Spax Telescopic Rear Suspension Kit – Late Sprite & Midget

Overview

This Spax telescopic rear suspension kit is designed for later Austin Healey Sprite MK3–MK4 and MG Midget MK2–MK3 models. It replaces the original lever arm dampers with gas-pressurised telescopic units, offering improved control and on-car adjustability.

The system allows both bump and rebound damping to be adjusted without dismantling, making it easier to fine-tune the suspension setup for different driving conditions.

Key Benefits

• On-car adjustable damping settings
• Control over bump and rebound characteristics
• Gas-pressurised dampers for consistent performance
• Conversion from lever arm to telescopic system
• Supplied with installation hardware
• Dyno tested dampers

Fitment

• Austin Healey Sprite MK3
• Austin Healey Sprite MK4
• MG Midget MK2
• MG Midget MK3

Suitable for vehicles originally equipped with rear lever arm dampers.

Not intended for vehicles already converted to telescopic systems or non-standard suspension layouts.

What’s Included

• Pair of Spax adjustable telescopic dampers
• Mounting brackets and fixings
• Hardware required for conversion

Technical Details

• Krypton gas-filled dampers
• Adjustable bump and rebound
• On-car adjustability
• Dyno tested
• Designed for compatibility with standard rear leaf spring suspension

Installation

Installation involves removing the original rear lever arm dampers and fitting the supplied brackets and telescopic shock absorbers in their place. The kit is designed to work with the standard rear leaf spring and axle arrangement.

• The rear axle must be safely supported independently of the chassis before removal of the original dampers
• Original lever arm dampers and associated fixings are removed as part of the conversion
• Mounting brackets must be correctly aligned before final tightening
• All fixings should be checked and tightened once the vehicle is back at normal ride height

This is a suitable installation for an enthusiast with prior experience working on suspension systems and safe vehicle support. A good understanding of working underneath the vehicle and handling suspension components is required.

Professional installation may be required where:

• Mounting points show signs of wear, corrosion, or previous repair
• Bracket alignment cannot be achieved cleanly during fitting
• The vehicle has non-standard suspension components or modifications
• There is uncertainty around correct installation or setup

After installation, damping settings should be adjusted gradually to suit driving conditions. Incorrect adjustment may affect ride quality and handling.

Why Choose This Part

This kit provides a more adaptable suspension setup compared to original lever arm dampers. Adjustment can be made quickly to suit road conditions, load, or driving style, offering a practical solution for maintaining consistent rear suspension performance.
