Its 1.988 installed height, 1.466 spring open height, and 1.429 coil bind height provide the dimensional reference needed when matching valvetrain components. The 0.65 inside diameter and 1.299 outside diameter further define the spring for proper fitment in supported engine builds. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., 32-5024, 160-1642SSA) for the same application.\u003c\/p\u003e\u003cp\u003eCompatible with stock-use applications across the Dodge Durango, Ram 2500, Ram 3500, Jeep Grand Cherokee L, Ram 1500, Ram 1500 Classic, Ram 4500, Ram 5500, Chrysler 300, Dodge Challenger, Dodge Charger, Jeep Grand Cherokee, Jeep Wagoneer, Dodge Ram 1500, Dodge Ram 2500, Dodge Ram 3500, and Jeep Commander.

Confirm the engine uses a hydraulic roller camshaft and compare the spring dimensions to the original specification. Use the vehicle fitment list to confirm the correct application for your Chrysler, Dodge, Jeep, or Ram engine build. The VS-1642 part number should be matched carefully during service work to avoid valvetrain mismatch.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eMelling offers valve springs across standard, heavy-duty, and race-ready categories, with multiple wire sizes, materials, and spring pressure ranges available.
