    anyone ever make a extension for their v-box. I read somewhere that a 12" extension would increase a 1.8 cu yard to 3.0 cu yard. Anyone ever do this and do you have any pics???

    A 12" extention would only increase capacity of an eight foot Vbox by 32 cubic feet (4'x8'x1') or 1/4 yard.

    I thought a yard was 27 cubic feet

    make sure your truck can handle the extra weight and theyre a good thing but it also must be secure becuase of the increased weight

    You're right, of course. I was thinking about a cord (of wood) being 128 cu ft. That's what I get for dealing with two different things on the same day.

    Actually more than that. But that's for another thread.

    I put 22 inch extensions on a highway super p 10 ft. The problems I had was not much but the shear pin would shear. I had an inverted V in the spreader also. The pressure on the drag chain was a lot more with all the salt above the chain. The truck was large enough to handle the extra weight.

    I mounted the grate on the extensions. I got a new spreader and will not put on as large of an extension this time.

    Since I have a 8 ft box, how high should I go. The truck will handle it thanks.

    I put 2x6 extensions on my 8' V box. It will hold 4500lbs of straight salt. The salter weights another 800lbs. I have this on a 2003 3500 gas GMC. The GVW is 11,400lbs and we come out of the scales within 200lbs of that and usually on the high side. The truck has a flat deck on the back that is 9' long and it has no sides so it isn't that heavy.

    I put 2x12 extensions on my 6' v-box. Couldn't afford an 8 footer at the time and with the 12" extensions I almost doubled my capacity. I drilled holes through the lip on the spreader and used 3" stainless steel lag bolts. Used 8 bolts on the 6' side and 5 bolts on the short side and two angle brackets in each corner, unit is very solid. Salter can easily handle 2500+ pounds of material. Usually don't fill it all the way, but it's nice to have the extra capacity when you need it. I have some pictures posted on another thread titled "my money maker'.

    i also planned on adding 24" extensions to my 10' BOSS salter. I never thought about the shear pin however....... maybe i will have to make that inverted V bigger to keep the weight off the chain. Right now it only runs the length of 8' so maybe i will run the full 10' and make it wider so the salt only has a 4" gap on both sides to meter through.

    Only one way to find out........

    here are my sides, 2x12's with 2x4's in the corner with a lot of deck plate screws, and 1 screw in each corner of the v-box, the wood sides sit on the lip on the inside of the v-box, no problems yet from the extra weight, had a custom truckers canvas made to keep things dry
