Prothane 4-1141 Front Sway Bar Bushing Kit 30mm Polyurethane

The Prothane 4-1141 is a front stabilizer bar bushing kit designed for 30mm sway bars. Engineered from premium-grade polyurethane, these bushings deliver a significant handling upgrade over worn or soft factory rubber components, reducing body roll and improving cornering stability.

Polyurethane holds its shape and grip far better than rubber, resisting breakdown from road grime, weather exposure, and oils. The result is a firmer, more precise connection between the sway bar and chassis — delivering handling response comparable to installing a larger-diameter sway bar, without the expense.

Key Features:

• Fits 30mm (1.18") front stabilizer/sway bars
• Premium polyurethane construction — significantly more durable than OEM rubber
• Grooved bore design retains Prothane Super Grease for quiet, squeak-free operation
• Resists degradation from oil, road chemicals, and UV exposure
• Reduces body roll and improves cornering traction and steering response
• Available in red or black
• Includes Prothane Super Grease for proper installation lubrication
• Backed by Prothane's lifetime warranty

Installation is straightforward — simply apply the included Super Grease to the grooved bore before fitting to ensure long-term, noise-free performance. A drop-in upgrade over stock rubber bushings that delivers lasting improvement in suspension feel and control.
