Austin Healey Anti-Roll Bar Polybush Kit 9/16in – Touring (BN1–BN2)

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 early Austin Healey models using a 9/16-inch diameter bar. It replaces standard rubber bushes to improve durability while retaining compliant, period-appropriate suspension behaviour.

Key benefits

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

Will this fit my Austin Healey?

Yes, if you have a BN1 or BN2 fitted with a 9/16-inch front anti-roll bar. This kit is intended specifically for early Big Healey models using the smaller-diameter A.R.B.

Does not fit:

• BN4, BN6, BN7, BT7, BJ7, or BJ8 models
• Cars fitted with 5/8-inch, 3/4-inch, or 7/8-inch anti-roll bars

• Touring-grade polyurethane anti-roll bar bushes
• Correct quantity to service one complete front A.R.B.

Technical details

Installation & setup notes
