Hi guys. I own a 2019 Sierra AT4. My dilemma is the optional factory 'assist steps' (#84630474) I've seen on AT4's later than mine...mostly on 21's and above. Pretty sure I've seen them on a 2020 AT4 as well. Will they fit a '19? Everywhere I ask people tell me they're "pretty sure" they'll fit but I'd like to know for certain as most places offer no refund, so I'd be stuck with them. Some fitment charts say they won't fit. My guess is that they do, but weren't even an option until 2020 and kicking me a "won't fit" because of this. Much appreciation in advance.

I don't either. They are pretty sharp looking IMO I'm surprised nobody has tried this before. $1k  is hard to drop on a chance (however slight) they won't work. Thanks for the reply.

I have these on my Silverado and people ask me all the time where i got them from. I bought mine at a Chevy dealer and got the ones for the extended cab but I have a double cab so they exchanged them with no problems or questions asked. Buy them from a dealer and not mail order and you should have no problems if they don't fit.

Same generation, no changes to the underside, should bolt right up.

 

My wife and I like wide steps, we're getting old!

This guy got them for his 2020 which is also listed as not compatible.

No idea why they say not compatible unless it's because GM didn't bother to go back and bolt them on to older trucks. The cabs are the same for the T1's and all the threaded inserts are already in the cab floor. You just have to pop the plastic plugs off the ones you need to use and thread the bolts into them to bolt the brackets up. I wanted a set of those steps until I saw the price! I went with a $260 set that tuck up high but have drop down bars to protect the body. They're aluminum so they're light as well.

Thanks for the info guys. I think the collective thought in the thread is that there's no reason why they shouldn't. I will most likely get a set but be on the lookout to score some a little cheaper.

The only thing I thought of is if your truck is a diesel. I know the DEF tank is on the driver side and I saw something about different brackets for the diesel.

I was at the dealership this morning and there was one at4 on the lot with those wide steps and they look better than I thought on the truck not bad at al all, I might keep mine after all

Ok so if anyone reads this my question has been answered. They do fit. I have a pair on my 2019 Sierra AT4. Bolted up no problem.

I removed the wide style on my '20 AT4 and installed the factory "high clearance" steps posted above with no issue.  I picked them up for $300 locally removed from a brand new at4.

be the guinea pig man, 98%+ they will work and you'll sell em real easy if not as there's nothing better, I've now seen mine in snow, mud, combined frozen etc. and they are awesome, the grippy stuff and how solid these are, combined with their fitment to body and clearance makes them in a different league and worth the money imo, they happen to look incredible too, they aren't lightweight, I'd have to guess 25-30 lbs a side, quality stuff, best side step I've seen outside of some custom aluminum extruded grip strut type steps I've seen on oilfield trucks, anything works if there's no snow/mud etc. but most are slippery hazards in that stuff, these can play for real work, and don't forget they are there when jumping out, that grip stuff can give good road rash to the back of your calf, it's a self trainer and you learn the lesson just after you put them on 😉

 

also, there's multiple locations on the board for the 3 brackets to move to, to align with different trucks frame points etc., so they designed them to fit several trucks

Frame points? Do these actually bolt to the frame and not the underside of the cab?

    • You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode. 
    • "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
    • // Thank you, also for your  response. More information is always good. This 2013 GMC is most likely my 'forever truck"-I'm 77 and retired...and truck only has 42K on it-very clean-so I try to keep it that way.  Tks again for your  response- glenn
    • I started my install this weekend. Everything was pretty straight forward but I ran into one issue with running power through the firewall. The nipple grommet on my High Country already has a small harness running through it - has anyone else ran into this issue? And on the engine bay side, does the wire basically just penetrate the factory wiring boot? I did this on my '22 Trail Boss and it seems much easier but thats been a few years. My other thought would be possibly drilling a new hole adding a rubber grommet just to the lower left of the factory hole. Thoughts?   Has anyone used a T-harness off the Bose amp and obtained power from there? It seems a little odd that such a small amp needs 3 power leads
    • ///// Ok--Thanks for that info--I could not find yesterday when I looked for the specs on that NAPA filter what I wanted. Their website is not very user friendly. I buy all teh filters for  our three vehicles once or twice a year. Have always run NAPA Gold on everything I own....I buy it thru my Son's account for his business-which he has a Heavy Equipment repair shop-one reason he uses NAPA so much-they have such a full line of coverage for just about anything/anywhere- He gets s  good discount because of volume bought. Anyway-Thank you -Sir for your response.   glenn
