66rmack Posted October 21, 2016 Share Posted October 21, 2016 So we have the superliner and we plan on stretching the wheel base and we bought a cut off that ended up being the wrong frame dimension. But I found a 88 superliner in the junk yard they want $18 a foot for frame rail. So I guess my ? Is is it worth it to buy the cab back so I only put one cut in the frame. Or is it not a big deal to have two splices? I like the idea of getting from the cab back cause our truck needs a trunion but I am looking for other people's experiance.

terry Posted October 22, 2016 Share Posted October 22, 2016 Is your existing frame good? If so add what you want to back of frame and unbolt trunnion and slide back, I don't know how much you are adding, but this way alot of the time you can have your weld in the trunnion bolt area, helps reinforce the weld area. terry 1 Quote Link to comment Share on other sites More sharing options...
br549 Posted October 22, 2016 Share Posted October 22, 2016 Like Terry said, we always cut the old frame and add on to the new frame in the middle of the trunnion so it had weld plus 4 drilled body bolts on the old and new frame, It will never give any future problem.

66rmack Posted October 22, 2016 Author Share Posted October 22, 2016 The frame is solid but there is a crack on the flange so I wanted to cut it there. 60" is what we want to add to it. Quote Link to comment Share on other sites More sharing options...
Timmyb Posted October 22, 2016 Share Posted October 22, 2016 I've pulled my ass end apart and yeah mine has been extended at some stage. As the rest have said, it was joined between the trunnion bolts and had some frame inserts added. As for the crack in the flange, I hope it turns out to be an easy fix. Would be a lot easier to fix that and add on the end. Quote Link to comment Share on other sites More sharing options...

I can move the trunion to the back that will give me a 210-215" wheelbase not exactly what we're looking for but it would def be better than it is right now. Maybe that's what we will do.

BAD DOG Posted October 23, 2016 Share Posted October 23, 2016 Anytime I've done them I usually try to do them the way Terry said its just a way neater and eat way to hide you'd splice and its a better reinforcement that cutting the truck in half .

66rmack Posted October 24, 2016 Author Share Posted October 24, 2016 Thanks everyone for your insights I think I am going to lead by your example. It seams like a no brainier to me. I wish it would be a bit longer but with the splice right there I'll never have to worry about the splice. Quote Link to comment Share on other sites More sharing options...
Timmyb Posted October 24, 2016 Share Posted October 24, 2016 I'll get measurements of mine today. I think you could get the 60 inches you want, or near enough to it by doing it as suggested above. Quote Link to comment Share on other sites More sharing options...
Timmyb Posted October 24, 2016 Share Posted October 24, 2016 From the chalk line to back of chassis is about 120cm. About 50 inches. 2 Quote Link to comment Share on other sites More sharing options...

Somebody cut the end of the truck off already andi can get about 28" if I slide it back to the end of the frame. Quote Link to comment Share on other sites More sharing options...
