Mounts to the frame the way all the rock slider / running boards / side steps do. Four attachment points on each side, two bolts for each attachment point.

 

2nd gen ZR2 sliders mounted to the body with some support/triangulation brackets.

And with a lot of 2nd gen steps compatible with 3rd gen, my guess is body mounted.

Mine are body mounted and I've lifted the side of the truck many times with my hilift and have seen no damage or misalignment after years of use

 

My understanding is the 2nd gen rails/steps bolt right to 3rd gen.

Factory rails for a Gen 2 bolt to body, specifically the rockers.

So…. My guess is 3rd gen also bolts to rocker, not the frame.

Sorry Saturday Morning Dyslexia - strike frame insert body.

 

Yep, I can confirm that the 3rd Gen rocker protectors attach to the body, not the frame.

 

Yep, I can confirm that the 3rd Gen rocker protectors attach to the body, not the frame, sadly.

It's a pretty solid mounting design though, for being cab mounted.

Weld on universal sliders are also available.

 

I know ideally they would be mounted to the frame, and it's been a point of contention for some... but has anyone had an issue. I know I put a lot of weight on my Gen 2 rock sliders and they didn't budge. They guided the truck right out of whatever the predicament was. Just from the look and feel the third gen seem quite a bit stouter?

 

Cheap sliders from china maybe.

The cab is ridiculously strong. It has to survive an SUV impact to the side.

Smacking some rocks at low speed is nothing.

 

Yep agreed, these are plenty strong.

 

My 17 has some moderate hits on the sliders, nothing really hard and I use my hi-lift to jack it up with the slider. Very solid design. A few small dents and scratches on the bottoms.

 

The GM sliders are pretty expensive not including the removable steps. I was trying to find out if every 2023 Canyon was universal as to fit, particularly to the Denali. But the dealer had no idea. The GM parts for MyGM rewards has no idea either. They say they can't confirm with GM factory because of the strike. Common sense would say they should fit. GM shooting themselves in the foot if they don't - JMO. But glad to hear the rest of you think they are strong. For the expense, they should be. Was also thinking about these which are a little less than the GM product;

Anyone with a ZR2 or person who bought these afterwards from chevy able to confirm if these are frame or body mounted? I cant find installation instructions online and have not been able to track down a zr2 underbody photo to inspect. From the description, my gut tells me they are body mounted. I am trying to determine if these will be good for use as actual rock sliders or wait to get something aftermarket that truly is frame mounted for the additional strength a frame mounted slider provides.

Those are rocker mounts, no hybrid solution at this time. I will say the way they mount is OKAY if your not rock crawling, basic offroading they are very sturdy and won't pinch the seam unless your slamming them on rocks.

 

I'm going to weld mine to the frame. I think they would survive a few light rock impacts just fine. Most of the overlanding crowd doesnt need anything heavier. But a few frame tie ins aren't going to hurt anything. They feel like they are .090 wall, a little thin. But the shape is nice.

 

I see this is an old post…did you end up tying them in before the Rubicon?

 

Old thread but I got a quick question as I’m looking around at people selling their Colorado ZR2 / Canyon AT4x OEM sliders.
can someone please confirm if 23 AT4x OEM sliders willFit my 24 Trail Boss?
And what would be a fair price for used ones that have are a bit scratched up but not dented
thanks

 

They will fit no issue.

I wouldn’t pay more than $300 for them especially if they’re scratched…and even that I’d say is on the high side. I’ve had 4-5 different ones saved on facebook marketplace for months in Denver (a few have been off 2nd gens but are almost the same as the 3rd gen and fit interchangeably) All of them have been sub $250.

 

I have 2nd Gen sliders on my 2024 Canyon. I paid $100 for them. They were in very good condition,

 

Hey guys. New question. Found a local guy that has gen3 sliders in good condition. But he doesn’t have mounting hardware (he didn’t remove them, dealer did)
Can anyone please tell me what hardware /bolts / sizes are needed and it’s an easy to source generic parts so i can either take or pass on his deal.
thanks

Not to keep bringing this thread up. But have one more question if anyone with Gen3 can confirm?
Does Gen3 uses the same mounting brackets as Gen2 for support? Or is gen3 sliders only mounted via 4 points (2screps each/8scrws
Per each slider side).
im
Finding people selling gen3 take offs but none of them have brackets that gen2 come with. So I’m confused if they are mounted differently?
Picture from under frame of gen 3 slider would be super helpful
Thanms

Side by side comparison of Gen 2 to Gen 3. Gen 2 uses reinforcement brackets not included in the above picture. Gen 3 include brackets welded to rails.
Identical mounting location of 8 bolts (2 per mount).
Mounting hardware for GEN 2 can be found via part number 84141179. Identical hardware minus the brackets are used on GEN 3.

