I have a 2005 2500HD truck and the trailer in my signature, can anyone recommend the best shocks to get for this set up?(Still have the originals) Thanks any info appreciated.
Oh man still running the original shocks (sorry to hear that...) they have likey been bad for about the past ~10yr and are doing nothing for you. Factory GM shocks are garbage and don't last long.
Pickup a set of Bilstein 5100 (or 4600)shocks and you'll be kicking yourself for not doing it sooner.
