Polybush kits are one of the most effective ways to restore steering feel and suspension control without turning the car into a full strip-down project. Each kit contains the polyurethane bushes needed for a specific location on the car. This page brings together the full Big Healey and Sprite & MG Midget range of Polybush kits listed on A H Spares. If you are not sure whether your bushes are due, start with our practical guide: Do Your Suspension Bushes Need Replacing?

Clear model coverage: Big Healey (100, 100-Six, 3000) and Sprite & MG Midget kits separated for accuracy.
Grouped by area: Anti-roll bar, front suspension, rear suspension, plus gearbox tie bar bushes where applicable.
Decision-ready listings: Polybush kits are presented in tables with direct links to individual product pages.
Useful even in phases: Start with the bushes that affect steering feel and axle location most, then complete the rest when it suits your schedule.

How the Polybush kits are organised

Each model page is split into practical sections so you can replace bushes in a logical order and avoid missing the parts that control steering feel and axle location.

Anti-roll bar bushes: Helps the bar work consistently and improves predictability in corners (if fitted).
Front suspension bushes: Controls geometry and steering feel, especially under braking and turn-in.
Rear suspension bushes: Keeps the axle and springs located properly for a planted rear end.
Gearbox tie bar bushes: Where applicable, reduces unwanted movement and improves drivetrain control.

Why owners choose polyurethane bushes

Rubber bushes made sense when these cars were new. Decades later, many are tired, compressed, or cracked, which lets suspension geometry wander. Polyurethane is often chosen because it holds its shape better over time and keeps suspension movement more consistent.

More consistent geometry: reduces vagueness and repeated alignment drift.
Suited to occasional use: less affected by long lay-ups and low annual mileage.
Stable under load: resists deformation that can contribute to wandering and clunks.

FAQs

What is included in a Polybush kit?

Each kit contains the polyurethane bushes required for one specific location on the car, such as an anti-roll bar, wishbones, rear suspension, or gearbox tie bar. The exact contents are listed on each individual kit page.

How do Touring and Performance kits differ?

Touring kits use a more compliant compound aimed at road comfort and noise control. Performance kits use a firmer compound to reduce compliance and movement. The firmer option can feel more direct, but may transmit more vibration on some cars.

How do I choose the correct anti-roll bar bush kit?

Choose by anti-roll bar diameter, not by model name alone. Measure the outside diameter of your existing bar, or order the kit that matches the bar you are fitting.

Do these kits suit standard and uprated setups?

Most kits suit standard suspension layouts, and many also suit uprated components where the mounting points remain standard. If a kit has a chassis break or specific exclusion, it will be stated clearly on the product page.

Will polyurethane bushes make the car harsh or noisy?

Touring kits are intended to retain compliance suitable for road use. Performance kits are firmer to reduce bush deflection, which can sharpen steering response, improve stability under braking, and keep suspension geometry more consistent. The trade-off is that some cars may transmit more vibration or drivetrain feel, especially on rougher roads.

Do I need special tools to fit Polybush kits?

It depends on the location. Some bushes install with basic hand tools, while others may need a press or a suitable bush tool, plus careful support of suspension or axle components during removal and refitting. Always check the installation notes on the product page and inspect pins, sleeves, and brackets for wear before refitting. If any step is unfamiliar or you are not confident supporting the car safely, a professional mechanic or classic car workshop is the sensible option.
