Description
Has the Displacement on Demand (DOD) or Active Fuel Management (AFM) system started ticking, sticking, or outright failed on your 2007–2013 GM 6.0L or 6.2L truck or SUV? Common signs like a collapsed lifter, persistent top-end valvetrain tap, or misfire codes are classic symptoms of AFM component failure. This SDPC direct-replacement repair kit restores factory functionality and valvetrain geometry without requiring aftermarket PCM tuning or software modification. Designed specifically for Gen IV 6.0L (L76, L77) and 6.2L (L94) platforms, this complete service package equips you with genuine factory hardware to repair collapsed lifters and worn camshaft lobes properly the first time.
Tech Tip: We strongly recommend replacing the Valve Lifter Oil Manifold (VLOM) valley cover during this service. The internal solenoids and fine oil screen inside the factory VLOM are frequent culprits behind low oil pressure delivery to the AFM towers, which directly triggers lifter collapse. You can easily add a brand-new updated GM VLOM assembly via the dropdown menu.

Key Kit Features & Service Benefits:
- Factory Restoration: Restores original engine operation and cylinder deactivation efficiency without needing PCM recalibration, handheld tuners, or emissions defeat devices.
- Complete Top-End Hardware: Includes all necessary GM MLS head gaskets, multi-layer exhaust gaskets, and replacement TTY head bolts required to reseal the top end to factory specifications.
- Fresh Camshaft & Lifters: Replacing the damaged AFM lifters along with a matching factory camshaft ensures correct valve timing and prevents premature wear caused by scarred or pitted original lobes.
- Upgraded Lifter Trays: Fresh lifter guides prevent lifters from turning in their bores, preventing catastrophic roller failure.
- Recommended VLOM Replacement: Contaminated or sticky oil control solenoids inside the factory valley cover are a leading cause of recurring lifter failure—adding the updated GM VLOM ensures clean, consistent oil pressure to new lifters.
