The Prothane front sway bar bushing for 1983–2000 GM S‑Series 4WD, sized 25mm in black, replaces the factory mount to secure the front stabilizer bar and reduce unwanted movement. It serves as a direct replacement for the S‑Series front sway bar, restoring proper alignment and helping to eliminate clunking or looseness from worn bushings for improved steering feel.
