Shockers & Coils?

[PeeBee]

OK, so they are set at the highest setting and still unacceptable? There are a range of shocks avail with different valve codes. I run Koni's for example and they are great. The ARB BP's are good I here. There are a range of suspension places to contact. they will probably/should ask you how much weight you have over the rear axle and at what speed you are travelling and what sorts of road conditions, corrugations/ lumpy roads with intermittent potholes, undulating choppy etc. If they don't ask these questions they are giving you a catalogue sales answer, so hang down on them and ring the next guy. I will PM my bank details next!!

At the end of the day its about energy transfer, nothing more. Stiffer coils will absorb more and deflect less, giving the shocker less time to react, bearing in mind its a tube filled with oil pushing thru disks with holes for metering. This another reason why shockers fail, as they get hot, the oil thins, the rapid cycling gives rise to aeration and the oil loses its viscosity, with air bubbles generated, the air being compressible and the oil not, so the performance becomes variable and goes downhill from there.
