Product Description

Gen IV AFM/DOD Conversion Kit for 6.0L & 6.2L LS Engines

Fits Select 2007-2017 GM 6.0L & 6.2L Applications | LS7 Lifters, Non-AFM Valley Cover, LS9 Head Gaskets & More

Convert a compatible Gen IV 6.0L or 6.2L LS engine from the factory AFM/DOD valvetrain arrangement to a non-AFM configuration with this comprehensive conversion kit. It includes Delphi LS7 hydraulic roller lifters, a non-AFM Gen IV valley cover, GM lifter guide trays, LS9 seven-layer head gaskets, head bolts, and multilayer exhaust manifold or header gaskets. A compatible non-AFM camshaft is required for the conversion; the GM L96 camshaft, part number 12626660, is a stock-sized option suitable for compatible VVT and non-VVT 6.0L and 6.2L applications.

Key Features & Benefits

• Complete Non-AFM Valvetrain Conversion Package: Combines the primary lifter, valley cover, sealing, fastener, and exhaust gasket components needed for a compatible Gen IV 6.0L or 6.2L AFM/DOD conversion.
• Delphi LS7 Hydraulic Roller Lifters: Includes a complete set of 16 Delphi LS7-style hydraulic roller lifters for a full V8 valvetrain service during the non-AFM conversion process.
• Non-AFM Gen IV Valley Cover Option: Includes a non-AFM Gen IV LS valley cover with gasket and mounting bolts. Choose between a reproduction L92-style cover or an OEM GM cover option.
• Complete Gasket & Fastener Support: Includes LS9 seven-layer head gaskets for 6.0L and 6.2L applications, a 2004+ LS head bolt kit with optional ARP upgrade, and two multilayer exhaust manifold or header gaskets.
• Camshaft Flexibility for VVT or Non-VVT Builds: GM L96 camshaft 12626660 is a stock-sized non-AFM option for compatible VVT and non-VVT 6.0L and 6.2L engines. Other compatible camshaft selections may require additional supporting parts and calibration changes.

Specs

• Product Type: Gen IV LS AFM/DOD conversion kit
• Engine Compatibility: Select 6.0L and 6.2L Gen IV LS engines only
• Lifters: Delphi LS7 hydraulic roller lifters, set of 16
• Lifter Trays: GM 12595365, set of 4
• Valley Cover: Non-AFM Gen IV LS cover with gasket and mounting bolts
• Head Gaskets: LS9 seven-layer gaskets for 6.0L and 6.2L engines

Notes

• Camshaft Requirement: The original AFM/DOD camshaft should be replaced with a compatible non-AFM camshaft during this conversion to help avoid potential misfire concerns.
• PCM Calibration Required: The AFM/DOD function must be turned off in the vehicle PCM after installation. A stock-sized camshaft such as the L96 12626660 may not require additional calibration changes beyond the AFM/DOD PCM adjustment.
• Engine Restriction: This kit is intended only for compatible 6.0L and 6.2L applications listed below. Verify engine displacement, model year, engine code, and existing valvetrain configuration before purchase.
• VVT Compatibility: The GM L96 12626660 camshaft is suitable for compatible VVT and non-VVT 6.0L and 6.2L engine applications. Confirm all timing components and camshaft requirements before installation.
• Installation Recommendation: Professional installation or advanced LS engine-building experience is recommended. Inspect pushrod length, valve spring clearance, lifter preload, and complete valvetrain geometry during assembly.
