MOOG Suspension Stabilizer Bar Bushing Kit K3171 for Jeep Wrangler — Thermoplastic, Noise‑Reducing

MOOG K3171 is a thermoplastic sway bar bushing kit engineered to restore stabilizer-bar control and reduce noise on compatible Jeep models.

If your Jeep’s steering feels loose or you hear clunks over bumps, worn sway bar bushings can be the culprit. The MOOG K3171 kit uses durable thermoplastic construction and precision molding to resist cracking, swelling and premature wear. MOOG applies thorough engineering and testing to deliver bushings that fit accurately and perform consistently, helping maintain predictable handling and quieter operation.

How will these bushings change my Jeep’s ride and handling?

Replacing old, degraded sway bar bushings with the K3171 kit restores the stabilizer bar’s ability to control body roll and keep steering response crisp. The thermoplastic material reduces deflection compared with aged rubber, which improves lateral stability during cornering and reduces clunks over uneven pavement.

• Reintroduced firm connection between sway bar and chassis for better roll control
• Lower transmission of road shock and vibration into the cabin
• Quieter operation due to tighter tolerances and material damping

Will these bushings fit my Jeep or other vehicles?

The K3171 kit was designed for a broad range of Jeep and some Dodge models—verify fitment prior to purchase. Use your vehicle’s year, make, model, engine and trim in the fitment checker; any supplemental notes shown should be reviewed for special applications.

• Common fitments include older Jeep Wrangler, Cherokee, Wagoneer, Comanche and Grand Cherokee model years listed in the product notes
• Also covers select Dodge Dakota and light-truck platforms in specified years
• Confirm specifics through the vendor’s fitment tool to ensure proper application

What are the material and durability advantages of MOOG K3171 bushings?

MOOG chose high-grade thermoplastic over conventional rubber to resist the common failure modes of split, harden or collapse. The compound resists oils, road salts and grime, which helps the bushings retain shape and function longer under varied environmental conditions.

• Thermoplastic resists cracking and discoloration better than older elastomers
• Precision molding reduces movement that leads to accelerated wear
• Engineered for quiet performance and lower maintenance intervals

How difficult is installation and what should I expect?

MOOG designs these bushings for straightforward replacement with basic tools; many owners complete the swap in a short shop session. Because the kit is engineered to OEM-like dimensions, installation tends to be easier than with poorly fitting aftermarket pieces, but standard safety practices and torque specs should be followed.

• Typical installation requires jack stands, sockets and wrenches
• No special presses usually needed—bushings slip into the stabilizer mounts
• Verify hardware condition and replace any corroded fasteners during the job

Who is this for: The MOOG K3171 Suspension Stabilizer Bar Bushing Kit is aimed at owners of compatible older Jeep and light-truck models who want to correct loose steering, eliminate sway-bar noise, and extend service life with a durable thermoplastic replacement. It’s a practical upgrade for DIY mechanics and professional technicians seeking reliable fitment, improved handling, and a longer-lasting bushing than many stock rubber replacements.
