Prothane 18-1108 Polyurethane Sway Bar Bushing - 24mm 4WD

The Prothane 18-1108 is a polyurethane stabilizer bar bushing designed as a direct replacement for worn or soft OEM rubber bushings on 4WD applications. Engineered for 24mm diameter sway bars, this bushing delivers a measurable improvement in handling and body roll control compared to stock rubber components.

Prothane's polyurethane compound is significantly firmer than factory rubber, reducing the flex and deflection that allows excessive body roll during cornering. The bore features precision-machined grooves designed to retain Prothane's proprietary super grease, ensuring smooth, quiet operation throughout the life of the bushing.

Key Features:

• 24mm inner diameter for precise sway bar fitment
• High-durometer polyurethane construction for improved rigidity over OEM rubber
• Grooved bore retains Prothane super grease for quiet, squeak-free operation
• Designed for 4WD vehicles, 1989–1995 fitment
• Direct OEM replacement — no modifications required
• Resistant to oils, solvents, and environmental degradation
• Compatible with larger diameter high-performance aftermarket sway bars (see fitment notes)

Upgrading to the Prothane 18-1108 polyurethane sway bar bushing is a straightforward suspension improvement that tightens steering response and reduces unwanted chassis flex, making it an ideal choice for both daily drivers and off-road enthusiasts seeking better control and durability.
