    Help understanding dual battery setup

    Bumping this thread back up again as I recently picked up this Stinger 200A battery isolator and just want to verify I am going to install this correctly. Based on the included wiring diagram and everything I've read online, I think this is how I should install it: Does this look correct...

    OBS Chevy/GMC on NBS Wheels

    GM #5299 wheels and Cooper Discoverer 285/70/R17 tires from a 2012 Silverado on my '99 Sierra: No rubbing, no crank on torsion bar needed.

    Control arms!

    I looked forever for lower arms when I redid the front end on my K1500! If I recall correctly, I read on some other forum that the only manufacturer of lower 4x4 arms for GMT400s stopped producing them a while ago. Don't quote me on that though.. I ended up just replacing the ball joint and...

    OBS Chevy/GMC on NBS Wheels

    I'm digging the look of NBS wheels on OBS trucks. Would these 285/70/R17 take off tires and rims from a newer Silverado fit on my '99 K1500? I'm currently rolling the stock rims with 265/75/R16s.

    5.7 rebuild questions

    I recently had a rebuilt 4L60E installed at a local shop so as long as I'm dropping money what sort of damage am I looking at to get either the original 5.7 in my '99 K1500 rebuilt, or have a rebuilt 5.7 installed? The engine runs great at the moment no trouble codes and is very reliable, I'm...

    Wheel well liners

    Yeah I'd like some too, but everything I found is NBS.

    Wheel well liners

    Thanks! I forgot about LMC truck. These are exactly what I need. Good thing they're only $16! I dropped off the truck this morning for a 4L60E rebuild... :mad:

    Wheel well liners

    I'm looking for some wheel well liners for the front (and rear, if available). They original crappy fiberboard liners or whatever they are made of are completely destroyed on my '99. Everything I'm finding online for wheel well liners is for GMT800s and newer, however. Does anyone have any...

    Scanner install

    No legal issues with this setup in AZ. I like the "close call" feature found in Uniden scanners - when a strong signal is detected within a close range, it will automatically tune to that frequency. There is also a daily VHF fire conditions forecast broadcast from the state forestry dept that...

    Scanner install

    I recently sold my Nissan Frontier and bought a 99 GMC K1500. I kept the Uniden BC355N scanner I had in the Frontier and flush mounted it in the empty factory CD player slot. Nothing fancy in this setup, but it's the perfect radio to monitor VHF/UHF comms when I'm out on forest roads...

    Help understanding dual battery setup

    Thanks for all the replies and helping me figure this out. Most likely this previous owner added the second at the time the winch was installed. Both batteries are connected from the positive terminals to the same point on the fuse relay center box, here's a pic: I don't see any battery...

    Help understanding dual battery setup

    When I purchased my '99 Sierra, it was equipped with a dual battery setup. I'm assuming the previous owner did this when the winch was installed. I've also read here that a dual battery setupo could be ordered from the factory as well. I'm trying to understand how this all works but I'm a bit...

    Parts list for my front end rebuild

    It turned out well - the steering is tight and it feels like new. I had a friend from work come over on a Saturday to help me and we were able to get through the upper control arms & ball joints, the steering linkage, pitman arm, and idler arm. Ran out of time, that took us a full day. I also...

    Parts list for my front end rebuild

    It's payday so the parts are bought! I should be able to get this done in the next few weekends and I'll update this thread with some pics. I couldn't seem to find any lower control arm/ball joint assemblies for my '99, so I'm going to keep the original lowers and just replace the bushing and...

    Parts list for my front end rebuild

    Another quick question - I've noticed that it is hard to turn the wheel when not moving or at very low speed. Is this steering box related? I'm wondering if replacing all the parts I've listed will solve this. I've also seen some other posts that also suggest the power steering pump may be...

    Parts list for my front end rebuild

    Thanks for the reply. The center link is cheap so I'm just gonna replace the whole steering linkage. I was hoping to avoid replacing the steering box as that is quite pricey. I don't see any leaks from it, but I'll keep that in mind. I found this relevant post, so maybe I'll just keep the...

    Parts list for my front end rebuild

    The steering is super sloppy in my '99 K1500 so I'm planning on doing a front end rebuild. This is my first time tackling a project like this so I want to make sure I've got everything I need. I've searched though some good posts on GMT400.com and watched a few how-to videos so I think I've...

    What is this part?

    Thanks! Looks like a quick fix, I'll bolt it back on today.

    What is this part?

    I'm posting this in Engine Performance + Maintenance because "if it's under the hood it's in here..." I recently bought a '99 Sierra and somehow hadn't yet noticed this seemingly stray part under the hood until today: Close up: It was just kinda dangling there, right above the steering...

    The Stupid Lift Questions Thread

    I have an early '99 Sierra GMT400, should I purchase the 95-98 Silverado/Sierra body lift kit from Zone off road? I'm wondering if the 99-00 kit is meant for the GMT800 as I'm pretty sure there aren't any '99 Silverado GMT400s. 95-98 kit...

    Sold my '11 Frontier and picked up a '99 GMC Sierra K1500 this weekend: I found this on a used GMC lot, single owner AZ truck (zero rust) with 110k miles on the clock. Clean interior. This will be my DD as well as my camping & fishing machine. First on the list are new headlight lenses, a...
