Austin-Healey Sprite / MG Midget Anti-Roll Bar Polybush Kit 9/16in – Performance

What is this anti-roll bar polybush kit?

This performance-grade polyurethane bush kit is designed for the front anti-roll bar (A.R.B.) fitted to Austin-Healey Sprite and MG Midget models using a 9/16-inch diameter bar. It replaces standard rubber bushes to reduce deflection and improve steering response.

Key benefits

• Reduced anti-roll bar deflection compared with rubber bushes
• More consistent bar location during cornering
• 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 Sprite or Midget?

Yes, if your car is fitted with a 9/16-inch front anti-roll bar. This kit fits Sprite MK1–MK4 and Midget MK1–MK3 models using a true 9/16-inch A.R.B.

• Austin-Healey Sprite MK1, MK2, MK3, MK4
• MG Midget MK1, MK2, MK3

Does not fit:

• Cars without a front anti-roll bar
• Models fitted with alternative bar diameters
• Aftermarket competition bars unless diameter matches exactly

Quick check before ordering: a 9/16-inch anti-roll bar measures approximately 14.3mm.

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: 9/16-inch
• Environmental resistance: Oil, fuel, weather, and road dirt
• Compliance level: Reduced compared with touring-grade bushes

Installation & setup notes

Installation reuses the existing anti-roll bar clamps and brackets and can be carried out with standard hand tools.

• Light lubrication recommended during fitting
• Confirm bar diameter before installation
• Final tightening should be carried out at normal ride height

A firmer transmission of road feel should be expected compared with touring-grade bushes.

Why choose the performance specification?

The performance compound is intended for drivers who prioritise steering accuracy and reduced roll compliance. Compared with touring-grade A.R.B. bushes, it offers lower compliance and more consistent behaviour under load.
