Non A-FM Camshaft Lifter Engine Rebuild Kit for Chevy GMC

This non AFM camshaft and lifter rebuild kit deletes the Active Fuel Management system on 2014-2021 Gen V L83 5.3L engines for Chevy GMC to restore full-time V8 power and eliminate AFM-related lifter failures.

Overview

The Non A-FM Camshaft Lifter Engine Rebuild Kit replaces the factory AFM hardware in 2014-2021 Gen V L83 5.3L V8 engines for Chevy GMC. This non AFM kit deactivates cylinder deactivation, providing consistent power delivery and solving lifter collapse issues common to AFM-equipped trucks and SUVs. Engine builders and do-it-yourself mechanics choose this non AFM camshaft and lifter set to convert their L83 engine into a standard V8 without active fuel management.

• Includes a complete set of lifters designed to work without AFM oil manifold interference
• Hardened cam lobes and lifter rollers increase wear resistance under high-load conditions
• Direct replacement for factory AFM cam and lifters with no special tuning requirements beyond AFM disable
• Restores consistent oil pressure by removing AFM valve lifters and associated solenoids
• Engineered to match stock Gen V L83 valve spring rates and pushrod length

Specs At A Glance

Good To Know

Q: Do I need to tune the ECM after installing this non AFM kit? A: Yes, you must either disable AFM in the ECU using tuning software or install an AFM disabler module; the camshaft and lifters will function mechanically but the computer will set codes if AFM is not disabled.

Q: Will this camshaft cause a rough idle or check engine light? A: The non AFM camshaft profile is designed to match stock exhaust and intake parameters, so idle quality remains smooth, and with proper AFM disable tuning, no check engine light will appear.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
