So i got a 3500-HD truck and it had no hitch so i looked around and didnt like what i saw in options / price point / availability. . . .

So i have a stock gm hitch off a 95 c1500 truck and i based my design off it and BEEFED it up just a bit . So taking a known working design saved me time .

So i got out to my steel pile and grabbed some 3.5x6x5/16 L-IRON for the side plates . Then 4x4x1/4 square tube for the main tube .

Next was a builder 2x2" hitch 12" long and 2 5/8" D-rings and a chunk of 1/4" plate for the plug mount . Then 8 1/2" grd-5 bolts and stover crimp locknuts and THICK BEEFY over sized washers to bolt it all to the truck frame .

I used my hand drill for the starter holes . Then hypertherm xp45 plasma cutter for the big work . Dressed them all down with the 4.5" hand grinder with a 40 grit flap wheel . Once all ready i bolted it all up to the frame and burned it together for good .

Then i pulled it for 100% weld out and paint . Gave it 2 coats of rustoleum black and let it dry over night . Then i bolted it up for good this morning under the truck .

Now to wire in the plug and swap on the new flatbed and get to working this old girl with her 8.1L vortec and nv4500 with 4.63 gears .

yaa i get accused all the time of overbuilding every thing :cheers:

rear ov these trucks frame rails are 34" outside to outside and the reg 1500-3500 is wider so they dont swap directly over . but i liked its simple yet beefy design so i just made one like it but bigger / stronger / 2 more bolts over the stock 6 like the rest all use .

I cut 2ft off the bed and pulled the icc bar yesterday . This let me use the hitch for towing the work trailer that when full is in the 10k lb weight category.

and i built the 12k lb max capacity sealer trailer from scratch my self over the winter . had to go threw a state dmv inspection to get a vin# .

Is the 8.1 throttle by wire in this truck?
It should be. I don't think any GMT400 was ever drive by wire (exception being the diesels?). But I'm pretty sure the later 8.1s in the 2500HDs (and perhaps 2500 SUVs as well) did get drive by wire (in the GMT-800 platform.)

Pretty sure all 8.1 motors were drive by wire in the 8XX platforms.
