Thanks for the support guys. If I have learned nothing else in my many years of life it is the need for friends and the best friends are the ones that stay with you when you need something. ColoradoK5 friends are the best kind. Rene and I put our heads together and worked out this design for our own trucks without consideration to what it would cost. We just wanted it to work and work well. With that said let me tell how its made and then you will understand. The two plates that bolt to the rearend and the pinion are 1" steel. They have a .50" steel bar mounted in them that the roller turns on. The steel tube roller that is welded to the end of the long tubes has a UHMW bushing that is machined from solid stock (no cheap poly bushings) and this is the same material that is between your spring leaves and takes so much punishment. These rollers allow the vertical movement of the axle. The long tubes are 1.50" x .375 wall DOM tube and the lower tube is positioned beside and just below the drive shaft to protect it from rocks. The other end of both upper and lower tubes are threaded with a 1" thread 3.50" deep into the tube. This was single point threaded in a CNC lathe to asure straight precise threads that would not bind and provide enough adjustment that it could be fine tuned after installation. The eye bolts (not cheap heim joints) are made from 1.625" 13-8PH stainless steel and heat treated. They also were threaded in a CNC lathe to asure precision fitting to the bars. These threads are what allows the articulation of the axle. These eye bolts attach to the shackle with .750 diameter grade 8 bolts, the shackles are .750 thick steel, the pivot tube at the cross member is DOM tube and again it is lined with UHMW bushing to take the beating that I know it will get. The cross bar is the same 1.50 x .375 DOM tube used else where. All together the material alone costs about $300 and the rest is labor. Below are the parts that make the entire unit. Untill we make more than 10 units at a time we loose money on each unit we sell.
