Cab Mount Chop - Food for thought?

How do you know? Looks? A feeling?

 

Y’know, this thread has been more interesting than I thought it would be. I didn’t know much about the subject to begin with, I was just thinking through my concern with this common mod and seeing what others had to say. As it stands now, I think there are several interesting things that have become apparent (to me).

1: There are safety concerns that need to be considered in altering this part of the frame, regarding some types of frontal collisions.

2: I perceive some paranoia from the post-CMC crowd, in what I consider some over-compensation in defence of the ‘good old CMC’. I would totally understand wanting to dispell some worry that my CMC’d truck was now unsafe for me or my passengers, or concern that my truck will lose resale value if this modification issue becomes more widely known to buyers, or fear of legal liability after a crash. Understandable!

3: There is a possibility that the CMC could be done to a higher standard of engineering so it does not compromise the design (gussets on the backside, correct steel and welding procedures etc). Maybe there is a business opportunity for a vendor?

4: Toyota is not just screwing us all with the design of the cab mount to prevent larger tires. They put as much space in there as they needed to for stock tire size and a set of chains, but the close proximity of the cab-mount to the tire is purposeful and related to safety. We are lucky we can “one up” to 31’s without a chop.

Anyways. Thank you everyone who added to this. I’ve learned a lot. Hope it wasn’t a total waste of time.

 

There are 4-5 kickers coming off the 6 foot slider ( which would also block the tire from entering the cab) similar to the picture posted of how ram is doing it.

The slider is roughly 6 feet long, 4-5 kickers, mounted by plates running across the frame and bolted or welded to the frame.

Also I just have a warm fuzzy feeling about it.

 

Good for you!
Look, I ride mountain bikes, even at my age I go hard. There is absolutely nothing safe about riding mountain bikes on singletrack! In the past six years I have broken a shoulder, foot, three ribs and two fingers. I have cracked two helmets. Near as I can figure this is pretty much average. We have maybe 20 guys around here who ride at an advanced level and somebody always has a cast or a brace or stiches something.
But.... the only person I can hurt is myself. Sure, I religiously check my bike components, torques, brakes and tires and check frame and shocks for damage. No matter what though I can only hurt myself.
When I change something other people (family especially) ride in or change functionality, it's a lot different to me. Now, instead of just hurting myself, my decisions could hurt someone else. And that decision I take seriously. So to me, I try to make sure I keep it as safe as possible when others can be impacted by my decision. That's just me and everyone is different.

 

Ha! I’m also an avid mountain biker, at my “advanced” age. Yes.....that is a different risk assessment.

 

What makes it different though? I ride for fun, exercise and adrenaline. To me it's all about just "me" getting hurt versus my passengers or fellow travelers getting hurt because of my decision.

 

I was agreeing with you. Not sure if that came across.

 

I asked someone earlier, but I'll ask again for better visibility. Does getting a CMC void the vehicle warranty?

 

Good question. I had a dealer tell me a suspension lift even if it's a drop bracket will NOT void the warranty but they do void boldly lifts. I think every dealer will be different

 

Well, I bought my truck in a different town that I live in, so i guess I'll ask the local dealer I get my regular warranty service if a CMC would void the warranty. I figured I'd ask people here who would know.

 

No, unless the cab dropped or something. Your mod must be related to the warranty claim in order for there to be a problem. For example, you can't have a warranty claim denied on your seat back just because you changed gear ratios. However, if you have a wheel bearing fail prematurely and you have put high offset wheels and heavy tires on it, then they could deny your wheel bearing claim.

 

Understood. Thanks. I was wondering if a CMC would be a broad warranty violation since your altering a structural portion of the vehicle, but I suppose that's open to interpretation.

 

As an example, if the Mass Air Sensor failed in your truck there is no way they could deny your warranty. However if the failure was something that was directly caused by the CMC they could.

 

It’ll void the warranty if frame rust is determined to start from where you did the welding on the frame.

 

Anytime mod.... hmm that’s a fun discussion. I’ll use the search or google, But hey OP I’m sure everyone here would love if you knew how to use the search function on the website or you know maybe google instead of creating a thread in the 3rd gen section wasting people’s time.

Cab mount chop has been happening on Toyota’s since 2005, I’m sure if it was a significant issue it would have popped up by now.

Like I said before. Do it or don’t it’s your choice and most people understand that most modifications done on a vehicle can change the safety.

But hey you keep on trucking, just use a search before you post. You look like less of an idiot then

 

Hm. I've read most of his posts and he definitely does not look like an idiot.
I think this thread covered a lot of ground currently not covered in previous CMC threads. Actually, if you take the time to read this thread you will see that this frame is quite unlike the 2nd gen frames.

 

That’s a dick post. It’s easy to be a douche on here but I guess following your statement if you don’t like it quit reading it. I don’t agree with everything I have read on here but still write respectful posts

 

@hiPSI

It’s more this had been discussed and rediscussed and rediscussed since 2005. It’s the same damn thing. It possibly affects the safety if you chop and plate. But it’s your own choice to do it or not.

That’s what is annoying, and he should have been able to figure out from a quick google search.

The cab mount does more then just protect the cab from the tire going into it in an accident right? Quite possibly maybe the 3rd gen cab is heavier then the 2nd gen so Toyota engineers made a beeefier mount to handle the weight?

I dunno.

But cabmount chop is a choice for the person doing it

 

Guess you missed his little hit on the anytime mod didn’t you

 

Perhaps, i read alot of stuff on here last night i can’t say I absorbed it all. Perhaps it is something that had been hashed out in a third gen thread where I am normally not. I just get tired of the “use the search button” comments which doesn’t work worth a shit anyway.
