Hi guys, I have a GMC 2500 5.7 with dual Flowmaster, "Street Tech" performance module, new Dick Cepek foglights, super heavy duty Turbo 400 3-speed automatic. The transfer case is the NP 241 with the low planetary gears. The axles consist of the factory GM corp 14 bolt semi-floater out back with 4:10 gears, and the GM corp 8 lug ten bolt up front also with 4:10 gears. Complete with dual Rancho 9000 adjustable shocks up front, and single R9000's adjustables in the back, the truck rides super smooth and sits just right with the NEW 33" BFGoodrich Mud Terrains wrapped around Cragar American Racing Outlaw 2 aluminum rims. Has a brand new headliner and custom double-stitched leather wrapped dash pad and factory over-head console. Alpine stereo and brand NEW Kenwood 6" speakers in all 4 doors with tweeters mounted high, just ready for my Sirius subscription! The guy I bought it from even had a print-out of the compression test he ran, which showed even compression over all 8 cylinders. It gets about 14 mpg on the highway but with the low-geared 3-speed, I don't plan on running it over 60 mph on the highway. I filled it up with some good gas and dumped in some Marvel Mystery Oil to burn out any carbon and work on the rings a little. My brother and I spent 14 days in her driving from San Diego to Cabo San Lucas in early Januray and would like to do it again soon. She performed flawlessly!
