Your set up is perfect. 2" of lift is great for 37's but on the other hand if you wanted a better ride the EVO plush rides are a great softer ride then teraflex springs. I went from a 4" teraflex spring to the 3" plush ride springs.View attachment 221460
I haven't noticed mine to be sagging. But I have seemed to bottom out a lot with them. As well as rub on my fender flares. I hate to trim my flares just yet as I really want to go to a 4 inch lift and 37s but will most likely have to run the 35s until they wear out. I feel like it will look goofy with trimmed fenders, a 4 inch lift, and 35s.
