Bill Creer's original thread mentions fitting the assistors with the wheels on but I think this was with 15" rims, yours and ours have 16" ones. Having had a quick look at the front suspension, there's not a lot of wiggle room as the coils are right up the top under the arches. So it might be a wheels off job but will ask Bill just to clarify.

I decided to have a look at the spring assister's for my van , but all the info I could find on them suggested that they where for rear suspensions , so I emailed the manufacturers and this is the reply I got ;


Good morning

We do not recommend fitting them to the front of a vehicle. Although we have heard of this being done.

Yes mine are 15" rims. If you managed to measure the space between the coils with the wheels on then there should be enough room to do the fitting. It's worth a try to save you the effort of removing the wheels.

No turning back now lol. Ordered a pair off Ebay today http://www.ebay.co.uk/itm/One-Pair-O...sAAOSwQJ5USRE2. Hopefully get them fitted next weekend (7/8th May) when I can get the MH down off it's front ramps and maybe a quick test drive after. If not able to get out, first outing will be mid June .

Well, they're fitted, easy peasy really. Seriously, it took longer to get the two 8 tonne bottle jacks out, jack up the MH and put the jacks away than it did to fit the rubber coils -simples. Left the road wheels on, as when the front end is raised on the jacks, there's more than enough room to get into the springs.

Forgot to take before and after pics of the ride height/clearance but looks like it's up by about 1.5" (as Bill Creer mentioned). First outing will be in mid June - will be taking bottle jacks with us just in case it all goes tits up and have to take the rubbers out on site lol.

Well that was £33................................

Well spent . Currently running tyres at 65psi on all six wheels, the same as before the assisters were fitted. Much less harshness on the front end on your average road but potholes and the like still crash through the MH. You know the sort, the ones your car just shrugs its shoulders at. Even cats' eyes before the assisters would produce harshness in the cab but no more and the MH just glides over them. No difference in handling or stability over 40 miles of twisty A and B-roads.

Overall, very happy with result. Will post a pic of the front end clearance when we come off the levellers in the next few days.

Happy days

Some pics showing the ride height, now at 77cm from ground to highest point on the wheel arch with the front axle at 2020kg.
