Got my truck alignment checked the other day and finally got my 37s on. Alignment went great. Caster angle, rear driveshaft and axle centers were dead on using the measurements RockKrawler gives you in their instructions. Toe was perfect. Thank you to Eddie, I watched your video on the Synergy Steering products and did my measurements the same way. When I installed mine I gave it a 1/16" toe in and it ended up being perfect. My alignment shop only had to adjust my steering wheel slightly. Tires are 37" Nittos on KMC KM544 wheels. Wheels are gray with black trim rings. Fits really nice, 4.5" backspacing on wheels. It has a wider stance than my JKU on 37s. I'll have to get a pic of them side by side.
