2007 NBS part life expectancy

elite0259 · July 15, 2017

Hi everybody I have a 2007 NBS Silverado crew cab Z71 LTZ 5.3L with around 145000 miles on it. I'm going on a 500 mile (1 way) roughly 1k round trip to Maine this coming week as well as another trip of similar mileage in a month with a 7k lb total weight boat trailer.

I'm wondering if I'm in the range of failures that people have heard of. I know in the '99-'06 body styles from what I noticed the fuel pumps would go around 150k and the sensors would bite the dust around 130k.

My truck still runs like it's new and I'd like to not end up on a tow truck.

Parts are gonna fail when they fail. Hard to put a clock on them. Fuel pumps in the 800 series usually failed WAY before 150k. Change fluids/hoses/belt etc... and other parts when they go. Your AFM and trans are what I'd most be concerned about

What do you mean by NBS? You mention 2007 but no way can a 2007 be an NBS. The only NBS is current production. Unless you count the 2019 test mules. Now that becomes NBS.

It's model year 2007 with the 2008 body aka gmt900

Thx for the input txab, I didn't know if there was a 10k mile range that was predictable like the earlier generations

I would say just go for it. Have you properly maintained your truck? My tranny went out at 98k and I followed GM's service recommendations. Sometimes you just don't know when something is going to fail. Also you could have a brand new truck that would throw it's guts up.
