Bigdogtrucker Posted April 6, 2009 Share Posted April 6, 2009 I'm very happy with B-67 i just picked up so far.I bought it with the intensions of making a dump truck out of it(that i need).The major problem is,there's only 8ft of useable frame behind the cab!If i weld on 1ft on the rear of the frame,and don't move the rear back would that be a bad idea???I know it would look weird.Would i be better getting a longer truck???I'm not sure what to do.Any help would be great.

If you do decide to lengthen the wheelbase, don't cut the frame in the middle!!!!!The proper way is to add additional rail to the rear of the frame, then move the drive axle/rear suspension rearward to the required wheelbase.

de37champ Posted April 6, 2009 Share Posted April 6, 2009 the easy jobs always turn into a major job, i seen a fool that used 4 3/8 s bolts on each side to add 2 ft on his frame, it didn,t work out to good, the bed landed ride beside of me Quote Link to comment https://www.bigmacktrucks.com/topic/8920-dump-body-troubles/#findComment-33246 Share on other sites More sharing options...

Bollweevil Posted April 6, 2009 Share Posted April 6, 2009 What is the distance from the back of the cab to the center line of the drive axle? Depending on the length of the spreader lip, and what your intended use of the truck is 8 ft of frame might be enough for an 9 ft. bed Quote Link to comment https://www.bigmacktrucks.com/topic/8920-dump-body-troubles/#findComment-33257 Share on other sites More sharing options...

Bigdogtrucker Posted April 7, 2009 Author Share Posted April 7, 2009 (edited) I measured from about 1.5/2in.'s back from the cab,i have about 8.5ft of frame.Would it be safe to weld on 6-8in.'s of frame and NOT move the rear end back?Also,would 2 inches from the cab be to close for a dump body?Thanks Edited April 7, 2009 by Bigdogtrucker Quote Link to comment https://www.bigmacktrucks.com/topic/8920-dump-body-troubles/#findComment-33366 Share on other sites More sharing options...

It's been awhile since I spec'd a dump. IIRC, you need about 78"-80" for a 9' bed, and about 82"-84" for a 10' bed. I don't think adding on to the back of your frame is going to help. You don't want the bed extending too far beyond your rear axle. Steering will be "squirrelly" at best. Your best bet would be to check with a local body upfitter about CA requirements for the bed length your looking for.
