Detailed Description

This suspension stabilizer bar bushing kit is designed for front-to-frame mounting on select Ford F-250, Ford F-350, Ford Mustang, Lincoln Town Car, Mercury Capri, Mercury Grand Marquis, Ford LTD Crown Victoria, and Ford LTD applications. The rubber material helps restore stabilizer bar support at the frame mount, which is important for maintaining consistent bar location and suspension response.

This part cross-references MOOG Chassis Products K80095 for the same application.

What It Helps Address

• Clunking or rattling from worn stabilizer bar bushings
• Excessive sway bar movement at the frame mount
• Loose or degraded front suspension feel
• Noise caused by hardened, cracked, or compressed rubber bushings
• Restoring stabilizer bar support on high-mileage Ford, Lincoln, and Mercury vehicles

Installation Notes and Tips

• Verify the stabilizer bar diameter before installation; this part is for a 30 mm bar size.
• Confirm front-to-frame mounting location and vehicle configuration before ordering.
• Inspect the stabilizer bar and mounting surfaces for wear, corrosion, or damage before installing the new bushings.
• Because no grease fitting is included, install as a dry rubber bushing unless the vehicle service procedure specifies otherwise.
