Additional information:
Description:

What is this anti-roll bar polybush kit?

This is a touring-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 provide controlled compliance while improving durability and consistency.

Key benefits

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

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 true 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: a 3/4-inch anti-roll bar measures approximately 19.0mm across the bar.

What’s included in the kit?

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

Technical details

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

Installation & setup notes

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

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

Compared with performance-grade bushes, this touring compound allows more controlled movement of the anti-roll bar.

Why choose the touring specification?

The touring compound is designed for owners who value comfort, reduced noise transmission, and relaxed road behaviour. Compared with performance-grade A.R.B. bushes, it offers greater compliance while still improving durability and consistency over rubber.

FAQs

Is this softer than the performance anti-roll bar bushes?

Yes. The touring compound has higher compliance, allowing more movement than the performance-grade version.

Will this improve ride comfort?

Compared with performance-grade bushes, the touring compound transmits less road feel and noise.

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

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

Are these suitable for fast road driving?

Yes, though drivers prioritising maximum steering precision may prefer the performance specification.
