Stiffening suspension

Does anyone out there think it is necessary to beef up the rear suspension when carrying a demountable? I have mounted my Northstar 700 on a Hilux double cab and while it drives fine i do notice the bonnet is "up".

People have added cart springs with extra leaves that only connect when carrying extra load like a camper but typically most owners go for a couple of airbags that go in centre of spring (roughly where bumpstop is)
plenty available but Marcle have some; https://www.marcleleisure.co.uk/air-sus ... wards.html

sort of DIY but better done by garage with air tools


Inflated to around 20PSI these will correct headlamp/bonnet angle and provide a much, much nicer ride

The alternative to "air suspension" are mechanical spring helpers. There is a thread on these boards on this subject.

In favour of mechanical spring helpers is - they are simple, low tech and durable.
However the air suspension units are infinitely adjustable, but that rubber and road salt and crud does mean they have a limited life, and relatively they are costly!
