ICT Billet DFM DOD Delete Plug Kits

ICT Billet DFM DOD delete plug kits contain performance parts for newer GM Gen 5 L84/L87 5.3L/6.2L engines (2019+). They eliminate the factory Dynamic Fuel Management (DFM) system by plugging the oil passages in the engine block. This allows for a traditional lifter setup, better performance, and consistent cylinder firing by removing the complex solenoid system—requiring an ECU tune to disable the DFM function. What it does: * Blocks oil passages: The kit contains aerospace-grade billet aluminum plugs (and hardware) that physically seal the holes in the engine block where the DFM solenoids once were * Replaces DFM/DOD: It allows you to convert from DFM (and the older DOD/AFM systems) to a standard lifter and camshaft setup, eliminating potential failures and improving reliability * Improves performance: By ensuring all cylinders are always active, it restores smooth throttle response and consistent power * Required when using a DOD camshaft to plug the bores in the engine block under the valley cover * Compatible with L84 and L87 engines only * Compatible with Gen V, LT series engines Key components: * 8 billet aluminum plugs * 16 O-rings, 8 clamps and bolts for installation When you need it: * When installing a performance camshaft * To fix or prevent DFM/DOD system failure. * To optimize performance and reliability on L84/L87 engines

Crown Automotive Multiple Displacement Solenoids

Crown Automotive offers replacement solenoids for a vehicle's Multiple Displacement System (MDS). The solenoids are electro-hydraulic valves that control the oil pressure needed to deactivate cylinders in engines like the 5.7L and 6.4L HEMI V8 for improved fuel economy. These parts are manufactured from factory materials and specifications to ensure proper fitment and performance. They meet or exceed OE quality standards. Product function and purpose: * Controls oil pressure: The solenoid's primary function is to control the flow of oil to the engine's lifters * Activates/deactivates cylinders: When activated, it sends pressurized oil to collapse the lifters on the specified cylinders (like cylinders 1, 4, 6, and 7), which keeps their valves from opening and effectively shuts down the cylinder * Improves fuel economy: By deactivating cylinders, the system allows the engine to operate as a more fuel-efficient V4 under light load conditions * Ensures proper operation: A functioning solenoid is crucial for the MDS to work correctly, which is essential for both power and fuel efficiency
