^^ Frame bending...nice. Certainly didn't make you happy. Definitely is decision time. How much is it going to run to straighten it, any idea?

Looks like it's not the kind of bend you can straighten. New frame is $4700 plus labor and all the other bits and pieces. Not sure if the bed mounts are good still.

Sorry to hear you bent your frame Rob. I assume you were part of the recent group trip. Where did the frame bend?

I haven't seen your truck/frame but I have to believe the frame can be fixed and I'd guess it could be done for less than the cost of a new frame and labor to install it.

I know a Raptor owner who bent his frame above the rear wheels where the frame is thinner by design (probably designed to crumple in a rear-ender).

If the frame isn't fixable(I don't understand why it wouldn't be) cut it off at the cab and link the rear. Now would be the best time to do it. The $4500 that it would cost to fix would buy lots of parts when you linking the rear.

So you get a lot more travel with a 4 link?
With a 3 or 4 linked rear end you can expect 28-32 inch's of rear travel.

Exactly what I was thinking (cutting it at the cab). The shops I talked to, though, recommended caging the cab too, so they can build the rear end off of that. They said without the bed, 30" of travel with a 20" shock was pretty reasonable. With the bed, they think 26" travel with an 18" shock.

Most places are quoting around 4k to tube the bed. The price goes up if I want to change shock mounting locations, and that doesn't include the new hardware (shocks, springs, fuel cell, etc...)

How far down this rabbit hole do I go?? And then, what's the point of 30" of rear travel when I've only got 12" up front... seems like the truck would be unbalanced. If I'm going to build a truck up, I might as well buy a wreck and go from there...

Oh, another thought. Most shops I talked to recommended a 3-link. They said the 4-link added more cost than was necessary for my purposes. They said the 4-link offered a little bit of redundancyl; you could limp back to pits if one link broke. AII, you have any thoughts on 3 vs. 4-link?

4K, that's not to bad at all, you have to think about how many hours go into building a truck at 55-65$ an hour plus materials, most big shops are in the 15-20K range. Who did you get a quote from?
Always cage the cab if your going to play hard in the dezert. And especially if your going to link the truck.
I'm kinda curious on the shock mounting location comment! No matter what the shock mounts have to be built cause you wont be using the stock mounts.
I've driven many trucks that have 12/13 up front and 28/30 inch's of travel in the rear and it does work pretty well cause the front tends to bounce over the whoops while the rear sucks them up. The rear tends to buck more than the front causing you to go end over end, this is why setting the rear up is more important.
.
This truck only has 13 up front and 28 in the rear and it loved 3-4 foot whoops

Building up a truck from scratch is NOT any cheaper, trust me, I should have bought a Raptor and slowly built it::::wanna trade :) :::::

EDIT: 3-4 link doesn't really matter on a full size, 3 link is just fine as this will save you on heims, but in all honesty, whats a few hundred dollars. 4 link offers the option to limp back depending on what else it broke, if designed right you will never break an upper link.
