G-Max box sway bar

[tbear853]

The normal tow pack bar is probably the 13/16", but the police bar I mentioned is 1".

Not on any PI I ever had. I had '98, '00, and '06 when I retired. We are talking rear sway bars.

box rear bars were larger, but they also mount and operate in a different way than bars on round cars so they may need to be fatter for the same effect. Not an engineer, so I don't know the fine points of it but box rear bars bolt to the middle of the lower control arm on the 4 link suspension only. Round cars have a pair of brackets with rubber bushings on the axle that the bar passes through, and the ends are fixed to the frame with links.

OK, I guess was the mention of ADDCO 650 put me in mind of Whales. I see now that y'all are talking about a bar bolts to splayed out lower control arms like was on my old Chevelle. My bad.

Hopes dashed again. This tang is turning out the be a deal breaker, they can only do a 4" flat with their current tooling. The flange on our bars is 135mm long (5.250ish)

In theory, we could drill one hole and use the other factory hole and it would work with a four inch tang?

I'm not a customer since I'm lucky enough to have of the originals. I also have the smaller bar on the other car. The difference is substantial in terms of handling.

I got in touch with PST suspension on the phone and talked in depth about the G-Max bar.
The gentleman I spoke with was a 50 year experienced body and fender guy that has a thing for the Panthers too.
This is what G-Max said.

Manufacturers reply:

"Well that depends on a few things Dan.

If he's welding or drilling in the center or "torsional" part of the bar, I would recommend neither.
If it's the arm of the bar he might be OK. Depends on diameter of the bar and size of the drill.
Welding should be OK on the arm of the bar but he needs pretty good penetration so I'd crank that welder up.
If it's a pretty good diameter bar (maybe 1.0 or up) the weld is not likely to hold regardless of penetration.
None of these actions are really recommended but he might get away with it.
I'd say he's got a 50/50 chance."

I'll be looking into this a little bit further with a friend that has a welding business for 40 years. He'll know.
