Official Back-Half Thread!

[JAP]

Who's done it, who has pictures, and did you use a pre-built kit or build your own?


I doubt this thread will get much traffic, but I bet once some info is posted, it will get people thinking.

The guys I know have done it are Gene, and David, and that's it. I think Gene did Mike's and that's all of the SuperDuty's I know of. Anyone with any truck building experience with this type of thing, please post up!

Heeey yoouu guuyyyss...

 

[BullsEye]

[JAP]

Cut off the back of their truck.

 

[Powerstroked162]

Gene built Deranged as well

 

[JAP]

What about you? Are you just doing a regular cut/weld?

 

[Jomax]

You mean cut the whole bed and frame and make it shorter? For like offroading?

No, to make a RCSB instead of a RCLB.

Actually backhalfing a vehicle refers to choping the rear section of the original frame and replacing it with custom frame rails and suspension. It is usually done to allow lowering the vehicle lower than the factory frame would allow and put a custom suspension setup (usually a triangulated 4 link or 3 link with trac bar). And it could be done keeping the longbed.

Saw that build in person. Now I understand. Crazy stuff. Really. He wants to go lower

 

[ColtonP]

Nevermind. I should've read the whole thread before posting.

 

[BWCbuilt]

I am in the process of back-halfing my obs..... I am pretty certain that I have my cantilever four-link all engineered out, just gotta start burning some steel. watch my build thread for updates

 

[JAP]

Back-half kits can be had for around $1500 for the frame rails and suspension. I'm not really interested in a frame notch or a full custom build as much as I am interested in how the back half kit was welded in and set up.

 

[02BigD]

Ummmm...you work for David, can't you just call or email him?

 

[Hotrodtractor]

I helped install a back half on an S10 once. Measure about a dozen times, cut, pray, measure a dozen more times, weld, measure a dozen more times, race.

Seriously - find a common datum that is going to stay on the truck - find the center-line - weld in some reinforcing bracing - make your cuts - align the new frame rails with all the previous measurements - tack it in, measure everything, weld it in, measure everything. Link setup is a whole lot of info that would take a while to compile and explain in a post.

FWIW - I'm in the rough planning phases right now for doing one - probably be next spring/summer by the time I am to that point.

Here is my truck. Gene did all the fab when mike d. owned it.

Depends, honestly. If the truck does something decent with bars and good shocks, then no. If it acts like a homo on the street and at the track, I'll take it to Utah and let Moose 4 link/mini-tub it. David will be the first to tell you that ladder bars take the quess work out of racing lol. I will also admit that i don't know enough about the geometry and math to go along with a properly setup 4 link to do it myself and it isn't cheap to pay a chassis shop to do it. So if I can do without, I will lol
