Permanently Delete AFM: 5.3L Non-AFM Camshaft, Valvetrain & Timing Overhaul Kit
Are you tired of the infamous lifter tick, annoying misfires, and costly valvetrain failures caused by the Active Fuel Management (AFM/DOD) system on your 5.3L engine? Eliminate the problem permanently and restore bulletproof reliability with this complete AFM Delete Overhaul Kit. Designed specifically for Gen 4 LS-based 5.3L truck and SUV engines, this premium package provides the essential components required to properly remove the failure-prone AFM system and upgrade your top-end for smooth, consistent V8 power.
A proper AFM delete requires replacing core valvetrain and timing components, and this rebuild set provides a true mechanical solution. It replaces the factory setup with a reliable standard Non-AFM Performance Camshaft (Specs: 199/191 @.050", .466"/.457" Lift, 114 LSA, 1-Bolt) and a full set of 16 standard hydraulic roller lifters with trays. To complete the mechanical conversion, we've included an AFM/DOD delete valley cover gasket, a 1-bolt engine timing chain kit with sprockets, and a camshaft thrust plate. To guarantee a perfect seal during reassembly, the bundle is rounded out with premium Multiple Layers Steel (MLS) head gaskets, a brand-new complete cylinder head bolt set, and a front timing cover gasket and seal kit.
(⚠️ IMPORTANT INSTALLATION NOTE: This specific kit does NOT include an oil pump or water pump. It is designed specifically to mechanically delete the Active Fuel Management / Displacement on Demand system. Professional custom ECU tuning is STRICTLY REQUIRED after installation to electronically disable the AFM system and prevent check engine lights or drivability issues.)
Engineered as the ultimate valvetrain fix for a massive range of GM 5.3L applications. This kit flawlessly fits popular trucks like the 2005-2013 Chevy Silverado 1500 and GMC Sierra 1500, as well as full-size SUVs including the 2007-2014 Tahoe, Suburban, Avalanche, Yukon, and Yukon XL. It is also compatible with 5.3L-equipped TrailBlazer, Envoy, Saab 9-7x, Buick Rainier, and Isuzu Ascender models. Bulletproof your LS engine the right way with BTSCAR's premium replacement components and drive with total confidence.
