2004 GMC Sierra 2500 4dr Extended Cab SLT 4WD SB (6.0L 8cyl 4A)


Great truck, still getting used to the
new front end grill( I liked 99-02 best)
I previously owned a 2000 z71 sierra
slt. Just bought 2004 SLT 2500 crew
cab 4x4. They dont include under the
hood courtesy light, they eliminated
one of the cigarette lighter power
input. the 2004 has 6l vortec which is
a huge pig compared to 5.3 vortec in my
old 2000. the new computer stuff is
pretty cool. I am getting on average
10mpg on the 6 liter, I used to get 18-
19 on the 5.3 motor. The first thing to
go will be the air cleaner swap with an
Air aid or K&N type of element.
dramatic horsepower and fuel economy
increases should be expected.

Best Features

DVD player, 4 doors,

Worst Features

It seems that 2004 GMC's quality has gone down a bit from my previous 2000 year model truck, gone are many things that I thought would be standard in the newer models, RAM air would be great, more fuel ecenomy, huge Fuel economy difference from 2000 5.3 to 2004 6.0
