Description
Product Overview
The EPChunMi AFM DOD lifters are engineered to match the original equipment specifications of fourth‑generation DOD/AFM V8 engines found in a wide range of GM trucks and SUVs from 2005 to 2018. Each package contains eight fully inspected lifters, forged from high‑strength steel and finished with a corrosion‑resistant coating. Weighing 3.16 pounds for the set, the lifters fit inside the engine block and operate with #68 hydraulic oil, ensuring smooth camshaft interaction and optimal valve lift. The part numbers (12569256, 12571595, 12632143, etc.) guarantee compatibility with models such as the Chevrolet Suburban, GMC Sierra, Cadillac Escalade, and Buick LaCrosse.
Usage
These lifters are intended for professional installation or experienced DIY mechanics working on 4.3L, 5.3L, 6.0L, and 6.2L V6/V8 engines. Replace the lifters when you notice symptoms like ticking or clicking noises, reduced acceleration, engine misfires, or a persistent check‑engine light. Proper installation requires draining the oil, removing the valve cover, and ensuring the hydraulic oil is at the correct viscosity before seating the lifters. Once installed, the engine regains its original performance characteristics, providing reliable power for daily driving, towing, and off‑road adventures.
