Prothane 4-1101 Front Sway Bar Bushing D50 2WD Polyurethane

Upgrade your front suspension performance with the Prothane 4-1101 polyurethane front sway bar bushings, designed for 2WD applications (1979–1993). Engineered to replace worn, soft OEM rubber bushings, these polyurethane bushings significantly improve the effectiveness of your vehicle's stabilizer (anti-roll/sway) bar, resulting in reduced body roll and sharper, more responsive handling.

Key Features:

• Polyurethane construction — firmer than stock rubber for improved sway bar response and durability
• Grooved bore design — channels are pre-cut to retain Prothane's proprietary super grease, ensuring smooth, quiet operation over the long term
• Direct OEM replacement — designed as a drop-in upgrade for factory sway bar mounts on 2WD vehicles
• D50 application-specific fitment — precision-molded to match the correct bar diameter and mounting geometry
• Also compatible with larger-diameter high-performance aftermarket sway bars — making this an ideal choice for enthusiasts who have already upgraded their anti-roll bar

Prothane polyurethane bushings are manufactured in the USA and are a trusted choice for street performance and light off-road use. By eliminating bushing deflection and flex, the Prothane 4-1101 helps your sway bar work as intended — keeping your vehicle flat in corners and improving overall stability.
