Not realizing that there are 3 different angles available for pork chops I ordered one for the right side from Jim K and got rid of the slop in the TB area and help greatly with the right side heigth. Found a used one for the left with little wear in the TB area and it took out the slop but the ride heigth dropped, worse than the right side was originally.I've checked up in the A arms while it was apart and little wear up there maybe because of the grease fitting mod years ago by a PO, Jim K said that was probably done by a company out west. I'm guessing it was a diferent angle pork chop. So between the 23, 25.5, and 28 degree which is the greater mechanical advantage and gives more twist on the bar as far as increasing ride heigth. Thanks.

Skip,
Here's a sketch of the pork chop, showing how to measure the set angle. As
shown at the top, where the 16* and 22.5* angles are shown, an increase in
the angle should give an increase in ride height.
(I should note that the pork chop from which I made that sketch was
probably from a Toronado. Also, it was rather presumptuous of me to record
22.5* for what was probably a 23* PC -- but it is what I measured. I don't
even remember now how I pretended to achieve such precision. :-)
I presume you do know that JimK now has SuperMaxx adjustable pork chops
that DO fit the GMC.

This is not commonly held knowledge but, the adjustable pork chop that Jim
K. sells is a work of art. I have held it in my hand and the fit and finish
is very good. It works as one would expect it to. Very well. Because of
slight differences in production fit in various OEM frames, suspension tab
location, torsion bar socket in lower control arm, etc. The factory had 3
different angles on the pork chop. None exceeded 1/2 of a HEXAGON which
would be 30 degrees. I work on front suspension systems on GMCs a good
deal. I use a simple check to verify that the torsion bars are still as the
factory built them. When the torsion bar is out of the coach, I place them
on two "V" blocks on a level surface, one near each end of the bars. Place
a digital level on one flat surface of the Hex on either end of the bar,
and rotate the bar until the digital level reads "0". Then place the
digital level on the other end of the torsion bar. If it is still as the
factory made it, it should read nearly level as well. This is an assumption
on my part, because I have never seen one that was not twisted due to age
and use. If the hex is out only a few degrees, they can be used as is. If
they are twisted more than 20 degrees or so, an adjustable pork chop is in
your future. There is now being manufactured a 4th option, although I have
not tried it yet. It is a laser cut replacement porkchop, made from plate
material, that has the hex hole rotated 30 degrees. If this won't correct
your ride height, I don't have anything else to suggest but to replace the
torsion bar. JWIK.

Jim,
I had some porkchops laser cut with 35 degrees. I sold half of them at
Casa de Fruta's flee market for $30.00ea
Haven't heard from anyone so I'm assuming it was just for inventory?

Wouldn't the fact that a porkchop with a higher angle indicate that ones torsion bars are losing their tension and probably are due for replacement?
I once had a spare set of torsion bars but sold them about 10 years ago thinking that I probably would not need them.
I still don't need them but am wondering if torsion bars are available for those that are losing their tension?

The 1-Ton torsion bars, which are available in a wide variety of strengths,
spanning our likely needs, are about 4" shorter than the GMC's, and have
larger hex ends. During my problem with the blown out socket on my 1-Ton
front end, I had several conversations with the owner/inventor of the
SuspensionMaxx adjustable pork chops. One of the results of those
discussions was that he designed and prototyped a simple adapter to fit
those torsion bars to the GMC. Whether he ever had anyone install one, or
made more than the one item, I don't know. But I do know where I'll start
if I ever have to replace one of my TB's.

Manny, I knew that it was you that had the 35 degree pork chops, but I
wasn't sure you wanted the attention that my announcement would probably
produce, That is why I didn't say who made them. But, since you have
said.......
To Ken Henderson, probably we will eventually wind up using all the one ton
components for the GMC's. They are a near enough fit, that it shouldn't be
too much of a stretch to use them. Good to have bars of various strengths
available, too.

Here is more information from the posting that I made back in 2006.
The diagram that is posted on GMCmhphotos.com is acccurate.
This just has a little more information:
> The three angles that GMC used on the motorhome were 23 degrees
> (part number 413683), 25.5 degrees (part number 418352) and 28
> degrees (part number 416373).
>
> Tto measure the angle, lay the pork chop in its installed
> orientation with the tail to the right. Draw a horizontal line from
> under the tip of the tail through the center of the hexagonal hole.
> Draw a perpendicular line through the center of the hexagonal hole.
> Finally, draw another line from the first hex point to the left of
> the perpendicular hole through the center of the hexagonal hole.
> The angle between that line and the perpendicular line is the
> measured angle.
>
> Since all pork chops were made from the same steel casting, there
> was no part number molded on them. The supplier put the part number
> on a paper label that is long gone from most of them. However, GMC
> used color coding on the side from six to nine o'clock. The 28
> degree one had a daub of yellow paint in this area; the 25.5 degree
> one had a daub of white paint; and the 23 degree had no color coding.
>
> If you can find the color coding then you don't have to go through
> the above measuring process. If there is no color you either have a
> 23 degree one or the paint daubs have worked or weathered off.
>
> The ones out of an older Olds Toronado will work. They have a
> bushing in the torsion bar opening to make it smaller. You can just
> knock out the bushing and the GMC torsion bar will fit just fine. I
