Austin Healey Anti-Roll Bar Polybush Kit 7/8in – Touring (BN4–BJ8)

What is this anti-roll bar polybush kit?

This touring-grade polyurethane bush kit is designed for the front anti-roll bar (A.R.B.) fitted to Austin Healey models using a 7/8-inch diameter bar. It replaces standard rubber bushes to improve durability while maintaining compliant, road-friendly suspension behaviour.

Key benefits

• Improved service life compared with rubber bushes
• Controlled compliance for relaxed road manners
• Reduced sensitivity to oil, fuel, and moisture
• Maintains shape without perishing or cracking
• Lower transmission of noise and vibration than performance-grade bushes
