Melling Performance IS-63 - Chrysler Heavy-Duty Intermediate Driveshafts

Description

A new Melling stock-replacement oil pump intermediate shaft is an essential component to complete any quality oil pump replacement or complete engine overhaul. Transferring rotational drive from the camshaft/distributor gear directly to the oil pump, the intermediate shaft operates under continuous torsional loading and cyclic fatigue. Reusing an original, high-mileage shaft introduces severe risks of sudden valvetrain failure, as used shafts often suffer from undetectable metal fatigue, micro-cracking, or torsional twist—even when visually intact. Made in the USA from high-strength stressproof steel and precision-machined to exacting tolerances, Melling intermediate drive shafts ensure correct hex engagement depth, smooth concentric rotation, and worry-free lubrication system reliability.

Features & Technical Highlights:

• Critical Drive Protection: Eliminates catastrophic loss of oil pressure caused by twisted hex ends or torsional failure of an aged, fatigued factory shaft.
• Stressproof Steel Construction: Precision-manufactured from high-grade alloy steel to withstand continuous rotational torque without deflection or galling.
• Direct OEM Replacement: Matches factory overall length, hex profile, and shaft diameter for seamless, bind-free alignment between the distributor/drive gear and oil pump.
• Essential Rebuild Best Practice: Melling strongly recommends replacing the intermediate driveshaft with every new oil pump installation to protect engine bearings and ensure warranty compliance.
• Made in the USA: Built domestically under strict quality control to guarantee dependable, long-term lubrication system performance.
