It's over 3lbs per axle on a 35 spline axle.
One of the best ways to loose weight is lite weight brakes and rotors. And make sure you have no or very little drag on the brakes.
I'd be willing to bet some trucks have as much as 50lbs of drilled weight taken out. I've seen frames with more than 600 holes in them. All that extra weight can be moved towards the rear or placed where you want it. Lighter doesn't always mean faster, (in mud racing anyway) but being able to put weight where you want it is an advantage. Our rules allow you to build a frame out of .083. My truck is a factory frame (with a backhalf and a front half) which means it's a heavy frame compared to the newer truck. And mine is also a steel cab and front clip. I'd love to have a full fiberglass body.
Also keep in mind a lighter vehicle is easier on parts to.
