Detailed Description

This Dorman stabilizer bar bushing kit, part number 540-590, is designed for direct replacement service on select Dodge and Jeep suspension systems. The rubber and elastomer material helps restore sway bar support at the front-to-frame location, reducing looseness at the stabilizer bar interface and helping maintain consistent suspension control. It is a practical OE-style solution for Ram 1500, Ram 2500, Ram 3500, Wrangler, Dakota, Durango, and Ramcharger applications that use a 30 mm bushing size and do not require a bracket.

This part cross-references MOOG Chassis Products (e.g., K7352) for the same application.

What It Helps Address

• Front stabilizer bar movement caused by worn bushings
• Clunking or rattling from the sway bar area
• Excess play at the front-to-frame mounting point
• Reduced suspension stability from deteriorated rubber bushings
• Service needs on Dodge Ram 1500, Ram 2500, Ram 3500, and Jeep Wrangler front sway bar mounts

Installation Notes and Tips

Verify the vehicle’s front-to-frame stabilizer bar setup before ordering. This Dorman 540-590 kit is specified without a bracket and without a grease fitting, so it should be matched to the original mounting style on the vehicle. Confirm the 30 mm inside diameter and the listed dimensions against the existing bushing before installation.
