I did the Coffman rs1 diff swap on my 18 xpt.
On the turbo I would not recommend having a inbound mounted winch, Joe said it would be tight. Its tight! Especially with the extra hoses for the intercooler. On your machine it should be ok but I would mock it up and decide from there. I'll be moving my winch to a winch bumper
The swap is pretty easy all in all, as long as you have a grinder and a reciprocating saw.
I did end up missing some hardware ... a washer and a low profile nyloc nut that was impossible for me to source. (Thanks Jeremy for not shipping that out like you said ya would! Appreciate that buds)
The other caveat would be changing out the steering rack if the need arises. You may have to pull the diff to get to it, real estate is at a premium around that area. I haven't crossed that bridge yet though.
The blue arrow area I had to keep add a little more clearance than in the instructions, after i did that the diff rolled right in. The square blue box is the bolts to the steering rack that may prove to be difficult to reach after the swap
All in all I would recommend the Coffman kit. Fitment and machine work was excellent. Their packaging could use some refinement...
I would ask that they ziploc all the hardware so it's not just bouncing around in a box doing the USPS plinko and a prayer thing
