    Can I use the “better 2011” hydroboost?

    I can confirm it fit my 2001 Suburban 2500. It was a direct bolt on, I didnt have to mod anything. It does seem to provide easier (less effort braking). I also replaced the power steering pump with a Duramax version from PSC- Also a direct bolt on (with yer old pumps mounting hardware). While I...

    2003 Yukon XL 2500 - Rear Heat Coolant Leak - How To Fix

    Nice work, thanks for writing this up. I wonder if that Dorman part number is actually intended the front heater core connection? Makes sense gm would use the same part for efficiency’s sake. I just replaced all the quick connects and coolant hoses in the engine bay with Metal Dorman “upgraded”...

    Sunroof Dead

    Mine’s a 2001. There is definitely a “manual ” calibration procedure that involves holding the sunroof button as you turn the key on. I suspect there is another fail safe ecm lockout that only dealers with a fancy scan tool can access but i dont know fer sure. mines dead dead- even jumping the...

    Sunroof Dead

    I had my pristine (original owner) 2500 burb parked and covered with a tarp for years when my sunroof stuck open after a battery change. I spent hours researching, jumping the switch connector in the over head console, tried the “key on hold button ” reset procedures many times etc I just gave...

    Do torsion bars wear out?

    The z85 in the VIN decoder is described as “chassis increased capacity” the Z82 is the trailer hitch/wiring. Also says it has the 9900lb brakes which i noticed some of the rock auto parts descriptions for this truck mentioned as an option. Anyway, it looks like i need 6gk and 7gk torsion bars...

    Do torsion bars wear out?

    When i backed out the tosion adjusting bolt, the keeper key was already loose. I didnt hardly need the unloader tool as just a couple turns by hand on the tool gave me clearance to remove the keeper. Also, it appears the bar might have a slight bend to it. All the gm parts places say the part...

    Rooftop tents?

    To answer my own question, yea they do. It says 200lbs if anyone else wonders. Rooftop tent may not be a good idea for my weight.

    Rooftop tents?

    I wonder if the owner’s manual has roof rack capacity somewhere. GM engineere almost certainly spec’d a load capacity.

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Two uber cheap upgrades from junkyard on my 2001 sub: 1. I installed 2nd batery tray from a duramax equipped truck and another starting/backup battery-bolt on easy peasy. 2. I snagged two factory roof rack crossbars and added them to my rack for additional support.

    Rooftop tents?

    Will the factory rack on a 2001 support a rooftop tent? The manufacturer specs say “Vehicle mounting cross bars must have a dynamic weight load of at least 165 lbs.” I added 2 factory (junkyard) crossbars as a cheap reinforcement for a basket which seems more stable, but i just dont know if a...

    Headers on 2001 2500

    Looking at headers on Ebay, there are some nice looking stainless headers that say they'll fit on a 2001 Silverado, Denali, 1500, 2500 etc but says it won't fit on my 2001 Sub 2500 with 6.0. Aren't Silverados and Suburbans virtually identical from the drivers seat forward?? Also wondering if...
