Prothane 8-1144 Front Sway Bar Bushing Kit 28mm Polyurethane

The Prothane 8-1144 is a front stabilizer bar bushing kit engineered in polyurethane to replace the factory rubber sway bar bushings. Designed specifically for the front suspension, this kit fits a 28mm sway bar and delivers a noticeable improvement in handling precision and body roll control over stock components.

Over time, OEM rubber sway bar bushings stretch, compress, and lose their grip on the bar — allowing the stabilizer bar to shift during cornering. Prothane's firm polyurethane construction holds the sway bar securely in place, reducing body roll, improving traction, and sharpening steering response. The upgrade delivers handling characteristics comparable to installing a larger-diameter sway bar, but at a fraction of the cost.

Key Features:

• Engineered-fit polyurethane bushings sized for a 28mm front sway bar
• Split bushing design for simplified installation — no need to fully remove the sway bar
• Grooved bore retains supplied lubricant for quiet, squeak-free operation
• Available in red or black — both are the same durometer (hardness); black contains a small amount of graphite to further resist squeaking
• Far more durable than OEM rubber — resists sagging, cracking, and deterioration
• Compatible with both OE and larger-diameter aftermarket sway bars
• Made in the USA
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship

Installation is straightforward thanks to the split bushing design. Be sure to apply the included Prothane super grease to the bore at installation to ensure long-lasting, noise-free performance.
