The kits nowadays are plug and play for almost any factory bulb type. The only thing you need is some double sided tape to mount the slim ballasts. Most of the issues with aftermarket HID has been with crummy light dispersion when plugged into a non-projector housing. Fortunately the Sierra comes with projectors stock!

Don't forget you need the harness to fit the Sierra so the computer doesn't shut the lights off. It's like $9 from ddm...

One other question: I read that only hi beams work on this truck and that low beams are controller by a shutter. This is evident by the distinct line drawn where the low beams end. But this line is so close to the vehicle that traveling down unlit roads at night is kinda scary on low beams. Is there any way to adjust the height of this shutter to shoot the low beams a little further?

Philips screwdriver adjustment, very easy to do. Google it for photos and videos showing exactly where to find it.

Just having projectors doesn't automatically mean the vehicle is good to go for HIDs. The reflector inside is still different. And I still hear of occasional issues even from the "big" brands of HID junk with failing ballasts that you may have to wait weeks to arrive from China for.

Off subject a little.. but related.. does anyone know where to purchase a LOW/HIGH beam kit.... so the low beams stay on when you turn on the hi beams?

 

I had this kit on my old silverado... and that's the ticket! really helped. I can deal with the factory low beams around town.. but out in the woods.. I would like everything to stay on.

on the Sierra this won't be possible because there is only one bulb being used (shared) by both the high and the low.

Looking to put something along the lines of silverstar ultra's in my '14 sierra. I don't see anything listed on sylvania's website. I thought I saw in the HID thread that 9006 bulbs would fit, would that work for the silverstars also?

 

Thanks,

Halogen 9006 will fit, though some brands might require a slight alteration to do so. Nothing major.. at most just snipping a piece off the plastic tab with finger nail clippers.

 

I believe the zXe's are currently Sylvanias "whitest" bulb.

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.

Are they any improvement to stock? Can you post a link to the bulb

As far as the other comment above, ultimately it's up to you if it's worth it or not. No 9006 is going to put out as much light as a 9012. No 9012 (currently available) is going to give you any "whiter" light than the stock bulbs.

So your saying the HIR bulbs that come in the truck are brighter than the Halogen bulbs on the market now?

 

Not really looking for a 'white' look just more lumens, especially when I put the brights on.

Geektoad was correct about the bulb's output:

 

9006 - 55 watts - 1000 lumens

9005 - 65 watts - 1700 lumens

9012 - 55 watts - 1870 lumens

9011 - 65 watts - 2350 lumens

 

Commonly, vehicles use 9006 for low & 9005 for high. Unfortunately, the Sierra's have "bi-xenon" lamps which basically means the 9012 bulb is always on, always putting out the same amount of light. For lows, a little shutter blocks some of it (especially above the top of hood) and when you hit the highs, the shutter moves, and you get light cast in additional places... but the lumens never change. It sucks! Headlights are the one area I'm really jealous of the Silverado's (they have separate bulbs for highs)

 

For this reason, you'll see many on this forum switching to HIDs or adding LED light bars.

Thanks for the info Motomedic Maybe I'll take a closer look at your HID thread and see if I want to put in the effort to switch! I didn't realize the silverado had better functioning head lamps.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
