Correcting drive line angles

[thearborbarber]

I have a 6 degree angle at the transfer case and 16 at the pinion. I measured the length and height of the shim rough country put in the rear spring pack it's 4.5 inches by .75 inches. Using inverse tangent that's an angle of 9.5 degrees. There is an overload spring above the shim and together measure 1 1/8 inch. I am thinking about taking both the shim and overload spring out and putting in an easy inch zero rate spring. The idea is to retain the same ride height and drop the pinion angle closer to the transfer case angle. Am I in the right ball park?

if pulling the shim gets the pinion to match the Tcase, then cool. Pulling the overload and adding the zerorate sounds fine, as long as you don't haul heavy loads or flex the springs way past flat. Bumpstops are a good thing if you aren't running overloads.

Done deal now. I took the shim out and put in the easy inch, leaving the helper spring. Worked perfect. Future rough country users, take the shim out on you suburban lifts. Causing more problems and keeps a person from doing it twice.

I got the easy inches from DIY4X. Quick easy ordering and shipping.
