• Standard replacement grade for OE-style engine operation
• Computer controlled compatible for supported applications
• Made in the USA with Melling quality standards
• Part number MC1383 for ordering and verification

Detailed Description

Part number MC1383 is a Melling stock replacement camshaft developed for engines that need an OE-style grind rather than an aftermarket performance profile. The cam uses a hydraulic roller lifter type, 1.7 rocker arm ratio, 114-degree lobe separation, 192 degrees of intake duration at .050 inch lift, and 190 degrees of exhaust duration at .050 inch lift. Intake and exhaust valve lift are 0.4563 and 0.4655, respectively. These specifications support factory-style drivability and the engine characteristics expected in Chevrolet Silverado 1500, GMC Sierra 1500, and related GM truck and SUV platforms.

Melling positions the Stock line as an OE replacement camshaft range for light-, medium-, and heavy-duty applications. MC1383 is intended for buyers restoring original engine behavior or replacing a worn camshaft with a stock-profile component. This part cross-references Monroe Shocks & Struts (e.g., 8-12560-967-0, 12560967) for the same application.

What It Is Used For

• Restoring stock camshaft timing and valve action
• Replacing a worn camshaft in GM truck and SUV engines
• Addressing rough idle caused by cam lobe wear
• Recovering lost torque and drivability from a tired valvetrain
• Returning engine operation to an OE-style profile

Installation Notes and Tips

Verify engine application, camshaft profile, and computer-controlled compatibility before installation. Match the camshaft to the correct hydraulic roller valvetrain setup and confirm rocker arm ratio and lift specifications during engine assembly. Because this is a stock replacement camshaft, it should be installed with attention to timing components, lifter condition, and proper break-in procedures for the engine build.

Quality Assurance

Melling manufactures this camshaft in the USA and develops, tests, and produces its stock replacement line to meet OE replacement standards using quality materials and controlled engineering practices.
