Although not related, here are a few photos of my single cab dually. I bought this truck as a stock 2500HD SRW fleetside a couple years ago and converted it over to a dually. It has a 5/7 drop with 2' Spindles, 3' keys, 4-5' hangers and 3' shackles. The wheels are milled 24.5 semis with 295/35R24 tires. The most recent changes are the Denali front end and the 99-01 Chevrolet HD hood modified for the GMC headlights.
