Trailer leaf springs question.

[Ironman 4x4]

Hey Mate,

Unfortunately this is something that I won't be able to advise you of any further online, purely because it really does need to be physically looked at and measured. As stated above, if you measure up the leafs and find that they are within those specs that are advised, you should be all good. But you'll need to physically get under there and do the measuring up of the suspension.

This is the trailer, might need a better pis though.

Hey Mego,

That is a very light "Slipper" Spring setup mate. If your looking to use your boat trailer to carry a bit of camping gear and what not (I think i read that somewhere) then you really should be looking and replacing that set up with a eye to eye spring with a bush at one end and a shackle at the other. Get them load rated to 750kg at least, this might also see you need to replace your axle too and it this is the case then think about putting electric brakes on her while your there.

You really cant "Half do it" and i dont think your the kind of bloke that wants to half do it either.

The trailer is already rated to 749kg and I only want it to hold extra 100kg.
I am basically loading to under the max rating anyway but it does get the tyres close to the guards.

Really!! Wow, then they are the light side of that mate. maybe it is rated at 749kgs as getting it rated at 750kgs would have needed something further.

Not a fan of Slipper Springs. If it is rated to 749 then your axle should be fine, junk those springs and weld in some hangers at the back and fit Eye to Eye springs and be done.

well that's very new and very cool.. But i think the same thing would come about with this setup as with normal springs.. If your loading to the upper rating your increasing wear and will have to replace rubbers sooner, and if you go the next step up then you'll still have a stiffer ride once empty.
I guess if you wanna do it right, load her up and find a weigh bridge. Find your real weight.
Im still sticking with some sorta load aid, like air shocks, or even leaf bags like the use on vehicles. This way your springs will still work as intended with light loads, but wont take 100% of the heavy load.
Id go the shocks over the bags though so your adding some stability to the trailer. Your adding a lot of top weight and the little 650kg springs aint designed to dampen that sorta overhead load..
In the end it is your call and your $$$, im just think out aloud

X 2 wuth MR go see Scotty at that trailer place I mentioned earlier, they sell the lot plus you might be able to fit patrol rims on your Trailer .
If you want to meet there ,what ever yell out. Or we make a wiz bang boat trailer that'll be the envy of every one,

[threedogs]

IMO sell this trailer and buy an up graded one already braked, think it would be cheaper in the long run.
. KIS. Going through whole rego thing with pits etc will drive you nuts.

I really struggle Mick to see those springs coping with 750kg???

My gardening trailer is rated to that and has far bigger springs with bigger axle and 6 stud 4x4 rims and tyres and even with a tonne in the back the tyres only then get close to the guards.

I have only had that weight in there a couple of times thanks to dopey loader driver at the yard way over filling me and the drive back to the job was scary.

Brakes ain't needed if below 750. So best weigh it all first and then fork out $$$

And thats why it is rated to 749kgs

yep consider trading it in versus stripping the springs and axle off and welding on a new set. the new set will likely set you back $500 maybe?
