Description
Genuine Camshaft Phaser for the 2014–2018 Chevrolet Silverado with the 4.3L EcoTec3 V6
This is a new, genuine GM camshaft phaser with OEM part number 12630091, engineered for the 4.3L EcoTec3 V6 engine in the 2014–2018 Chevrolet Silverado. Worn cams and failing phasers cause ticking, rough running and cam-timing codes. Genuine parts keep the factory valve timing. Mason’s Auto Store sells it 36% below the manufacturer’s suggested retail price and ships it across the USA from our Battle Creek, Michigan warehouse.
Catalog fitment notes: Express, Savana. Sierra, Silverado. Works with the VVT solenoid to set camshaft timing.
