Evan said it was about an 1.5 in too short, but that told Tom add more just in case so maybe he will do it 3 in. Per Tom, the beds should not even be close to touching about 1in apart. I would contact Jay. So far they are making me happy.



Just a thought here - your experience and mine seems to be that the frame is ~1-1/2” short and that the shortage is somewhere under the cab area. This pulls the bed forward into the cab space (and in my case it was a tight fit to get the cab on the mounts as it was squeezed in there). I’m interested in knowing where the shortage is exactly.

I have mine set back just enough to get ~1/2” space to the cab because I drilled new holes for the front bed mounts ~3/4” back . I set my running boards on yesterday and they are a pretty snug fit between the front and rear fenders but there’s enough flex in the fenders that they fit. If I had another 3/4” they’d be great but the bed rear mounts would be nearly off the rear frame. I also need to crawl under it and see if the running board mounts on the chassis and boards line up?

If TCI is going to add in anything more than the missing 1-1/2” you mentioned they suggested 3”) then you’re going to be messed up in the other direction. The running boards will end up hanging in space and won’t reach both fenders and you may have a really big space between the cab and bed.

I’d make sure they have a good plan to get this correct including mocking it all up to get it to fit right. Adding in an arbitrary amount just to be sure could leave you with another mess. Best approach would really be to build a new chassis which meets the specs and swap it out for you.
