If the ride is that hard it's most likely cos the springs etc are biased towards carrying heavy loads, and you just don't have a heavy enough load on it so it just isn't going to flex! While loading it up some more will make it work a 'little' better, that's not gonna be the greatest idea for a whole lot of other reasons and when it comes to the crunch, heavy duty leaves that can carry loads may not ever give you much more flex, that usually takes a whole different leaf design & pack compilation.

The only things you can do to get better flex is either remove one or more leaves from each spring pack to reduce their stiffness/load carrying ability (& hope you don't lose any height & that you do gain flex - & that's not entirely guaranteed) or toss those springs entirely & get spring packs that are the same height but rated for lighter loads & more flex (& then hope they don't sag over time or under heavy loads.)

Do you carry heavy loads often? Are heavy duty leaf packs essential to you at any time?

Are the shocks the right lenth? Flex it up and check if the shocks are the right length. Springs might also be the wrong length and have nothing left to give. As above spring rates and shackle angles might be totally wrong and not want to move it all. Are you trying to carry big loads too? It might take a bit of mixing and matching to get good flex, but it can be done.

Don't really carry big loads only camping gear ect..
I have hardly used the suspension as I put it in the truck n crashed n only just got back on the road
The kit was about 4000 n it's a 4inch flex kit n I got the proper shocks for the kit
Should I take sway bars off ??
Thanks

Take the extended shakles off and put the stock ones back on. That will correct your shakle angle to start with and let your springs actually do something. How do you pay $4000 for a suspension kit?????

The sway bars won't have anything at all to do with the ride being hard, and they probly won't have a heap to do with the lack of flex if they are standard sway bars. You will need to keep them on to remain roadworthy, but once off road disconnecting them isn't an issue, altho you probly won't get a heap more flex from what you are describing.

Shocker rates don't actually have a heap of impact on Heavy Duty leaf spring flexing, but shock length certainly can, as can extended shackles/wrong shackle angles/incorrect spring lengths - but I still think your main problem is simply going to be spring rates, you've just got spring leaf packs that are way too heavy for what you are carrying - a common mistake made by many 4WD'ers where they mistakenly equate Heavy Duty & 4" Lift with meaning 'massive extra flex', and it just ain't so!

Question, when then lift went in, did they extend the bump stops too??

If the suspension cost that much then maybe your best bet would be to sell the whole lot for whatever you can get for it and use the proceeds to get a proper 'flexy' suspension that's been designed & put together to suit YOUR articulation & load carrying needs, one that isn't ott 'heavy duty' or even necessarily all that big a lift - lift height only needs to be big enough to fit whatever size wheels you want to run and allow for their articulation. Lift size needs to be matched to the wheel size & bump stop length, even with a big lift you can fit too big a wheel so that to stop the wheels hitting things the bump stops need to be extended so much that you actually end up with LESS articulation than a stock suspension.

Oh, and don't forget it usually takes a fair bit more effort (& expense/attention to getting everything right) to make a leaf sprung suspension flex/ride like a coil suspension will/can. ;)

Good Luck

the general replys have been the springs are to stiff,

I have had cruiser utes for 15years now, lots of people say they are a great 4wd,

I say in some ways they are not really, they dont have good suspension flex so lift wheels easy, thats what lockers are for!!

But you can get good heavy springs for them, put a heap of stuff in the back, like boats, bikes heaps of fuel etc, one tonne plus comfortably and do extended trips.

turning a 75 into a good flexing unit, while empty, will require some specific setting up, as has been suggested, but then wont carry a decent load if required.

its all a compromise

I have to agree 100% with Bala as I have owned utes for some 25 years.
Tell me how many leaves you have in the fron and back please.

Hey Lynch, you have set yours up perfectly by the look. Not many utes can go bendy like that !
Well done mate.
Ahh on a closer look....you cheated !! I see the disconnects LOL.

Are Revolver Shackles illegal in Qld?? How do you find them on and off the road? Thinking about using them in my 75
