Prothane 6-1138 Front Sway Bar Bushing Set 33mm 4WD Polyurethane

The Prothane 6-1138 is a front stabilizer bar bushing set designed for 4WD applications with a 33mm sway bar diameter. These polyurethane bushings are a direct replacement for the factory rubber bushings found on 1997–2002 vehicles, delivering improved handling response and long-lasting durability over OEM-spec rubber.

Stock rubber stabilizer bar bushings are known to soften and deteriorate over time, leading to vague steering feel, excessive body roll, and unwanted noise. Prothane's polyurethane formulation maintains its firmness across a wide range of temperatures and operating conditions, restoring — and often exceeding — the original anti-roll performance of your sway bar.

Key Features:

• 33mm bore diameter — precision-fit for factory and performance sway bars
• Grooved inner bore — engineered to retain Prothane Super Grease for smooth, quiet, rattle-free operation
• Polyurethane construction — resists compression set, oils, and weathering that degrade OEM rubber bushings
• 4WD specific fitment — designed for front stabilizer bar applications on 4-wheel drive vehicles (1997–2002)
• Direct OEM replacement — bolt-on installation with no modifications required
• Compatible with larger-diameter aftermarket high-performance sway bars where applicable

Each set includes the bushings and is designed for use with Prothane Super Grease (sold separately) to ensure proper lubrication and long service life. Upgrade your suspension's sway bar bushings with Prothane 6-1138 for tighter handling and reduced body roll.
