Description
Eliminate troublesome Active Fuel Management (AFM/DOD) hardware and restore complete valvetrain reliability to your GM Gen V 6.2L L86 engine. Engineered specifically for 2014–2018 Chevrolet Silverado 1500, Suburban, Tahoe, and GMC Sierra 1500 / Yukon models equipped with the EcoTec3 6.2L V8, this all-inclusive delete kit delivers all the physical components required to permanently remove collapsible AFM lifters. By pairing durable Delphi LS7-style non-AFM roller lifters, dedicated valley block-off tower plugs, OEM-grade gaskets, and your choice of non-AFM camshaft, this kit provides a complete mechanical solution to recurring top-end valvetrain failure.
NOW AVAILABLE: We now offer an optional DiabloSport handheld tuner with AFM enable/disable capability alongside all the performance programmer functions of the DiabloSport Predator platform.

Mandatory Requirements & Important Technical Notes:
- Mandatory Camshaft Swap: A non-AFM camshaft replacement is strictly required when deleting AFM on Gen V engines. Retaining factory AFM camshaft lobes with standard non-AFM lifters will lead to improper valve seating and rapid valvetrain failure.
- Oil Gallery Tower Plugs: Includes (8) precision-fit Texas Speed block-off plugs to seal oil delivery to the deactivated lifter galleys beneath the valley cover.
- Proven Delphi Valvetrain: Upgrades all 16 lifter locations to heavy-duty Delphi LS7-style non-AFM hydraulic roller lifters held in place with 4 new Gen V non-AFM guide trays.
- Camshaft Bolt Torque Spec: Due to parts availability and application variations, a replacement cam phaser bolt is not included. GM allows reuse of the factory camshaft phaser bolt one time: torque to 48 ft-lbs plus an additional 50 degrees.
- ECM Recalibration Required: Eliminating physical AFM components requires disabling AFM logic within the engine computer to prevent diagnostic trouble codes (DTCs) and instrument cluster warnings. Select the optional DiabloSport handheld programmer from the dropdown menu, or calibrate using an HP Tuners interface.
