OME installed on 5th gen SR5 in march 2017
I put on the OME 2884 springs in the front (390MM) and 889s in the rear (390MM) today and it took my 2011 SR5 up 2.75" in the front and 3" in the rear. I have BFG K2O2s 275/70/17 with stock wheels and they rubbed the front wheel well with the steering at full turn and now they rub the back of the wheel well with the lift. Neither is very bad, so I am going to take the razor blade and trim the plastic on the rear of the wheel well.
I previously had 265/70/17 (stock tires) and they rubbed the front wheel well. Go figure.......
I like the lift, my wife, not so much, so I might be going to 2883 springs in the front (370MM) and 895e in the rear (375MM) I am running the OME nitrocharger sport shocks. I didn't do a diff drop and it doesn;t look like i need one, but i will check in a few weeks. I did put on light racing UCAs and the alignment came out fine.
The vehicle now drives like a truck - no more nose dive into the concrete on stops, or the bouncing when going down my curb, etc. Again, i like that, my wife liked the "boat like sensation".
