Just jumping on board to say what I did with my 800 Trail.

I used the parts of a rzr 2" lift for the rear only and adjusted the Elka stage 1's preloads all around to achieve 10" of clearance at either end. With with the 75 pounds or so of box contents and extra gas I feel compelled to lug around with me, I didn't have enough thread left on the rear shocks preload rings to quite get the ride height that I was looking for. The front Elkas have plenty of adjustment range and didn't need the lift plates. The rear though needed help, thus the lift plates and then backing off the maxed out preload until the desired right height was reached.
I didn't want to actually 'lift' the machine so much as to get enough clearance so that the skid plate isn't ringing off everything on the trails.
I went by a local dealer a few times now and measured the clearance of brand new Trail 800's on the lot, and they sit with no occupants, with 8.5 inches of rear ground clearance! When I had 8.5 it was hammering off every embedded rock on the trail.

I went with 27" tires (1" over stock)
I do a lot of technical and washed out, seldom traveled trails and I don't want to compromise stability. Though it's surprisingly stable as equipped I have an idea that EX and Trail alike both suffer stability loss when owners start jacking them up vertically. I figure there's no need for that as long as you have reasonable clearance and you employ a good skid plate like an Iron Baltic or a Ricochet. I have the Ricochet (Iron Baltic didn't make a plate set for the Trail when I needed one) with the HDPE center skin and I've beaten that thing like a blacksmith beats his anvil, and it barely even shows.

That said, with judicious picking of a line, it doesn't hit bottom very often now.

I don't want to make the SXS ride any higher, this setup seems to work fine for me. I like hearing about what others have done though.
