Spidertrax has just released their full-floating rear axle. Very cool, not cheap though. It's a tough piece. We watched Eddie try pretty dang hard to break his on the Helicopter Pad at Tellico. It took a beating and didn't fail. Check it out....
http://www.spidertrax.com/fullfloater.htm You can't get 3.73's in it though. Just 4.63 and 5.13. You'd have to find a matching Sidekick front third member.
