The rear shocks could be a big part of the prob, there dead. Thanks, Didnt think they could matter but it makes sence.

Ill be looking at Teck Wiki for shore,
Is a shame i'm having dificulty uploading pics, her ass was about 150mm lower than standerd, looked grate, the ride wasent, so i lifted it up about 75mm and the ride was better but stil bouncy. (Useless info)

Look in the Tech Wiki- category Suspension, Anti-Tramp for some ideas to combat wheel tramp. Also make sure that your rear shock absorbers are in good shape.

tramp rods and new good quality shocks will fix ya up

It bounces all over when i take off hard,(I like doing that!) Its like the rubber grips to much on the tarmac and starts bouncing (very irretating) need to get the power on the track and not the springs???

Sounds like it is to stiff, you say it has grip so you need to get some compliance in the suspension. lowering the rear should help, strange as it sounds the sandbag idea is a good start. Put 30 to 40kg at the back of the tray and give it a try, at least it is cheap and will give you some more information.

Dont mind roadnoise, plan big sound, havent seen brass buses, but i havent seen everything. Sounds lekke could you send me a pic and some spec on what brass.
Lowering blocks, Jes, but only 25mm, leave springs changed to get that ass down. Was thinking of taking it out to get the tracting sorted, the nose is down so i have to lower the rear to match.
Have downloaded some pics on rear axeals but cannot upload them here??

in 1200 utes you can make traction bars that are over the top of the diff and mout the the frame under the tray.

do you have lowering blocks? these will not help.

Also new urethane bushes or even brass bushes will make road noise a little loader but help reduce this problem.

Anyone? any other ideas or sites i can get some info?

I already have wedges between the diff and springs. makes a difrence not what i want.

I chect out the site you recumended, The first pic is what i was thinking, but it splits left and right.
Again i dont want to remove the tank. That is why i was thinking of one bar??

Check out hte McDonald Bros website for some ideas.. A lot of different rear end set up pictures there.

The wishbone might be something similar to what you are talking about?

Try adjusting the pinion angle. typically done with wedges where the live axle mounts to the leaf springs...
