Product Advantages
This all-in-one top & bottom end repair kit is specially designed to permanently delete GM Gen4 5.3L factory AFM/DOD cylinder deactivation system. The Non-AFM camshaft and solid lifters eliminate common AFM failures: lifter collapse, loud tick noise, rough idle, misfire and excessive oil consumption, delivering consistent full-cylinder power output.
- M295HV upgraded oil pump maintains stable oil pressure to protect crankshaft, rods and valve train
- Complete timing chain kit with reinforced gears solves timing stretch and cold start rattling
- MLS steel head gaskets and full multi-piece sealing kit prevent oil, coolant and vacuum leakage
- Full set of lifter trays, valley plate, manifold gaskets and stem seals covers all overhaul sealing demands
All parts adopt OEM-grade wear-resistant alloy and heat-resistant composite materials, ideal for full engine rebuild of GM pickup trucks and full-size SUVs. Integrated all core repair components save separate parts purchasing time for repair shops and DIY enthusiasts.
Warranty & Customer Support
1-Year limited warranty against manufacturing defects. All engine components are covered under warranty for 12 months after purchase. If any part fails due to defective raw materials or workmanship under normal driving conditions, we provide free replacement of faulty parts.
