cheaper than dealership parts and can save you from more expensive engine damage down the road. If your Hemi is making noise or you're doing preventative maintenance, this lifter set is the right solution.
