For a daily driver I have had good luck with Bilstein shocks. I think most any higher end shock would do the job.
I agree. I just got a set of Bilstein 5100s for my dually & they are great! I had them on my last truck as well. I would get them again when the time comes. Many here have used the 5100s and will agree with me.
By the way, you are describing a pretty heavy load & it seems as if you are asking about which shocks will handle the load the best. Shocks ARE NOT a load bearing component of the suspension. They dampen movement in the suspension in order to improve ride, handling & retard wear of the tires & other components. PERIOD! If you need to level your truck due to the load then air bags are the way to go. I use the Firestone Ride Rite system & Iím very satisfied with it. Iím sure that others will jump in here with great advice as well.
Good luck & let us know what you decide & what works for you.
