Permanently Delete AFM/DOD: Complete Non-AFM Camshaft & Lifter Overhaul Kit for GM Gen IV 5.3L V8
Are you tired of worrying about the notorious Active Fuel Management (AFM) or Displacement on Demand (DOD) lifter failures on your GM Gen IV 5.3L V8? Collapsed AFM lifters are a widespread, catastrophic issue that can quickly destroy your camshaft, cause severe engine misfires, and lead to costly repairs. Eliminate the problematic AFM system entirely and restore bulletproof, reliable V8 performance with this essential AFM Delete Overhaul Kit. Designed specifically for Gen IV LS-based 5.3L truck and SUV engines, this focused package provides the exact core components you need to safely bypass the DOD system and upgrade your valvetrain to a traditional, highly durable non-AFM setup.
Sourcing a properly matched non-AFM camshaft, standard hydraulic roller lifters, and the necessary block-off plates separately can be a massive headache. This comprehensive rebuild kit takes the guesswork out of your AFM delete project. It features a reliable standard non-AFM 1-bolt camshaft, a full set of 16 standard lifters, and a custom aluminum AFM/DOD delete valley cover pan to seal off the active fuel management oil galleys. Combined with premium Multiple Layers Steel (MLS) head gaskets and new Gen IV equal-length cylinder head bolts, this kit ensures a permanent fix to the GM lifter tick.
Key Features & Included Components:
Non-AFM Performance Camshaft: Includes a 1-Bolt standard non-AFM camshaft (Specs: 199/191 @.050", .466"/.457" Lift, 114 LSA) designed to restore smooth, consistent, and reliable engine power without the risk of AFM failure.
Complete Lifter & Valley Cover Upgrade: Features 16x standard non-AFM hydraulic roller lifters paired with 4x guide trays, plus a dedicated aluminum AFM/DOD delete valley cover pan (with gasket) to properly block off the system.
Premium Top-End Sealing: Comes with Left and Right Multiple Layers Steel (MLS) head gaskets, valve cover gaskets, premium valve stem seals, and a complete timing cover gasket & overhaul seal kit.
Critical Installation Hardware: Includes a complete set of Gen IV equal-length cylinder head bolts, a camshaft thrust plate, and a brand-new harmonic balancer bolt (a mandatory Torque-to-Yield single-use fastener).
(⚠️ CRITICAL FITMENT & INSTALLATION NOTE: This kit is designed for Gen IV LS-based 5.3L truck and SUV engines. Please note that the Oil Pump, Water Pump, and Timing Chain are NOT included in this kit. Custom ECU tuning/programming is ABSOLUTELY REQUIRED after installation to electronically disable the AFM/DOD system and prevent Check Engine Lights (CEL) or limp mode.)
Engineered to meet or exceed strict OEM specifications for long-lasting, reliable performance. Delete your problematic AFM system the right way with BTSCAR's premium replacement components and drive your truck with absolute peace of mind.
