Restore Factory Reliability: Master 5.3L AFM/DOD Camshaft & Valvetrain Overhaul Kit

Is your Gen 4 LS-based 5.3L engine suffering from the infamous lifter tick, misfires, or excessive valvetrain noise? Designed specifically for GM truck and SUV engines equipped with Active Fuel Management (AFM/DOD), this comprehensive Replacement Overhaul Kit provides everything you need to completely refresh your top-end. This premium master rebuild set is engineered to eliminate annoying valvetrain noise and restore your vehicle to smooth, reliable, factory-spec performance.

Properly servicing an AFM engine requires replacing multiple critical components simultaneously to prevent repeat failures. At the heart of this kit is a precision-machined OE-spec replacement camshaft, paired with a complete set of 8 updated AFM and 8 Non-AFM hydraulic roller lifters. Proper oil pressure is absolutely critical for the AFM system to function, which is why we have specifically included an upgraded high-volume oil pump. To make this a true top-to-bottom refresh, the bundle is fully rounded out with a brand-new water pump, a timing chain kit, premium Multiple Layers Steel (MLS) head gaskets, a complete cylinder head bolt set, an AFM/DOD valley cover gasket, and a front timing cover gasket set.

(⚠️ IMPORTANT INSTALLATION NOTE: This master kit is designed strictly for Gen IV 5.3L V8 engines equipped with Active Fuel Management / Displacement on Demand. Please carefully verify your VIN code and OE interchange numbers before purchasing to ensure proper fitment for your specific vehicle.)

Engineered as the ultimate all-in-one maintenance solution for a massive range of GM 5.3L applications. This master kit flawlessly fits popular trucks like the 2007-2013 Chevy Silverado and GMC Sierra 1500, as well as full-size SUVs including the 2007-2014 Tahoe, Suburban, Avalanche, Yukon, and Yukon XL. It is also fully compatible with 5.3L-equipped 2005-2009 TrailBlazer, Envoy, Saab 9-7x, Buick Rainier, and Isuzu Ascender models. Rebuild your engine the right way with BTSCAR's premium replacement components and get your vehicle back on the road with total confidence.
