Detailed Description

Melling MC1259 is part of the Stock line of OE replacement camshafts, developed for vehicles that need a direct stock-style cam profile rather than an upgraded performance grind. The camshaft uses a hydraulic roller design and is listed with intake lift of 0.384 and exhaust lift of 0.402, along with timing figures that help match the engine’s original operating requirements. This part number, MC1259, is used across Ford Ranger, Ford Explorer, Ford Aerostar, Mazda Navajo, and Mazda B4000 applications listed with stock or OE stock replacement grind notes.

This part cross-references Monroe Shocks & Struts (e.g., CAM422, CS-1510) for the same application.

What It Helps Address

• Worn camshaft lobes that affect valve motion
• Loss of stock engine timing characteristics
• Rough idle caused by camshaft wear
• Reduced torque delivery from an aging valvetrain component
• Replacement needs for stock-style engine rebuilds

Installation Notes and Tips

Verify engine code, emissions notes, and model-year coverage before ordering, especially for California emissions exclusions. Confirm hydraulic roller valvetrain requirements and compare the cam timing specifications to the original part before installation. The MC1259 is listed for multiple Ford and Mazda truck and SUV applications, so fitment should be matched carefully to the exact engine configuration.

Quality Assurance

Melling states that its stock replacement camshafts are developed, engineered, tested, and manufactured to high standards using quality materials. The MC1259 is made in the USA and built as an OE replacement camshaft for stock-style service.
