Prothane 7-1113-BL Front Sway Bar Bushing Kit 28mm GM S-Series 4WD

The Prothane 7-1113-BL is a front stabilizer bar bushing kit designed for GM S-Series 4WD vehicles (1983–2000) with a 28mm sway bar diameter. These polyurethane bushings are a direct upgrade over the factory rubber units, restoring and improving the effectiveness of your OEM stabilizer (anti-roll/sway) bar.

Key Features:

• Manufactured from firm, high-durometer polyurethane for superior performance over stock rubber
• Grooved bore design engineered to retain Prothane's proprietary super grease for quiet, squeak-free operation
• Reduces body roll and improves cornering stability by eliminating bushing flex and deflection
• Resists deterioration from oil, road salt, ozone, and UV exposure — outlasting OEM rubber bushings
• Precision-molded to 28mm inner diameter for a secure, rattle-free fit
• Black polyurethane finish (BL designation)
• Direct bolt-on replacement — no modifications required
• Includes Prothane super grease for proper installation and long-term lubrication

Upgrading to Prothane polyurethane stabilizer bar bushings is one of the most cost-effective handling improvements available for your GM S-Series truck or SUV. By eliminating the compliance and deflection inherent in soft OEM rubber, these bushings deliver a more responsive, controlled ride without sacrificing daily drivability.
