Tembrens or Air

After reading numerous posts and reviews, I went with the Timbrens for my 2015 Ram 2500. I received them yesterday afternoon and had them installed 30 minutes later...so easy, 2 bolts on each side is all it took. I did not use the included spacer as it put the bottom of the Timbren too close to the axle stop. I won't know how well they work until the beginning of April, but I am hopeful that they will take out the 2" of dip that my 5th wheel puts on my truck's suspension.
