Restore factory ride quality and proper sway bar function with this 1965–1966 Ford Mustang Sway Bar Insulator – 5/8" Rubber.

Specifically designed for early first-generation Ford Mustang models equipped with a 5/8" sway bar, this rubber insulator provides the correct factory-style fit and feel. Over time, original insulators can dry out, crack, and compress — allowing excess sway bar movement that leads to front-end noise and reduced handling stability.

Factory-Correct Performance

Unlike polyurethane upgrades, this high-quality rubber insulator maintains the original ride characteristics your Mustang was built with, offering:

• Proper sway bar cushioning

• Reduced road noise and vibration

• Smooth, compliant ride quality

• Authentic restoration appearance

Features:

• Correct fit for 1965–1966 Mustang models with 5/8" sway bar

• Durable OEM-style rubber construction

• Designed to properly secure the sway bar

• Direct replacement for easy installation

• Ideal for stock restorations and daily drivers

Whether you're completing a concours restoration or simply replacing worn components, this sway bar insulator ensures your Mustang retains its original comfort and performance balance.

Keep your classic riding smooth and true to factory specifications — just the way it left the showroom.
