Raising Camper Suspension?

Gday,
Yes you can put your axle under the springs to raise it. The only problem will be your anex wont touch the ground properly if it is a full one.
Cheers

100mm axle sounds a bit strange........even for a import. If it is a 100mm pipe I would change that to a 50mm axle which could be a offset axle with a 4inch rise that would raise the chassis and you can keep the axle on top of the springs.
It is not as expensive as it sounds. Depending on how handy you are.

G`day Tim,
Probably 2000 klm or more ago I changed the axle on my Windsor caravan from over the springs to under and gained an extra 100mm.
Never had a problem with it.
cheers

Tim not only do you gain the 100mm of the axle you also gain the thickness of the springs as well which may be another 50 to 80mm. The centre bolt in the spring pack will need to be inverted as well as the axle & I think from memory I had to modify the U bolt mounting plates slightly as well on mine for some reason. It jacks them up along way otherwise the trailer handles fine. For slightly less lift longer shackles or welding a packer on the front spring mount may be another option.

We've got an old (1978) Jayco Dove camper with 7 leaf springs, which I had put over the axle in 2002. Since then it seems to ride better behind the veh.and certainly feels better to tow. Go for it.

Me, too ............ I done it as well !!

Gave me extra clearance and allowed the fitment of the larger Troopy rims and tyres [ after changing the hubs, of course!] which was the primary intent.

A point to note iffen it is applicable ....... iffen you [he] is fitting bigger wheels as well, on mine the wheels projected laterally approx. 50mm beyond the mudguards, illegal as well as unsightly and dangerous { flipping up stones, etc...}.
An oversight on my part ........... caused a bit of mental anguish at the time !!
Solved it by fitting rubber extensions [from eBay} to the guards.

Tows well and have had no problems at all ......................

May need to flip the axle end for end.

Some axles are set up with slight toe in for better towing.

So if you flip the axles to the underside of the springs, you get toe out.

Turn the axle end for end and you get toe in again.

Anyway, simply check for toe in before you start :o)

Of course, if you just leave the axle as it is , and place the springs over it, not an issue. depends if there is a locating lug on the axle.

Thanks all,

Will give him a hand Friday with the SOA conversion.

Ok coreect me if Im wrong but a 100 mm axle even if hollow has a centre line that is at 50mm above the spring pack. If you invert that you will now have a centre line 50mm below the spring pack.

50mm above plus 50mm below plus the thickness of the spring pack 50mm-ish....

Gives a total lift of around 150mm or about 6 inches??

Is that the height lift you were looking for?

As for the conversion as long as you can extend the brake lines for hydraulic or extend the cables if mechanical I dont see any problems.

There is no real torque reaction you have to worry about (a bit when you brake) nothing that could 'wrap' you leaf springs.

If you were only after a 25mm lift you could fit a 50mm square axle ontop or 75mm lift fit 50 mm axle SOA.

Anyway as the rest have said canvas doesnt seem to be a worry and apart from stabilzers legs maybe not reaching the ground....an easy conversion.

All the best

Matt.

I went the spring over and a new 50mm sq axel, with nissan rims on the boat trailer in my rig pics. only problems I have had are mudguards cracking due to vibration (solved to a certain extent with straps to boat) and took out one of the light poles at the back on a tree a couple of weeks ago.

Its been to kalumburu and other off road runs to rivers etc with no problem at all. This is with just the origional slipper springs, which I will replace one day....maybe.

Cheers Andrew
