The pump on my truck has been making noise for a little while now. I got a trail ride in july so I would like to swap it out before then. Now do I just get a new stock pump or one of those aftermarket high flow pumps? My brother has the AGR super pump on his truck and he can turn 46s pretty easily (with out hydro assist). But his pump is several years old before AGR started going down the $hitter. I currently don't have hydro assist but its something I want to do in the future. What do ya think?
