Most common axle tube sizes ??


Well-Known Member
I'm curious what the most common rear axle tube sizes their are out there. Most weld on spring perches I see are for 3" diameter axle tubes. Do any trucks have 2.5" or 2.75" or bigger than 3" ?

I'm just curious on light trucks, not on Dana 80's.

Our rear end on our truggy was done by cone industries. It is a full floater 9" with 40 spline, and it is 3", 1/4" wall tubing. The 46 spline that Sandy does is like 3.25 or 3.5" and wall thickness is either 3/8 or 1/2.
