Here is something a lot of you guys using a 2005 and newer Ford F250/F350 Superduty or 2014-up RAM 2500/3500 Axles will appreciate.
 
This bracket will mount to the factory radius arm locations for the upper and lower mounts on the axle. 
 
They are designed to use a 2" O.D. tube and are made from 1/4" thick plate, laser cut and CNC pressbrake bent for perfect fit.
 
Sold as a pair so you will want to buy 2 sets to complete an axle.
 
They come unassembled and require welding. 
 
The brackets have a 18mm hole and will fit 14-up Ram and 05-up Ford trucks.
