i know an lsd would be the best option but it would probly be worth more than the car!

 

locker is cheap and eazy

In my motorkhana car, I have a cig-locker, super heavy duty XD springs, VL commodore shockers, and standard sway bar. I get absolutely zero tramp. So if your not too worried about comfort, try some up-rated springs.

Get a less stickier tire, heavier duty shock, or delete the locker, either that or learn what a locker will do dude, you realise a locker shags out your trailing arms and every bush in the rear end of your car,

SERIOUSLY WTF ^^^ i tried to help but you just seem hell bent on being a f'n tossa, a bigger sway bar is designed to stiffen your car more than a factory one to stop it from body rolling, i hope you find out a sway bar wont stop your shitbox from tramping it will make it handle better and not body roll as much but it will never stop a locked diff from tramping deadshit, school holidays again
