Product Details

KYB Mount Components focuses on replacement suspension mounting parts that address noise and vibration at the spring seat. This coil spring insulator is engineered for front upper use on a wide range of Chrysler, Dodge, and Plymouth vehicles, including Chrysler LeBaron, Dodge Caravan, and Plymouth Voyager applications. If the original insulator has hardened, cracked, or compressed, the SM5219 can restore proper spring isolation and help reduce unwanted contact noise at the mount.

This part cross-references Chrysler 4014441 and Gabriel 142940 for the same application.

What It Helps Fix

• Squeaks from worn or deteriorated spring seat material
• Rattles caused by loose or compressed suspension insulation
• Vibration noise transmitted through the front upper mount
• Noise from aging coil spring contact points
• Ride harshness related to degraded mount components

Installation Notes and Tips

• Verify year, make, model, and front upper position before ordering.
• Inspect the surrounding mount components and spring seat surfaces for wear or damage.
• Replace the insulator when the original part shows cracking, flattening, or hardening.
• Confirm fitment for vehicles with notes such as the Chrysler New Yorker and Chrysler Imperial exclusions listed for air suspension applications.
