FASS Titanium 95GPH lift pump for 15-16 Duramax. Bought for my 2016 Duramax but ended up selling the truck before I installed. All original parts included. Box was only opened to verify everything was there after purchase. T o be clear, as the box says, there's no warranty on the product if you don't buy it from an authorized dealer. They go for $700-750 new. $500 OBO. Local sale only, No shipping. Cash sale only, not looking for trades.

The tow mirrors don't have the auto-dim feature, and I miss it.

Max Tire size on a Stock Height 2015 2500HD
geektoad replied to bigsby's topic in 2015-2019 Silverado HD & Sierra HD
I'm running a suspension maxx level kit on mine. It's not fully level, because I wanted to my angles in decent shape and i also didn't want to be nose up when towing/hauling. I've seen quite a few others say they run 305s without a level though. I've probably dropped in mpg, but I'm all over the place in what i do with the truck...short trips, highway, towing, hauling, etc. so it's hard to really have a good feel on mileage. It's also only got 6800 miles on it, so it's not even fully broken in yet, so mileage will still improve a bit over time. -
A lot of dealerships are refusing to install them afterward because of the high likelihood of leaks from the lights when they are installed after the fact. My dealership gets every HD they order for stock in with the marker lights because so many people ask about getting them after the fact and they don't want to do it.

Max Tire size on a Stock Height 2015 2500HD
geektoad replied to bigsby's topic in 2015-2019 Silverado HD & Sierra HD
The stock 20s are 8.5" wide. 295/55r20s will be just fine on them. I, and many other people are running 305/55r20s on them with no problems. -

7000lb travel trailer with 2015 Suburban
geektoad replied to bearcat77's topic in Trailers, Hitches, & Towing
You'll be fine driving unloaded. 90% of folks that spread the negative info about diesels have never driven one. I just did the same thing as you're contemplating. Had a 1500 sierra, bought a 7k dry/10k gvwr toy hauler, and decided to jump into a duramax denali. It's awesome, i've had it for about a month and have no complaints (except for the crap stock "rancho" shocks, which i dumped for bilstein 5100s). -
2014+ Gas Mileage (MPG) Topic
geektoad replied to BringTheRain403's topic in 2014-2019 Engine, Driveline, & Exhaust
You can indeed over inflate tires, but the max inflation for truck rated tires is generally 44psi or higher. Running at 38-39 will not harm them. -
2014+ Intakes (CAI) & Air Filters
geektoad replied to GMC-AT's topic in 2014-2019 Engine, Driveline, & Exhaust
Can't speak for anyone else with the 5.3, But I'm waiting for the Airaid Jr. for our trucks. No point in replacing the stock box, as it's already sealed off from the engine bay. -
Halogen & LED Headlight Bulb Upgrades
geektoad replied to Ezekiel2517's topic in 2014-2018 Silverado & Sierra Mods
If you replace your stock HIR bulbs with regular halogen bulbs, you'll be going from about 1800 lumens to about 1000 lumens of output. I don't care if it's whiter light, there's no way it's worth cutting your light output by nearly half. -
It has definitely been a while
