2006 GMC 1500 4X4 SLE Z71
By David Russell on


2006 GMC Sierra 1500 SLE1 4dr Extended Cab 6.5 ft. SB (4.8L 8cyl 4A)


Very Handsome truck. Price was very reasonable ($6,000 less than comparable Titan)Combination of performance and fuel economy very good for 4X4 large truck category (17 mpg avg.). Only two complaints too tall gearing 3.42 gears in all 4X4 trucks I looked at;thus towing is kinda difficult. Truck feels like it is in second gear when starting off. Corrected that problem with 4.10 gears. Now truck pulls hard and feels more powerful than the titan I drove, and also my dad's hemi ram. I also have a programmer intake and exhaust. The truck with 8" lift and bigger tires still runs around 7.2 seconds to sixty. Stock it could muster only 8.8 seconds to sixty. other problem no grab handle for driver.

Best Features

Tough looking exterior, smooth transmission, motor has more power than reviews whould lead you to believe. The next time you check out a new truck comparo check the tranny and rear end gearing for all the trucks and you will discover that the titan, hemi ram and toyota all have much lower gearing.

Worst Features

make 4.10 gears an option for non vortec max models.(I have still not ssen one yet) Please do us all a favor and put grab handles in all 4X4s driver doors.