If you would like to piece together hardware:
95210A200 No-Slip Clip-On Barrel Nut, Black-Phosphate Steel, M8 x 1.25 mm, 0.8-4.5 mm Panel, Packs of 25
95211A180 316 Stainless Steel Oversized Washer, Passivated, for M8 Screw Size, 8.4 mm ID, 24 mm OD, Packs of 10

I found the barrel nuts to not be particularly corrosive resistant.

 

On the gen3 slider bolts they need to be torqued to 21 foot pounds. Easiest way to install is on one side, put the 8 clips in. Partially screw in the 2 farthest bolts(front and rear) that go in horizontally then hang the slider. I then inserted and snugged up the 4 bolts that go in vertically. Install and snug up the last 2 horizontal bolts and torque all of them down. Did it by myself in less than an hour...

 

well i also just got done with mine, timing worked out that a set came up for sale locally (new take offs).
install was actually fairly easy by myself, funny enough i just saw STONE111 msg and that's the order i did mine in as well.
**21 ft-lb ?? thank you, i thought it was 18 like on Gen 2, so will go back and re-torque them up to 21.
before / after pics:

 

Actually I called the parts dept. at my chevy dealer and he told me 30-40ftlbs. thats way to much as i almost stripped one bolt out. I played with the torque on a few more bolts and 21 seemed to be the sweet spot. If your confident with the 18 just call it a day. If there is a space between the bracket face and body then maybe go up a few pounds to get the brackets flush...

 

 

For the guys concerned about the fact that it "technically" mounts to the body, I assure you it is an extremely solid 8 point mounting system that allows it to take some serious abuse. The points where the brackets mount to is very reinforced and its a well engineered design... Not to mention the sliders themselves are very heavy duty and have got to weigh about 60lbs. each, maybe more. I vaguely remember reading a blurb saying that they are made of stainless steel but cannot confirm that.

 

The sliders themselves are fine enough. But body mount will never compare to frame mounted sliders. @Mr Stig can attest that they will kiss the body at one point or another.

EDIT: 99% of people will never use their sliders enough for it to be a concern. I do acknowledge that.

 

If someone is going to constantly bounce their truck off off large rocks then yes, go with frame mounted sliders. I kind of figured that was common knowledge without stating the obvious.

 

I guess I don’t know why anyone would put them on at all if they don’t plan to smack them into rocks.

 

The torque spec is almost certainly 18 lb ft.

Agree with the sentiment, these are not ideal for "off-roading". At best these provide a little door ding protection, hide the pinch welds, and give an aesthetic with the black plastic arches. Not to mention a place for steps to be added.

 

They are some if the better factory sliders I've seen. You can lift the truck with them slowly. But all it takes is one small drop off a rock from a front tire and bam, they bent into the body. Before spring I'll make some proper DOM sliders similar to stock look. If people want them I could make some more. So little aftermarket for these its sad. And most of the aftermarket is catering to looks. not performance.

 

If you make them let us know. I'd certainly be interested.

 

I do like the factory ones but if you wheel hard, frame mounted is the way to go.

It's just that many people don't want to go down that rabbit hole. Once you weld on the frame, warranty is gone. And honestly, with how cheaply/thinner things are on these trucks, not sure bolting them around/to the frame is any stronger than mounting them to the body at multiple points ?

 

Hey guys, do the 3rd gen sliders provide a bit of a step to assist getting in? Or do they sit tight to the body?
I have several shorter family members that have to hop to get in. Id like to add some protection for off roading (nothing crazy, mainly fire-road sorta stuff), and make it a bit easier for them to get in and out.

Thanks in advance for your help

 

ITT would be a stretch to call them a step. I can try taking pic tomorrow but I can only get edge of my boot on them and they aren’t that much lower from door opening so don’t think of them as steps.
but I do believe with these oem sliders you can add steps to them

 

Light offroading, the factory ones are fine and most people don't know but you can order steps that bolt onto the factory rails, so you can actually use them to get into the vehicle. I believe that the front and rear are sold separately.

If you plan to be dragging the truck on the rails on a regular basis weekend after weekend you will be better served with rails that bolt to the frame in as many places as possible, preferably 4-5 places. And definitely not 2 or 3 unless they are substantial mounts.

People on this forum have also said that the 3rd Generation rock rails are a little bit more robust at the mounting point. Not the truck but the mounts on the rails.
