Austin-Healey Sprite / MG Midget Anti-Roll Bar Polybush Kit 5/8in – Touring

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 Sprite and MG Midget models using a 5/8-inch diameter bar. It replaces standard rubber bushes to improve durability while retaining compliant, road-friendly suspension behaviour.

Key benefits

• Improved service life compared with rubber bushes
• Controlled compliance for comfortable everyday driving
• 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 Sprite or Midget?

• 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 9/16-inch or other alternative bar diameters
• Aftermarket blade-type or competition bars unless diameter matches exactly
