Austin Healey Anti-Roll Bar Polybush Kit 3/4in – Performance (BN4–BJ8)
Additional information:
Description:

What is this anti-roll bar polybush kit?

This is a performance-grade polyurethane bush kit for the front anti-roll bar (A.R.B.) fitted to Austin Healey models using a 3/4-inch diameter bar. It replaces standard rubber bushes to reduce bar movement and improve steering response under load.

Key benefits

  • Reduced lateral deflection compared with rubber bushes
  • More consistent anti-roll bar location under cornering load
  • Improved steering response and front-end control
  • Resistant to oil, fuel, moisture, and road contamination
  • Maintains shape under repeated suspension movement

Will this fit my Austin Healey?

Yes, if you have a BN4 to BJ8 fitted with a 3/4-inch front anti-roll bar. This kit suits Big Healey models from BN4 through BJ8 using a 3/4-inch A.R.B.

  • BN4
  • BN6
  • BN7
  • BT7
  • BJ7
  • BJ8

Does not fit:

  • BN1 and BN2 models
  • Cars fitted with 5/8-inch, 7/8-inch, or 9/16-inch anti-roll bars
  • Blade-type or adjustable competition bars unless the bush size matches a true 3/4-inch diameter

Quick check before ordering: measure the bar diameter with calipers or an open-ended spanner as a reference. A 3/4-inch bar measures approximately 19.0mm.

What’s included in the kit?

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

Technical details

  • Material: Polyurethane (performance compound)
  • Colour: Red
  • Anti-roll bar diameter: 3/4-inch
  • Environmental resistance: Oil, fuel, weather, and road dirt
  • Compliance level: Reduced compared with touring-grade bushes

Installation & setup notes

Installation uses the existing A.R.B. clamps and brackets and can be carried out with standard hand tools.

  • Light lubrication recommended during fitting to prevent squeak
  • Confirm anti-roll bar diameter before installation
  • Final tightening should be carried out at normal ride height

Compared with rubber or touring-grade bushes, a firmer transmission of road feel should be expected.

Why choose the performance specification?

The performance compound is intended for drivers who prioritise steering accuracy and reduced body roll over maximum ride compliance. Compared with touring-grade A.R.B. bushes, it offers lower deflection and more consistent behaviour during fast road driving or towing.

FAQs

Is this stiffer than the touring anti-roll bar bushes?

Yes. The performance compound has reduced compliance, resulting in sharper response and increased roll control.

Will this affect ride comfort?

Some increase in transmitted road feel is normal compared with rubber or touring-grade anti-roll bar bushes.

Do polyurethane A.R.B. bushes require maintenance?

No regular maintenance is required once fitted correctly, though lubrication during installation helps prevent noise.

Is this suitable for cars used for towing?

Yes. The reduced deflection of the performance compound makes it suitable for towing applications.
