Delete AFM.
Restore the V8.

A complete mechanical AFM/DOD delete system for 2005–2014 Chevy & GMC 5.3L Gen IV V8s—replacing failure-prone active lifters with a reliable non-AFM valvetrain and renewing critical engine components.

AFM lifters frequently collapse, causing ticks, misfires, and cam damage. A mechanical delete permanently fixes this with a reliable, standard valvetrain.

Teardown exposes the cam, lifters, timing, oil, and cooling systems. Replacing them together saves you from paying double labor later.

A custom ECU tune is strictly required to disable AFM electronically. Always verify your engine RPO and cam bolt style before ordering.

Fitment check Fits compatible 2005–2014 GM 5.3L Gen IV V8s with AFM/DOD. Uses a 1-bolt cam and equal-length head bolts.

Understand the failure. Follow the fix.

See why a proper AFM delete requires more than just a lifter replacement.

01

Ticking is the warning—not the repair.

A collapsed AFM lifter reduces valve lift, triggers misfires, and destroys the camshaft lobe.

Custom tuning is mandatory

The mechanical delete does not switch AFM off in the computer. AFM/DOD must be disabled in the ECU calibration.

Verify the engine—not only the year

Confirm a compatible 5.3L Gen IV application, 1-bolt camshaft, and Gen IV equal-length head bolt configuration.

Remove the AFM hardware. Bring back dependable V8 operation.
