C4 Ladder fitment off, gouged out area behind tabs

Nothing to do with C4 really, but the HD struts are acting strange to me. I live at 5,000 ft, I was at 12,000-8,400 ft last week and they couldn’t lift the tailgate at all. A sealed system, doesn’t make sense. Though this has been a mountain topic for years. Strange, working now back at home.

Did you have the window down the second time?

Lol...maybe....

I just went outside and tested. I likely did have the window down several times, and yes it will not lift fully but makes a good effort, maybe not making that last 20%. But at altitude it had next to zero lift window up or down. No biggie, just not making sense. Glad it is working now back at home.

Several comments on the trip about how cool the C4 ladder is.

I installed the C4 ladder recently. At first I thought the struts were weakening, but then I realized whenever I had the window down the struts would have a difficult time with all that weight out on the end.

With the window up, my gate will hold itself open at any position. I have to help it up a bit, but it can hold the weight.
 
Any updates on the C4 ladder? I ran this summer with a roof top tent, and was climbing up on the roof a lot to tie down the tent and ladder.

I like the looks of the Gobi too, different than the C4 but I love the C4 products. Currently running it as a skid plate and I've been quite tempted by their rear bumper.

Just wondering if that top plate issue has been resolved.
 
Just Installed this myself today. Was incredibly easy. Put it together in my basement while watching the first XFL game and enjoying 2 brews from Treehouse.

Put it on the truck myself and was super easy. I know they recommend 2 people, but was very easy with just me even after 2- 8% brews.

Everything fit absolutely perfect. Its a much better looking ladder than I thought it would be. I had wanted the Gobi, but the whole order process was a PITA.

I ordered in Mid Jan and had the ladder 2 weeks later. Its dark here now in Boston area, so no great pics, but so far gotta say I really like it.

No Problem opening with my Frontrunner full rack. We will see with RTT..
 
2020 June ladder install summary:

received my ladder last week (so i assume i have the most up to date of what's being shipped out)

just finished installing this ladder on my 2020 venture edition to gain easier access to the basket it comes with, and it was a pain in the dick! i followed the youtube instructions verbatim and triple checked my measurements. What i ended up having to do what just undo the carriage bolts and pinhead bolts holding the top step and top plate to the ladder. i installed the top plate first and put a few bricks to apply pressure to the adhesive for a hot minute.

(I noticed also without the ladder hanging off of it, the top plate wasn't sitting flat at the 3in. mark. I adjusted it side to side before sticking it down and it still just wouldn't sit flush and flat against the the roof, so i left it at 3in' per instructions)

I then attached the ladder to where the bottom hovered over the appropriate holes on the bottom bracket that wraps around to the inside of the hatch. I then installed the 4th top step and bolts back VERY loosely.. LOOSER than my high school ex. I then installed the carriage bolts to attach the bottom of the ladder to the bracket below and tightened it all up.

LASTLY, i pulled the ladder straight out back with some help then finally torqued down the top pair carriage bolts and 4 pinhead bolts up top. This part was a P A I N I N T H E D I C K, but at least the top plate sat "somewhat" flush to the roof. Way better than what the instructions told me to do. I stood on it and pulled/pushed and seemed it was secure.

I then took it to a local fireroad that's got quite a bump to it with whoops and doohickeys and hauled ass with the newly installed ladder no weight or extra accessories on it. I didn't hear any obvious ladder related rattling, but after I got out to see how the ladder was holding i was starting to see slight lift at the hooks despite me installing it "HELLA FLUSH" and DPing it with BBC level cardboards to show who is boss.

I tried to see if I could do any adjustments while on the field (Damn, I'm hardcore.) but just like women the ****in' ladder doesnt know what it wants to do.

Overall the ladder is killer and will leave it on, but **** me am I probably gonna get annoyed everytime I see that top bracket slowly clawing at the inside of my snat- i mean hatch door.

I DEMAND A FREE ROTOPAX L BRACKET AND AN ADDITIONAL STEP FOR MY EMOTIONAL HARDSHIPS WHILE INSTALLING THIS PRODUCT. DAMN YOU C4!!! *SHAKES FIST IN NO APPARENT DIRECTION*

j/k ily. product is p cool. i'll rock it.

PS: I'll post pics later.

I am still a bit pissed too. It still scratches after they send me 2nd plate. Some tried to shave the edge of their plate.

Me too! Still scratches and I'm on the 2nd plate. Love the damn ladder but not how I've installed it twice and it's still scratching my paint off.
 
anyone recently order this without issues?

i just had to return my victory ladder because it was causing the same issue and the only solution they had to was to return it or adjust the hatch out another inch to accommodate
 
My wife ordered the C4 ladder for me at the end of November, it arrived earlier this week. I installed it today with no issues on my 2020 TRDP. I read through the PDF instructions on the C4 site, watched the C4 install video, and also read through the install guide on Trail4Runner.com. The C4 install video says to measure 9.25" for the bottom bracket measurement, the Trail4Runner site said 9.5", I went closer to 9.25". I did a couple test fits before removing the top bracket adhesive covering. I stuck with what the C4 video said about how to initially place the top bracket (pretty much centered so that the washer covers the entire hole. I was a little concerned that the top bracket wouldn't sit flat, but I thought after tightening down the bottom bolts that it would sit flat, and it did. Seems like a solid product, it doesn't move at all when climbing it or pulling on it.
 
I installed mine approx 6 months ago on a 2012 4Runner, and I remember 1) sticking in as much carboard as possible between the roof and the mounting plate, 2) placed weights on top of the plate (with carboard in between), and 3)leaving it there for 2-3 days so that the adhesive can work and keep the plate hinge as close to the rear as possible. It works great now. Nice and horizontally leveled. Great product!

I have a 19 4runner pro and I installed the C4 Fab tonight. Followed the instructions online, and then watched the video. Once installed, I test opened the hatch and it dug deep into the paint on both tabs. No amount of adjustment on the top or the bottom would fix the issue. I then attempted to grind the tabs down slightly to add some clearance. No luck. I am beyond frustrated that my brand new truck now some deep gouges in it.

Anyone run into this issue, or am I all alone?

Same thing happened to me. Got a nice gouge on that inner surface thats hard to access. Did you do anything to fix that area? Any paint or anything that will help prevent any corrosion?

This was 2 years ago and I do have the C4 ladder on my car as well but DAM! My ladder does not sit that high with the double sided tape. I'm wondering did they give you the wrong double sided tape/did you use the wrong one? The one I got was thin and my ladder sits nice up top. maybe after 2 years, they decided that the thicker double sided tape you have on yours was not cutting it.

Did you try test-fitting the ladder before installing it? The top-plate is at an angle atop the adhesive, which is causing it to rub against the body. That isn't the normal position after installation. With the top-plate flush, it shouldn't contact the hatch at all.

Sorry to see this on your rig.
