So my blazer now has a 5.3, 4l60e, np205 and 35s on 20 inch rims. I do not off road it but I want to use it to pull my car trailer and eventually I'm hoping around a 24ft boat. Currently both axles have 3.73 gears which I was hoping to change out this winter for 4.10 or 4.56 gears and add a posi.I need to figure out which axles I'm going to use first and this brake thing has me leaning back to the originals. Also I do like to take it on road trips. So far I've done a few 3hr trips but hoping to take it on an 8hr road trip
