MOOG Suspension Stabilizer Bar Bushing Kit K3171 for Jeep Wrangler — Thermoplastic, Quiet Operation

MOOG K3171 is a thermoplastic sway bar bushing kit engineered to restore precise stabilizer-bar operation on compatible Jeep and select truck models.

When a stabilizer bar bushing wears, steering feel and cornering stability can degrade. MOOG’s K3171 kit uses engineered thermoplastic compounds and performance-driven geometry to resist cracking, swelling or premature wear from road grime, salts and oils. The result is quieter operation, predictable handling and a longer service life compared with many original-equipment rubber bushings.

How will these bushings affect steering and handling?

Replacing worn bushings with MOOG K3171 restores correct sway bar positioning and reduces unwanted movement that causes imbalance or noise. Drivers typically notice crisper turn-in and a reduction in clunking or squeaks as the stabilizer bar resumes its designed load transfer between wheels.

• Reduces lateral play for more consistent cornering response
• Engineered for quiet operation to eliminate squeaks and clunks
• Resists contamination and degradation for steady performance

Are these bushings a direct fit for my Jeep or truck?

MOOG K3171 was manufactured with specific vehicle coverage in mind: multiple Jeep models from the mid-1980s through the late 1990s, plus select Dodge and truck platforms. Always confirm fit by entering your vehicle’s year, make, model, engine and trim into the parts fit tool before ordering.

• Covers various Jeep Wagoneer, Cherokee, Comanche, Wrangler and Grand Cherokee years
• Includes fitment notes for certain Dodge Dakota and Grand Wagoneer applications
• Use the vehicle fit checker and review any special fitment notes before purchase

What materials and testing back this kit’s durability?

MOOG selects thermoplastic materials that withstand flexing, heat cycles and exposure to oils and road chemicals better than conventional rubber. The K3171 bushings undergo extensive engineering validation and durability testing to ensure they resist splitting, discoloration and deformation with age.

• High-quality thermoplastic construction for longer service life
• Tested through MOOG’s design and development rigors for consistency
• Optimized profile reduces wear and channels contaminants away

How difficult is installation for a DIY mechanic?

MOOG designs its suspension parts for straightforward installation with common tools; many technicians and experienced DIYers can change stabilizer bar bushings in a couple of hours depending on corrosion and access. Because these bushings are engineered to seat cleanly and work quietly, reassembly typically returns the stabilizer bar to near-new operation without additional modification.

• Simple clamp-style or split-bushing mounting suits standard tools
• Inspect brackets and fasteners for rust or wear during replacement
• Torque hardware to factory specifications for best results

Who is this product for? MOOG K3171 is aimed at Jeep owners and light-truck drivers restoring steering precision and reducing suspension noise on older models covered by the fit list. It’s a practical choice for mechanics and DIYers who want a durable, tested replacement that matches or improves on original performance without expensive upgrades. Before ordering, confirm vehicle compatibility using the provided fitment tool and review any model-specific notes to ensure correct application.
