Additional information:
Description:

What is this rear shackle end polybush kit?

This performance-grade polyurethane bush kit is designed for the rear suspension shackle ends fitted to Austin-Healey Sprite and MG Midget models using the later rear leaf spring arrangement. It provides a firmer polyurethane alternative to the standard OE-style bush assemblies used at the rear spring shackle points.

The performance compound is intended for owners who want reduced compliance and more controlled rear suspension behaviour during fast road driving.

Key benefits

  • Reduced compliance compared with OE-style bush assemblies
  • More consistent rear spring location under load
  • Resistant to oil, fuel, and general road contamination
  • Maintains shape under repeated suspension movement
  • Suited to fast road driving where control is prioritised

Will this fit my Sprite or Midget?

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

Fits:

  • Sprite MK3 to MK4
  • Midget MK2 to MK3

Does not fit:

  • Sprite MK1 to MK2 (1/4 elliptic rear suspension)
  • Midget MK1 (earlier rear suspension layout)
  • Cars with non-standard or modified rear suspension arrangements

What’s included in the kit?

  • Performance-grade polyurethane bushes for rear spring shackle ends
  • Correct quantities to service one complete rear axle shackle set

Technical details

  • Material: Polyurethane (performance compound)
  • Colour: Red
  • Application: Rear suspension shackle ends
  • Resistance: Oil, fuel, and road contamination
  • Compliance level: Reduced compared with touring specification

Installation & setup notes

Installation typically involves supporting the rear axle, removing the shackle pins, and pressing out the existing bush assemblies.

  • Press or suitable bush tools required
  • Inspect shackle pins and mounting holes for wear before refitting
  • Light lubrication assists during assembly
  • Final tightening should be carried out at normal ride height

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 owners who want a polyurethane alternative with reduced compliance for more consistent rear suspension control during enthusiastic road use.

FAQs

Is this stiffer than the touring version?

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

Does this kit cover both sides of the car?

Yes. The kit includes the correct quantities to service both rear shackle ends.

Will this fit early quarter elliptic Sprite models?

No. Sprite MK1 to MK2 use a different 1/4 elliptic rear suspension layout and require different bushes.

Is this suitable for road use?

Yes. It is intended for fast road driving, though increased firmness compared with touring bushes may be noticeable.
