Great 4 x 4

Vehicle2003 Chevrolet Silverado 1500HD 4dr Crew Cab LS 4WD SB (6.0L 8cyl 4A)
ReviewThis truck is great. I traded in my
2002 Z71. The power in this truck is
incredible. However, the gas mileage
is not impressive. I put a Magnaflow
Catback exhaust to increase gas
mileage and it did not work although I
did get 20 more horses. I am going to
put a K & N filter. I heard that
improves the gas mileage. So far I
love the truck!
Worst FeaturesPut a light under the hood and try to increase the gas mileage.
