Prothane 7-1155-BL Front Sway Bar Bushing Kit 32mm GM S-Series 4WD 1983-2000

The Prothane 7-1155-BL is a front stabilizer bar bushing kit designed for GM S-Series 4WD vehicles from 1983 to 2000. Engineered to replace worn or soft factory rubber bushings on 32mm sway bars, these polyurethane bushings deliver improved handling, reduced body roll, and greater steering response compared to OEM-spec components.

Prothane's polyurethane compound is significantly firmer than stock rubber, which translates directly into a tighter, more controlled feel through corners and during directional changes. Each bushing features a grooved inner bore that retains Prothane's proprietary super grease, ensuring smooth, quiet operation without the squeaking or binding often associated with aftermarket polyurethane parts.

Key Features:

• Fits 32mm front stabilizer bars on GM S-Series 4WD applications (1983–2000)
• Made from firm, durable Prothane polyurethane — resists oil, heat, and weathering
• Grooved bore design retains included super grease for quiet, long-lasting performance
• Direct replacement for OEM rubber bushings — no modifications required
• Black (BL) color finish
• Significantly reduces sway bar deflection for improved handling and cornering stability

Prothane polyurethane bushings are a proven upgrade for enthusiasts and daily drivers alike who want to maximize the performance of their factory or upgraded sway bar without a full suspension overhaul. The included grease and hardware make installation straightforward.
