Stop axel tramp, basicly what you guessed, the tramp bars give steady pressure to the diff, pushing the tires steadly to the ground as such.. on quick take off...

Yeah very effective.. They came on the car but i have now taken them off while replacing the diff, to fabricate some sets for others..

what do tramp bars do? I thought thats where prostitutes like to hang out nah seriously what do they do? my first guess would be to stop the diff from spinning down when you drop the clutch with mega horsepower at the sticky hot tyres?

Simple and effective!! best way.. Did you make them yourself?

Bigger pic..

Here is a pic of the tramp bars on my ute, i received a few questions about them, so i thought i would just show a pic.. would be relatively easy to fabricate i recon.. they work great!.. Cheers.. sorry for the small pic, if anyone can put a bigger one up i will email it to you..
