BlueCords&Chevys

Silverado Double Cab 4x4, All-star Edition w/ Bose stereo, heated bucket seats, and machined 18in aluminum wheels....with crappy Goodyear fuelmax tires. This was taken before we had almost 2 feet of snow up in Fairbanks, AK. I cant wait to put a Rough Country lift and bigger tires. I want to stay with the stock rims (budget reasons and they don't look too shabby imho) and I have the 3.08 rearend. What all would I have to do to correct the speedo? Take it back to the stealership? Oh by the way, I walked away with the 7 year/ 100k mile warranty for almost nothing and free, full-synthetic oil changes at any Lithia Chevy dealership for the life of the vehicle. BAM! Plus i got $3500 cash back and a $5000 trade-in on my '04 Envoy XL. She's gonna be purty.....
