My GMC 2012 Sierra 2500 HD is listed as commercial on the registration certificate here in Ca.. I purchased it used several years ago & just noticed this. It's strictly private use. I pull my small 21 foot trailer to the coast once a year on vacation. Other than that I make trips to the grocery store, Dr. appointments etc. So I'm wondering if all trucks this size are considered a commercial vehicle in Ca.? Thanks ..read more

I have a 2008 Sierra that has a vibration. I had the drive shaft looked at and it is fine, as well as the u joints. The truck will run smooth then start to vibrate for about 35 to60 seconds. the vibration will start slightly and get progressively worse and the then smooth out. Then it will run smooth for a couple of minutes and start the same thing over again. The vibration seems to be coming from the rear of the truck. Any suggetions would be greatly appreciated.Rick ..read more

Looking to add air lift suspension 2020 Sierra 1500 Denali 4WD Adaptive Ride Control

I have been doing a lot of research and still have some confusion. Air lifts website they do not work with ARC. Etrailer.com Q&As that are conflicting. Some of them say some firestone air bag will work. It appears the active suspension 4611 and 4611-HD will work with ARC, however you have to deal with the rear being lifted 2 inches and harsh ride if you choose the HD. Not sure the non-HD would even help much. Another non air lift option would be the Hellwig 81912 helper springs. Was... Read more ..read more

Hi y'all, my dashboard "information center" went out a while back. It was out for around a week or so but came back on for a week maybe, then out again. It came back on again a month later but went out again for a month now. Everything goes out; all gauges, and the odometer/trip miles display. So, no speedometer/tach, gas guage, or trip miles. I can't know when I'll run out of gas, or tell what my speed is, both pretty important, lol. This is my second 1500, first was 2001 and this one is... Read more ..read more

I've got a stock 2014 GMC 1500 All Terrain Pkg/5.3 V8/ Loaded. Was questioning a higher than normal voltage reading at the factory volt gauge and my remote start fob would not work sometimes, and for one-time only....it would not crank to start with the ign key. Changed the battery in the key fob....same issues. Had the charging system checked, & was told that the Alternator was putting out HIGH voltage and that the battery was reading in a LOW state. My factory dash voltage gauge was... Read more ..read more
