I was wanting to know how much flex a cc/sb 4x4 could take. I know with my jeep I can get 2 tires of the ground but that is half the weight and a whole lot shorter in length. I don't plan on getting my truck in that situation but was curious as to how much these frames can take? I do drive back roads when hunting and wanted to make sure I knew my trucks limits.

mine flexes about four to five inches on either side (cab in relation to the front of the bed. these frames are super strong to haul big loads, i dont think you need to worry too much about frame flex hurting anything

I was wanting to know how much flex a cc/sb 4x4 could take. I know with my jeep I can get 2 tires of the ground but that is half the weight and a whole lot shorter in length. I don't plan on getting my truck in that situation but was curious as to how much these frames can take? I do drive back roads when hunting and wanted to make sure I knew my trucks limits.

Every truck has different limits and it's hard to know where they lie. Different body/cab configurations, tight/loose body lines, actual suspension flex vs not flexing, even tire and wheel combos, etc. all come into play. I've seen them flex like chevy1925 mentioned and have no issues. I've seen others that broke suspension parts(leafs,coils, shocks,etc.), crumpled body panels(done it:mad:), cracked windshields(done that too:rolleyes:), cracked frames, etc. Go out to a nice ditch on a country road(or an RTI ramp if you have access), and slowly drive in it at a 45 degree angle. Get out and check the area Chevy1925 mentioned(where cab/bed meet). The more you drive into the ditch the more you should see these two distances grow or shrink(depending what side you are looking at). This is how much your frame is flexing. Depending on the above factors, it may be a little or a lot of frame flex. You must be the judge as to whether it could be a problem. I've had it where the frame flexed enough to push the bed into the cab and create a nice dent, so drive in slowly(not far) and check it before going farther.:D (actually it would be nice to have a friend on the outside to holler at you if you get close).

Here's a pic to help show what to look for. The truck has the bed flexing up in relation to the cab. (actually not too good of a pic) You can also see that the frame is flexing enough that it's making the gap at the tailgate change. Notice how the gap is narrow where is says LTZ and gets wider as you go up to the bed rail; frame flex.

You can also see in this pic that the bumper is being pulled down on the driver side and pushed up on the passenger. Notice the big gap under the driver's headlight and the not so large one on the passenger side.(I think the bumper is actually hitting/pushing up on the pass. headlight and fender:eek: I had to drop my bumper(widen lines) to avoid this.) Even under the grill, the gap goes from wide to narrow as you move from the driver to pass. sides; fram flex again. All things considered, it's not too bad considering how large(heavy and long) the truck is and how much he has it flexed out. Hope this helps a little.(if it sounds confusing, I was trying to get out the door, so I was typing fast...Friday!:D)
