Almost figured as much. You did a VERY nice job!! How did you figure the length, if you don't mind my asking?All me. I just drew it up and started looking for parts. No kit at all, I got the parts from Poly Performance.
The top heim joint is right hand thread and the bottom is left hand thread so I can preload the bars for either drag racing or sled pulling.
I've heard that about matching the driveshaft also. After you've played with it a while, let me know how it all works out, empty and with the 5er.I talked to Bean and a few sled pullers about the length. Some said to try to match the angle of the drive line but that would end up with about 10' bars. Some said to put the frame mount between the doors. So I found where the frame is at its widest part which ended up between the doors(85"). So I went with it. I will see what kind bind, if any, there is when I throw my travel trailer on. If it binds too bad, I will take them off for towing and put them back on at the track.
It is all a matter of geometry and I hope I got it right. (If the angle of the bar is at the correct angle) when the rear of the truck squats the rear end moves back with the shackle. The traction bar is going to lengthen as the bar flattens under load, essentially making it longer and (hopefully)matching the same change in length the axle changes. I have only played with it a little under light loads but my truck does not squat, I have air bags to maintain the current ride height. I will have to see how it handles towing a load. I mainly need them for racing and pulling but they look cool driving around the street as well.how are you keeping them from binding when the rear of the truck squats and pulls the axle???
