Denali's are decently quick stock, but there are faster trucks out there stock for stock (tundra and ram). What makes them dangerous is their damn after market. They are a few bolt ons and tune away from a 13 second time slip in any configuration.

You guys see that new commercial where the GM is pulling out a Tundra and RAM out of the mud chained together? Too funny. They may be the truck to have as far as modding goes, but i wouldn't use any GM to pull anything unless it had a diesel and an allison trans.

 

My uncle just paid $65k plus for the new 6.7L Ford Super Duty Diesel. He was going on how better the specs were than every one else. I told him in a month Chevy will top it. Dodge will then top that. Then Ford will come back and top that next year. One always out does the other. I just want a truck that will stay on the road for a long time. My cousin has a 07 Ford F-150 and he's had to rebuild the tranny at 54k. He had to get all new bearings on all wheels at 60k. The thing is falling apart. Hopefully my Dodge will out due that as they have in the past.
