GS430 MK3 UZS190

[Socket786]

Hello All

I am having problems with my existing rear suspension due to load ie two lpg tanks, petrol tank and passenger use.

Is there anything on the market that's slightly uprated to take a heavy load.

Thanks

There are three ways of tackling the problem.

(1) The cheap but effective way using rubber spacers between the loops of the rear coil springs. Many caravaners use these to overcome the rear end sag when towing. They are surprisingly effective, cheap, easy to fit, and are available from most caravan parts suppliers.

(2) have stiffer springs made, and fitted.

(3) Replace rear springs, and shock absorbers with adjustable coil overs. These are available from car tuning specialists.

Just thought of another possible way of uprating the rear suspension. Check to see if the rear springs of the GS450H will fit the GS430 shocks. The GS450H carries the traction Battery in the rear so the springs carry more weight than the conventional GS's.

I can measure the unloaded dimensions of a GS450H spring if it will help.

Many thanks for replying.

I have been online and there are "COIL SPRING ASISSTERS" on the market. Question is what size is required for the GS as there are too many sizes to pick form.

Also made contact with a company that sells springs. Fingers crossed.
