I bought couple things from rocky-road (locker and OME shocks) didn't have a problem but why not support SE. If you want to stretch you dollar a little further you can just get the springs since unlike solid axle suspension travel doesn't change when you put taller springs on independent suspension. That also gives you option to install better shocks like remote reservoir Bilsteins or something. If you plan to get a winch I would get heavy duty front and medium duty rear which later you could supplement with Airlift 1000 airbags or something along those lines if you plan to tow/carry heavy stuff. I've got those on my Gen 2. Ride height doesn't change and you can adapt to give load. Yes I know Airlift doesn't sell a kit for Gen 3 Monty but I worked with them to find close match for spring height/diameter/travel then only needed to manufacture adapters for top and bottom spring seats. There is body mount bolt sticking down at the top and hole in the bottom to clear. Rolled my Monty and all worked seized for obvious reasons. Still have those bags in my garage.
