Swapping electric running boards to stationary

[AOK]

Hi all. I have a 2021 Yukon XL Denali with automatic running boards. Wanting to switch to stationary (OEM or aftermarket) but am running in to a lot of issues since the automatics only have two mounting points. Nothing seems compatible. Does anyone have any solutions or ideas for swapping to stationary running boards? Thanks in advance, my local GM dealer and two off road companies in town have come up empty so far.

Appreciate that, unfortunately that is just a trim piece of the electric boards I believe.

Why can't you order one left and one right of (these appear to be the extended wheel base version), may need to look up for the short wheel base.

Left P/N	Right P/N	Description
84809518	84809519	Left and Right with Chrome Insert Fixed Running Board Assembly
84809514	84809515	Left and Right with Black Insert Fixed Running Board Assembly

Would think any body shop worth their salt could install these (or would think is not too tough to do yourself). Cannot imagine that there is a difference in the body/frame of our rigs whether or not they have power or regular boards on them. I'd thiink all mounting holes are there...and some are not used depending on which step you ahve installed.

The only challenge may be deprogramming the option in the computer as not installed...and not sure what happens if you just unplug them. Perhaps if you unplug the Control Module for the auto running boards, the vehicle will recognize them as not installed...not sure.

Note, @AOK, scroll down in the list that @Blackcar provided; the fixed version is listed on the same poage, further down. The assembly P/N's provided include the mounting brackets too.

Scroll further down link you will find bolt on.

It seems like it should work, I agree. But for some reason two shops, my GM part department and two different running board manufacturers have all said that they have a different attachment system with the auto-deployed boards.

They probably do but if you buy stationary boards they will come with attaching system that work with them.

For sure on the aftermarket...and, like I said, I gotta believe there are holes/threaded nuts welded to the frame in the correct spot for both the stationary and power -- there are not 2 frame P/N, no dang way. Has anybody put it on the lift and looked, or crawled up under to see? I would do it myself, but it is -10 here and I broke my leg...so I can't right now...

If the dealer can't figure it out; suggest going to a body shop...they work on these things all day...they will know.

If they are selling the ones in link in post #2 I linked and say they fit vehicle in search the attachments that boards come with will fit locations in inner rockers on truck for sure.

Any updates on this? Would like to do the same. More worried about programming and check engine light after they are unplugged.

I disconnected my running boards on 2017 premier, when they were in the extended position. Its one wiring hardness ( I think there is a second for lights ). It didn't trigger any error messages/service lights. I'd try that quick fix over buying anything.

Anyone know how many and what size bolts the 2021-2024 Tahoe Z71's running boards use to mount?

 

[AOK]

I ordered a pair of the running boards for a z71 Suburban. They went right in!

Thanks for the follow up post. Did you have to do anything to the vehicle after unplugging the powered boards. Maybe just turn them off in the radio?

I have a 2023 Yukon XL AT4 and had the driver side replaced under warranty and now need to have passenger side looked at with about 800 miles left on warranty. Planning ahead when one fails again. Thanks

I have no experience with these, but I wonder why you can't just extend these and modify wiring and/or switch so the boards stay extended.

Or extend them and clamp or weld the arms so the boards stay extended.

Or something...

There are no problems at all in replacing electric thresholds with stationary ones, you buy thresholds from the catalog, they fit into the regular places. The main problem is to properly isolate the power connectors from the electric thresholds. Because if you cut them, it will be impossible to return to electric ones. I installed stationary ones after I was exhausted by their work.
