Prothane 7-403 Front Sway Bar End Link Bushing Kit

The Prothane 7-403 is a front stabilizer bar end link kit engineered from high-performance polyurethane to replace the worn or degraded factory rubber bushings on C4 Corvettes. Unlike soft OEM rubber that compresses and deforms under load, Prothane's polyurethane formulation holds its shape, keeping the front sway bar firmly connected to the suspension and delivering consistent, predictable handling characteristics.

Worn end link bushings are a common source of clunking noises, increased body roll, and vague steering feel. By upgrading to this polyurethane kit, the front anti-roll bar can transfer force more efficiently between the left and right suspension corners, reducing body lean during cornering and improving overall chassis response.

Key Features:

• Polyurethane construction — significantly firmer and more durable than OEM rubber
• Resists oil, ozone, and UV degradation for long service life
• Grooved bore design retains grease for quiet, rattle-free operation
• Available in red or black to suit your preference
• Direct factory replacement fitment — no modifications required
• Backed by Prothane's lifetime warranty
• Made in the USA

The Prothane 7-403 end link bushing kit is a cost-effective suspension upgrade that restores tight, responsive handling and eliminates the slop and noise associated with deteriorated stock rubber components.
