Prothane 7-1138 Front Sway Bar Bushing Set 33mm GM S-Series 2WD 1982-2000

Upgrade your GM S-Series truck or SUV's handling with the Prothane 7-1138 front sway bar bushing set. Engineered as a direct replacement for worn or soft factory rubber bushings, these 33mm polyurethane bushings deliver a firmer, more controlled connection between the stabilizer bar and chassis, reducing body roll and improving cornering response.

Prothane's polyurethane compound outperforms OEM rubber by resisting compression, oil, and road grime that cause premature wear and bushing deterioration. The result is a more responsive front suspension that maintains its performance characteristics over the long haul.

Key Features:

• 33mm bore sized for factory and compatible aftermarket sway bars
• Grooved bore design retains Prothane Super Grease for smooth, squeak-free operation
• Polyurethane construction resists oil, ozone, and weathering
• Firmer than OEM rubber bushings for improved handling and reduced body roll
• Direct bolt-on fitment — no modifications required
• Available in Prothane's signature purple polyurethane
• Includes Prothane Super Grease for installation

Designed specifically for 1982–2000 GM S-Series 2WD applications, the Prothane 7-1138 is a straightforward suspension upgrade that improves both daily driving comfort and performance handling. Compatible with high-performance larger-diameter sway bar applications as noted by the manufacturer.
