Additional information:
Description:

What is this rear spring pad polybush kit?

This performance-grade polyurethane bush kit is designed for the rear spring pads fitted between the rear leaf springs and axle on later Austin-Healey Sprite and MG Midget models. It provides a polyurethane alternative to the standard OE-style spring pad assemblies using a firmer compound to reduce unwanted movement at the axle-to-spring interface.

The performance compound is intended for owners who want reduced compliance and more consistent axle location during fast road driving.

Key benefits

  • Reduced compliance compared with OE-style spring pad assemblies
  • Helps maintain more consistent axle-to-spring alignment under load
  • Resistant to oil, fuel, and road contamination
  • Maintains shape under repeated compression
  • Suited to fast road use where control is prioritised

Will this fit my Sprite or Midget?

Yes, if your car uses the later rear leaf spring arrangement.

Fits:

  • Sprite MK3 to MK4
  • Midget MK2 to MK3

Does not fit:

  • Sprite MK1 to MK2 (quarter elliptic rear suspension)
  • Midget MK1 (earlier rear suspension layout)

What’s included in the kit?

  • Performance-grade polyurethane rear spring pads
  • Correct quantity to service one rear axle

Technical details

  • Material: Polyurethane (performance compound)
  • Colour: Red
  • Application: Rear spring to axle interface
  • Resistance: Oil, fuel, and road contamination
  • Compliance level: Reduced compared with touring specification

Installation & setup notes

Installation involves separating the rear axle from the leaf springs.

  • Axle support required during fitting
  • Inspect spring centre bolts and axle locating features
  • Ensure pads seat correctly before final tightening

Limitation: The firmer compound may transmit more road feel than the touring specification, particularly on uneven road surfaces.

Why choose this part?

This performance kit suits cars driven enthusiastically on the road where reduced compliance at the axle-to-spring interface is preferred for more consistent rear suspension behaviour.

FAQs

What does a rear spring pad do?

It sits between the rear axle and leaf spring, helping locate the axle and absorb vibration.

Is this stiffer than the touring kit?

Yes. The performance compound has reduced compliance compared with the touring specification.

Does this kit service both sides?

Yes. The kit includes the correct quantity to service both sides of the rear axle.
