FAQ

Which leaf spring is correct for my Austin Healey model?

To choose the right spring, check your chassis number, model year and whether yours is early or late BJ8 (for example). The site lists springs by model: e.g. SUR120 for BN1-BN2, SUR121 for BN4-BN6 & early BJ8, SUR122 for late BJ8 (from chassis 26705 onwards). If in doubt, contact us with your vehicle details and we’ll help you select the correct part.

What is the difference between standard, uprated and race / competition springs?

Standard springs are made for normal road use, balancing comfort and correct ride-height. Uprated springs (8-leaf etc) are stiffer, for fast tour-ing or light rally work, giving improved cornering and less bottoming. Race specification springs are for full competition use — they are stiffer still, endure more load, but may compromise comfort and road ride quality.

Will fitting a stiffer or race spring affect ride height?

Yes — stiffer springs often sit higher under load, and may raise the rear end slightly, especially under weight. On competition springs you may need to adjust shocks / bump stops or other geometry to compensate. Always compare measurements before and after fitting.

How long will these springs last and what materials are used?

These springs are made from high-quality spring steel and treated for durability. Under normal road conditions, a set should last many years. Usage in competitions or harsh conditions reduces lifespan — regular inspection for cracks, wear or sagging is recommended.

Can I use the same springs for towing or carrying heavy loads?

Not always: carrying extra load or towing may overload standard springs. For heavier loads you should use uprated or race specification springs, which are designed to deal with higher stresses. Be sure to check your load limits and consider adjusting other suspension components.

Do I need to replace matching leaf springs on both sides?

Yes — it's strongly recommended to replace both rear springs together. Mismatched springs (one new, one old) can lead to uneven ride height, unpredictable handling, and uneven wear on other suspension components.

Is any special installation / alignment required?

You’ll need to ensure that the spring is installed with correct centres, shackles, and shackles’ bushings in good condition. After fitting, check ride height and wheel alignment, and make adjustments as needed. It may help to re-torque the bolts after a short test drive.

What is the shipping & lead time for these springs?

Lead times vary depending on stock and specification (standard vs race). Usually in stock items are dispatched promptly. International orders may incur additional shipping times. Contact our sales team for precise estimates.

Do rear springs affect front suspension behaviour?

Yes in many ways. The rear spring stiffness and ride height affect weight distribution, roll, and pitch. If you change rear springs (especially to uprated / race), the front springs / dampers may require adjustment or upgrading to maintain balanced handling.
