Sure is. Got the 5100's on all four corners and OME 886 springs. IMO, the spring rate on the 886's is a touch high. If you hit a dip a little too fast, the front end suspension bottoms out at full down travel instead of gently following the contour of the road. I can't comment on the 5100/stock spring combination, since I redid the entire suspension all at once - Camburg UCA's, OME 886, Bilstein 5100. I haven't done anything with the rear except to put new shocks back there, but I do need to do something to increase the load capacity. The added weight of the tent and other stuffz plus all the kit in my load plan makes for a tail-draggingly good time in the woods.
If you plan on carrying a hefty load, which, as it turns out, I do, then do something about that. If you don't carry heavy loads, then the front end suspension upgrade levels the truck out, nicely, without any work on the rear suspension. I haven't the foggiest idea where to start when it comes to researching which AAL kit I want to use, so that's sort of in limbo until I find a start point.
