For those of you with a 7" rear drop looking for a good alternative to bump stops, look at Timbren products. I chose their "Rubber Spring" A140-65. It is a 1.885" tall rubber bump stop that has a nominal weight capacity rating of 500 lbs, and has a bump load capacity of 900 pounds. Their maximum deflected height is 1.1875", which means your differential and brake line/hose brackets will never hit the bottom of the bed. I purchased the set for ~75 USD. Just remove your factory bump stop brackets with a plasma cutter or sawzall, drop a 3/8" bolt through the existing hole, and put a nut on the underside. With the vehicle on flat ground at ride height, there is 5/16" clearance between my bump stop and the landing on the axle tube.
This is a relatively simple solution that provides a good combination of load capacity (can still use a half ton truck like a half ton), and ride comfort. I have zero qualms throwing two supermotos in the back of the truck, or hauling a thousand pound load. If you have any questions feel free to shoot a DM. Just something I found and figured I'd share.
