Going to be installing my Dynatrac axles but they were used for coil overs...have to cut off the bump stop pad and weld coil perches in place...How do i find out the exact location? I know the angle is different and full droop and at squat...

 

Any Ideas???

 

Connect the axles without the springs and cycle it. Droop it and stuff it. Determine your mounting points from there, tack weld the perches, install the perches, install the springs then cycle it again. If it's all good, complete the welds.

You can always look at a stock axle and break out the measuring tape, pen, and paper and use those measurements as a starting point (at least for the rear axle). Keep in mind that based on the planned amount of lift you'll have, you may have to rotate the axle(s). Since caster is probably built in to the front axle, I'm sure you can get info from Dynatrac directly regarding their spring perch mounting points for it as well as the rear. I'm no master mechanic but it doesn't seem like rocket science.

I would think at ride height, you don't want the springs to be bowed.

Cut of what you have too and set up the axle at ride height, this is where you should mount the lower perches. This way you get the angle right and they sit straight where the jeep is most of the time. No need to cycle the suspension. If using lower perches like from JKS that has a U bolt you can instill them loose and easily adjust them with the coils installed, just support the jeep at the ride height to keep it from moving.
