Permanently Delete AFM: Essential 5.3L Non-AFM Camshaft & Lifter 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 V8 reliability with this essential AFM Delete Overhaul Kit. Designed specifically for Gen 4 LS-based 5.3L truck and SUV engines, this focused package provides the core mechanical components necessary to properly remove the failure-prone AFM system and upgrade your valvetrain to a durable, traditional 3-bolt setup.
A proper AFM delete requires replacing specific core valvetrain parts to achieve a true mechanical conversion. This tailored rebuild set replaces the problematic factory setup with a highly reliable standard Non-AFM Performance Camshaft (Specs: 199/191 @.050", .466"/.457" Lift, 114 LSA, 3-Bolt) alongside a full set of 16 standard, non-AFM hydraulic roller lifters with trays. To complete the core mechanical bypass, we've included a dedicated AFM/DOD delete valley cover (complete with gasket and bolts), a camshaft thrust plate, a crankshaft/camshaft retainer bolt, and a front timing cover gasket and seal kit.
(⚠️ IMPORTANT INSTALLATION NOTE: This is a focused core kit that does NOT include cylinder head gaskets, a timing chain set, or valve springs. 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 definitive core 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.
