Fits select 1999-2014 Chevrolet, GMC, Buick, Cadillac, Hummer, Isuzu, Pontiac, and Saab vehicles equipped with the 5.3L GM LS engine. This COMP Cams Premium DOD Delete Kit is a comprehensive solution for eliminating the failure-prone Displacement on Demand (DOD/AFM) systems in Gen IV engines, allowing you to convert to a reliable, standard lifter configuration.

This kit provides all the essential components required to complete the conversion and seal the engine correctly after removing the active fuel management hardware. It includes a set of premium non-DOD lifters and new lifter trays to ensure proper valvetrain geometry and longevity. The inclusion of a valley cover, high-quality head gaskets, and torque-to-yield head bolts ensures a factory-grade seal during reassembly.

Fits select 2003-2019 Chrysler 300, Aspen; Dodge Challenger, Charger, Durango, Magnum, Ram 1500/2500/3500; Jeep Commander, Grand Cherokee; and Ram 1500/2500/3500 (Gen III HEMI).

Designed as a high-performance upgrade for Gen III HEMI engines, the COMP Cams Non-MDS Lifter Kit ensures all eight cylinders remain engaged at all times. This kit is a necessary component when deleting the Multi-Displacement System (MDS) or installing performance camshafts that require stable, consistent valve timing. Engineering improvements over standard OE and Hellcat lifters include enhanced oil retention around the axle and roller bearing to minimize wear and extend service life.

The lifter bodies feature strategic reinforcement with extra material at the base to increase stiffness and strength in the critical roller area. This drop-in design protects against roller bearing failure and body breakage in applications ranging from stock rebuilds to high-lift racing setups. Included in this kit are four premium lifter yokes, each designed to hold and perfectly align four lifters for a complete engine set.
