Why choose LEDA?

Design, Fabrication, Restoration and Installation Experts

Tailor made to suite your cars requirements such that the middle setting is matched to your suspension design and spring rate, for dry settings. Every click of adjustment is a meaningful damping adjustment position where both rebound (extension) and bump (compression) damping are adjusted simultaneously.

Every damper is individually and rigorously dyno tested, every set of LEDAs is matched in both rod speed and adjuster performance. Superior materials, design and construction. Dual acting adjuster that adjusts bump and rebound at the same time and retains the pre set ratio of of the two whilst doing so.

Damper design Fundamentals

We design our dampers to have the correct damping rate to control the spring that is fitted to the vehicle in dry conditions with the damping adjuster in the middle of the range where fitted.

Fixed damping is similarly designed to control the anticipated spring rate.

Typically, the calculation for this is as follows; spring rate seen by the damper x conversion factor = damping force required to control the anticipated linear spring rate over the rebound transition valving phase of rod speed.

Common misconceptions

Common misconceptions and questions

Gas pressurized dampers are better

Gas pressurised dampers were originally designed to reduce the number of components required, and complexity of assembly when making dampers for mass production, This then got seen as the latest technology and that twin tube oil filled was not as good. THIS IS NOT THE CASE

For the same outer body dimensions oil filled twin tube dampers will inherently have more oil capacity as there is no volume taken up with a dividing piston and gas. Having a large capacity of oil is very important as the oil is what soaks up the heat produced by the damper in service and is what conducts that heat to the damper body to be rejected to atmosphere. We have tested same sized body volume dampers back to back on our dyno (gas pressurised vs twin tube oil) and the gas damper quickly overheated and damping force was drastically reduced as a result.

Another drawback is if a slight leak is present the gas will force the oil out of the damper rendering it useless in a short space of time.

A gas filled damper will add to your spring rate, this should be taken into account when specifying springs.

I need a dual adjustable

Once you have chosen what discipline your vehicle will be used for the ratio of bump to rebound adjustment should always remain fixed. Our dual acting adjuster adjusts bump and rebound at the same time and retains the pre set ratio whilst doing so and negates any double damping adjuster overlap thus making adjustments simpler and more positive

Why don’t we use aluminum bodies?

In order to achieve the required strength the alloy bodies have to be thicker than steel which results in two things, a body that is has a minimal weight difference to its steel counterpart and a reduced oil capacity.
