All you truck owners, how much does your bed flex?

    I have noticed that between the cab and the bed at full flex, they are missaligned about 5 inches causing the bed box to get all twisted. It doesn't seem to hurt anything, but is this much flex normal on a un-reinforced frame? the /forums/images/graemlins/truck.gif is a 73' K10 short bed for clarification.

    thoughts? opinions?

    Thanks. /forums/images/graemlins/smile.gif

    Well, about 2 weekends back, i was out playing on this bank near our road and I took a hard line; the results of which were my tailgate getting rejected with force. /forums/images/graemlins/whistling.gif (roops) So that's gone now. As far as how much my bed and cab were off, you'd have to ask my buddies who were watching. I assume it was bad.

    They all flex quite a bit. Years ago I had a brand new F-150 short bed pickup that flexed so much that the bed made dents in the back of the cab. /forums/images/graemlins/eek.gif

    My truck has about 4" of flex between the cab and bed. I want to make sliders that mount to the body, bridge under the tank with a heavy plate, then go up to the frame. But I don't know if this will limit my travel or make the ride uncomfortable. I like the way twistedjack's looks, how'd he do it?? /forums/images/graemlins/truck.gif

    My bed moves way too much. It has beat the fire out of the back of my cab and every time I get really twisted up, especially if it twists hard one way and then back the other way I get "go go gadget toobox" where it makes my toolbox lid pop open. I will have the frame boxed within the next 2 months and that problem will be solved.

    Sounds like it's time for new body mounts. I highly recommend them. I'm willing to bet it'll solve your problem.

    My truck isn't very flexy in the front even with 4" BDS springs but I have very limited frame flex. The body mounts (GM OE) are not quite two years old yet. The box diamonds a little bit when the tailgate is off but I still can open and close it. Keep in mind that my box has seen 20 years of rustbelt abuse and the cross supports look like swiss cheese. The front frame does twist a little bit in comparison to the core support.

    For good measure, I have my box moved as far back as it'll go on the slots in the frame. I can fit my hand between the box and cab.

    However, if you've got bad body mounts and tinker with your springs a bit like GMCLegacy did a couple-three years ago it's easy to get some wicked body flex.

    Even moderately bad body mounts are better than horribly wasted ones.

    The simple solution is to get rid of the bed entirely.
