Hey Roy, that is quite the truck! Since it is a dump truck you will want the higher capacity from the Timbren Suspension Enhancement System # TFRSDE. This gives you up to 12,000 lbs of additional support to handle those heavy loads and reduce that rear sag you have now so you stay level.

Air bags are nice for a standard pickup, but the Timbren SES is the better option here. They will engage right away, and you also don't have to worry about maintenance or adjusting the air pressure.

What are you hauling?
