Suspension - we are looking at the EVO PRO Stage 4. Is the install similar to the JK in regards to shock relocation mounts in the front and Rockstar's in the rear?
Not sure never had a JK - Front has new shock hoops at the frame and relocation brackets at the axle. Rear has added gusset at the frame & shock skid plate at the axle. Fairly simple. Hardest part of the coilover install was probably trimming the pinch seams above the rear shock to clear the new bracket, had to unhook the gas tank filler neck and hold wires out of the way on the drivers side. Feel around on top of the factory spring buckets in front before adding the EVO CO bracket, one has a wiring harness in the way and the other has a rigid brake line routed right in the way. I almost screwed that up.
King Bump stops - I assume it goes in the same location and you cut front bump and drop in?
Yup, cut the factory bump and thread them in, I got mine from Polyperformance & they did not come charged. Something to keep an eye out for.
Driveshafts - Sine we are thinking 37's and C/O should we just jump straight to 1350 JE REELS or will the stock drive shafts be ok for awhile?
I think the CO kit recommends front shaft or limit straps, I did long arm so just a little different. The limit strap kit is several hundred dollars you could apply towards the new shafts.
Wheels - Because of the C/O and most likely going to run a 37x12.5 tire should we stay with 3.5 backspacing or can you go to a 4.5 to 4.75 with the JL Rubi front 44?
Yes, 3.5 BS for the CO setup, I had to buy spacers for my 4.75's to fit. Also before switching to the PRO LA kit my tires were rubbing the control arms when turned to full lock with the 4.75 BS wheels.
