Product Description
Genuine GM 12619823 L83 5.3L Stock Replacement Camshaft
For L83 Engines with VIN Code C – Retains Factory AFM/DOD Operation
Replace a damaged factory L83 camshaft with Genuine GM part number 12619823. This stock replacement camshaft is intended for compatible 5.3L L83 engines identified by the letter C in the eighth position of the VIN. It maintains the original-equipment configuration, including factory Active Fuel Management (AFM), also known as Displacement on Demand (DOD). Designed for the listed Chevrolet Silverado, Suburban and Tahoe and GMC Sierra and Yukon applications, this GM camshaft is a replacement option for repairs that retain the original L83 cylinder-deactivation system.
Key Features & Benefits
- Genuine GM Part Number 12619823: Provides an original-equipment GM camshaft for compatible L83 engine repairs. The exact GM part number offers a clear replacement reference when sourcing a stock camshaft to replace a damaged original component.
- Stock L83 Replacement: Intended for repairs that preserve the factory 5.3L L83 engine configuration. This camshaft is suited to owners and builders seeking an OEM replacement during engine service rather than changing to a performance camshaft profile.
- Retains Factory AFM/DOD: Designed for continued use of the engine's original Active Fuel Management system. Its stock application supports L83 repairs where the factory cylinder-deactivation hardware and operating configuration remain in place.
- VIN Code C Identification: Applicable engines are identified by C as the eighth digit of the VIN. This engine identifier is especially important for 2019-later vehicles, when some models began using the newer L84 engine instead of the L83.
- Chevrolet and GMC Application Coverage: Listed for compatible L83-powered Silverado, Sierra, Suburban, Tahoe, Yukon and Yukon XL models. The detailed applications below include the specified LTD and Limited models, with VIN code C required throughout the fitment list.
Notes
- Not for AFM/DOD conversion builds. This camshaft retains the factory AFM/DOD system.
- Not for L84 engines. For 2019-later models, verify that the eighth digit of the VIN is C before ordering.
