4 Wheel Drive/SUVs: suspensions, dana 44s, yj spring

Question
I am going to change out the stock axles on my 1978 CJ5 to Dana 44s front and rear. I'm trying to decide if there is an advantage to going with spring over vs the factory spring under. If so would it be wise to go with a wider spring like the 2 1/2" YJ spring?

I'm running 33" tires and have a 2 1/2" spring lift and a 1" body lift which gives me the height I need. If I go to a spring over application what if any spring lift would I need to get the clearance for the 33" tires?  

Thanks, Jim

Answer
Jim,

Jim,

As this is a controversial issue, since many drivers do not like the spring over, I am only expressing my personal opinion.  I have a spring over, and love it.  It is an easy way to get 5" or more of lift with stock springs (usually 5 1/2"), and increase your articulation.  The disadvantage of a spring over, is that you tend to get more axle wrap, which reduces the life of the springs.  You shouldn't need to add any more lift with the springs to fit the 33's.  As far as the Wrangler springs go, they are wider, but thinner, and seem to articulate more than the stock CJ springs.  You may experience additional bump steer with the spring over, but a shackle reversal in the front will help with that problem.  The Jeep will ride a little smoother with the shackle reversal also.  Spring overs are quite easy to install, and can be done fairly cheaply by buying the spring pads/purchases, and welding them in place yourself.  The major part of this, is to make sure that you have your driveline angles where you want them prior to any final welding.
