backhalfing a toyota

what would be better to use 2x3 or 2x4

Either one will work just fine.

i would use 2x3 but like seth said either would work

id use 2x3. belive it or not i was told it is stronger than 2x4 idk if it true but it make sence

and its really up to what look your going 4

2x3 on a 1/4 ton is fine. I'd say minimum 3/16" wall.

yeah that makes all sorts of sense....

2x3 .083 is what we make our pro street chassis out of. but for what your doin, at least .120 wall, maybe even .250 wall will be just fine.

.08 would work fine, if the frame was going to have a cage attached to it. Otherwise I would steer clear of material that thin.

Unless you plan on towing with the truck, .120 will be fine. Though the problem isn't so much with the material thickness, but the stress at the welded joints. Make sure that you chamfer all of the seams and weld the frame up good and solid. Paying special attention to the areas that will have extra stress placed on them (ie. bag mounts, bed mounts, shock mounts.) If there is any concern, you can always weld diamonds over the welds to reinforce them.

here is one im RE-doning for a guy 2x3 3/16 wall (still alot to be done to the truck)
