Put a set of half fenders on my international 9200 look good but I only now have 2" of clearance between the fenders and the tralier wondering about raising the 5th wheel plate up 2 or 3" any suggestions or pics of anyone who has done it before or is there any companys out there that makes spaces for something like this

you can order one... call north central international.... Not hard to put on. I had to do the same thing on a peterbilt when i put WTI fiberglass full fenders on. Or if your not far from Hutchinson... Call 320-587-9431... Ask for Jim... He can find you a used one as well if you know what 5th wheel plate you have, and sliding mechanism. They are just a welding shop but they do alot of frame stretching, and putting box and hoists on trucks, and sometimes the trucks they have come in will have a 5th wheel and riser on it. So they keep them and sell them.

We have done several of ours but I don't have any pics. If you have the style where there is angle iron bolted to the frame and then the plate sits flat on top of that we just get heavy wall reactangular tubing and put under the plate. If you have the style where the angle iron is part of the plate and bolts to the frame we just take the air arc and blow the welds off the legs and weld spacers under them to get the height we need, we usually use 2-3 inches. Hope this helps.

No need to buy them. Can be done cheaply and easily by following jd4930's method. Or atleast that is the way we have always done it.

Why not just get a set of taller legs for the plate? They usually come in 2-4 different heights.

Get taller legs it will look better than bolting more steel to the frame..............

It won't work because you didn't pay some tech skool dropout at a dealer to do it.  Don't you know that people like you and I can't do things like that.  Steel is a carefully injuneered substance.  Only specially trained idiots are allowed to drill holes.  It's a highly technikal process.

I agree on the Rect Tubing. And then maybe not. First, what was the country of origin, USA? The first time it was sent to China for scrap? If so then if it comes from China it is OK to use it. John Deere does it everyday. Next, get a Professional engineer to review your plans, get the plans stamped. Drill the holes. This may require using very precise measuring instruments, aluminum straight edge, center punch, and such. Drill one hole every 15 minutes so it doesn't over heat and stress the steel. After two weeks of drilling it needs to be painted, using DOT approved paint. Use caution when purchasing the bolts, they must be all from the same lot # from the manufacturer and keep a copy of the shear specs in the truck at all times. When torqueing the bolts, use three torque wrenches and several witnesses. Check, verify, re-check. Be shure to cap the ends of the tubing so road salt doesn't corrode them in 40 years.

At this point you may be inclined to haul only at night, holidays, and weekends while DOT is usually off duty. Possible get some small International decals and apply to the tubes so they look factory. If you follow these steps closely it propbably will work, but there is no guarantee that it won't fail.

We have been across scales like that several times before without issue., even in Illinois. It comes down to who stops you and if they need to write a ticket or not, then it doesn't matter if it is right or wrong.

The NAT codes that people from Illinoiz like to make up. Sort of like the guy who told me that the flat bed I fixed up the suspension on last year wouldn't pass DOT. Hmm...I welded it....and braced it. Better than the guy that originally installed it when it was new.

It's not just a matter of drilling holes, you also have to get longer bolts. Better call an engineer...

I have one that looks pretty much exactly like agboy's below, minus the fenders.

We just bought a fifth wheel that sits up higher. Might cost a little more but a whole lot easier than all that work. You just need the brackets it attaches to. Most over the road guys like the low profile so they fit under bridges with tall trailers, for farming the higher it sits the better.
