I'm actually interested in knowing how I can go about it because I just can't force myself to pay for something that can be easily made.
OK, how I made my 3" body lift. (I'll add photo's later) lets get the basics first.
For the body (assuming an extended cab), you will need 6 "Riser" blocks (tubes).
What I did was a chunk of 3" schd 40 pipe cut to 2-3/4"" lengths.
I also used 6 pcs. of Heavy Wall Schd 80 3/4' (ID) as a center "Anti-crush".
12 1/8" thick 3-1/8" Diameter washer made with a rigid brand "hole saw" in a drill press. (home depot). and a mandrel for the hole saw.
3-1/8" ends up being 3" ID, Now here's the thing, this is the exact same OD as the large pipe's ID BUT don't forget about the anti-crush's.
So I lined up the anti-crush tubes centered on the mandrel's pilot hole, and welded them to one washer (to keep them from sliding to one side when the through-bolts go on.) I then flipped them over and laid them on top of the 3" pipe, since the anti-crush is inside, it acts like a support for the washer to weld it to the 3", then flip the entire thing over, and weld the other washer to the other side (the anti-crush is welded to only one washer).
What you should end up with are 6 units that look like a 3" tube with a plate on both ends, I then drilled out the original pilot hole with a 1/2" bit in the drill press (I used a large pipe wrench wedged against the back tube of the drill press to keep the 3" pipe "riser blocks" from spinning as I "Line-bored" the two end plates, (through the anti-crush center tubes).
Next, I used some 3" "C" channel for the box risers, simply making 4 (four) cross rails with 4 holes in each ( there are only 6 bolts in the box (3 sets of rails), BUT there is a "blind" rail in front of the rear axle, since I wanted to carry stuff in the box, I also made a cross bar for this one, but with only 2 holes, as to bolt it to each frame rail. The BACK pair of cross bars ALSO got a pair of joiners that went between them, creating a "box", this releives the stress load front to back when braking and starting off. I welded these in place after I had the cross bars lined up on the frame.
As far as the steering column goes, just above the steering box, there is a "slip joint" remove the cross bolt, and the two plate bolts, and the slip joint can be removed from the truck as to "slip it" in a vise with a bar and hammer. You should be able to get the full 3" out of it, but that would depend on the year of the truck, as a buddy when to do it, and his would only go 1" so we had to insert a splice in his slip joint to get the full 3" (actuall it's a bit more, because of the angle, so MEASURE it before you modify the slip joint.
Parking Brake, I had a chunk of flat bar (3/8" thick, 1-1/4" wide, and about 4" long.
The P brake (cab side) would NOT reach the original mount, (and I didn't want to try and strech it for fear of braking the casing on the cable), I simply drilled a pair of holes the right size and bolted the bar (pointing up) to the original cable mount on the side of the frame (grade 8 bolt, 2 washers and a lockwasher), just under the DR door. I then inserted the cable in the other hole, just as if it was the original mount, all of the rear portions of the P brake, are stock.
The Bumpers, I scabbed up a set of flat mounts that would raise the bumpers up to the new body height, you can see the frane-rail ends under the bumpers, but IMO, the bumpers look better beside the body, instead of "floating in space".
Fuel filler...... because it gets real cold where I live, I DID NOT want to try and stretch the top of the fuel tank (plastic) so currently my filler rides under the hole, loose, I take the cap off, and pop just the rim of the filler through the hole behind the door It's PITA, but will soon have the time to work on it. (will repost to this message, once it's done).
OOT (One Other Thing), the 3" c-channels at the back, I'm in the process of making a 2" receiver that mounts between the bottom of the bumper, and into the 3" c channels, again, I'll post here, as time to finish permits.
The bolts for the risers where grade 8, 1/2" there are two different sizes needed if I remember correctly the original rubber mounts are about 2-3/4" thick, add your risers between them and the original rubbers, bolts on cab where 7" long, bolts in rad support where 6" long (you will have to double check this). washers and lock washer AS WELL AS (nylon pem locking nuts)
The Bolts for the box, I re-used the original torx bolts and frame clips in the c-channel to box, this way the box still comes off, just like factory. for the c-channel to frame, I use grade 12 bolts (pretty sure they where 1/2" also, but can't remember), but only like 2" long, washers and lock washer, AS WELL AS (nylon pem locking nuts).
The box bolts, where coated with "Anti-Seize" for bolt removal at a later date.
