Camshaft & Lifter Kit for 1999-2012 Chevrolet Silverado / GMC Sierra

Camshaft & Lifter Kit is designed for 1999-2012 Chevrolet Silverado / GMC Sierra and supports coordinated valvetrain service after cam-lobe, lifter-roller, or related timing wear has been diagnosed. The service scope centers on the camshaft, lifter style, timing interface, and engine-control configuration defined for this kit.

During operation, the camshaft establishes valve timing and lift while the matched lifters transfer lobe motion through the valvetrain. Inspection commonly follows persistent valvetrain ticking, cylinder-specific misfires, a rough idle, or measured cam and lifter wear. The same inspection should cover the cam lobes, lifter rollers, pushrods, rocker arms, valve springs, oil passages, and timing components because wear or damage there can affect the replacement. Use assembly lubricant, verify valvetrain clearances, align the timing drive, torque the fasteners correctly, and follow the required start-up procedure. Install this Camshaft & Lifter Kit only in the stated component position and configuration.

Features

• Coordinates the camshaft and matched valvetrain components used in the stated repair scope.
• Cam-lobe geometry controls valve timing and lift through the engine's mechanical valvetrain.
• Matched lifter construction follows the specified lobe profile and engine-control configuration.
• Retains the stated timing-drive and cam-phasing interfaces where those components are part of the kit.
• Configured for the Engine, Valve Train, Timing System installation position.
• Uses the listed rpm range configuration: 2200-5400 RPM.
• Supports service after inspection identifies wear at the cam lobe, lifter roller, or related valvetrain interface.
