opinion on Peterbilt suspension

We haul 97000 gross with our 05 with flex air every day. Have for almost 5 years, all on road miles, but has been perfect. Nuthin broken or any other issues. Rides better than my 99 low leaf. Good luck with it.

 

last winter I was hauling about 140k lb gross off road with an 05 w/flexair. it handeled it about the same as lowleaf. it certainly is more durable than low leaf in this application. we haul that weight on a regular 3 axle truck (1 steer 2 drive axles) and a 4 axle trailer (one lift, 3 solids). when hauling those weights it was a little spongy coming out of the bush (with the air lift up), but it never broke anything. and it seemed to handle it ok ish on the highway.
