The ultimate in neutral sway bars for the heaviest D bodies still available are the 1 3/8" QA 1 front and Hotchkis 1 3/8" rear bars. Other rear bars from Hellwig and a chrome moly from QA 1 have more roll resistance than the Hotchkis even though its smaller. The QA 1 can be paired with the BMR 1 1/2" solid rear bar on a Fleetwood and you'll barely notice the oversteer potential until you drive it like a maniac. The Nolathane REV 003.0182 is a front solid 1 3/8". Sadly no 1 3/8" solid rear bar.

FWIW These will not fit on any wagon. GM has a brace OEM that interferes with the DMR brace.
Don't think it was ever a clearance issue with a factory wagon gussets
Wood Gas Chair Machine Metal


More a length issue as the lower arm mounts are further apart than sedan while the upper spacing remains the same.

That is the Pro-Touring F-Body front frame brace .
It is not part of the suspension like the sway bars. It is a oem brain fart missing piece of the frame, sometimes called the chassis. OEM weak front frame rails BAD. Welded in brace for strong front frame rails GOOD.
The group purchase here long ago means lots of old timers already have this. The young? Probably not.

No
That is a B body with a boxed C channel. Point I was (attempting to) making was that the whole frame is weak. Yes the front (and rear) frame braces help a lot, but the only real fix for how weak the frame is requires welding. Today, I'll amend that slightly by saying that welding small gusetts into the C channel every 9-12" works just as well and does not require the body be lifted to do it, nor cutting holes to access the body bushings. Just cut steel 1/8" thick to fit into the C channel and weld them in. C is instantly very strong.
Confused, then, on the relation to aftermarket front sway bars.

My point was that aftermarket sway bars bend the weak frame unless the frame is made much stronger. Buy a new QA1 1 3/8" front sway bar (the most roll resitant you can buy today) and unless you make the attachment points on the frame connected to a much more rigid frame, you just bought the = of a 1 1/4" front sway bar. Find an old discontinued 1 3/8" solid or 1 1/2" solid, they will bend an OEM frame even more.

I guess this is what was confusing me. But I get your point now.

When it comes to the LT1, or the 4L60E, much if not all of the ISSF is eager to improve on what GM left unaddressed.

When it comes to the frame, much of the ISSF is hesitant to improve on what GM left unaddressed, which means one never gets quite what they should from suspension upgrades.
About as succinct as I can put it.

I got a new mig welder over a year ago, but finishing the garage has kept me from playing with it. Along with some things planned for my tractors after learning and practicing welding, I also plan on sticking in a collection of the frame channel gussets as frequently discussed. It's been reported they are relatively easy to weld in for max. effectiveness using locations not requiring large-scale undercarriage disassembly. A rough graphic of the locations along the frame-rails along with an equally rough description of the gussets would be as much appreciated as it will be helpful for portraying to others how accessible and 'accomplishable' the mod is. Realizing of course many who contemplate the work would need the confidence in knowing they can farm the work out to a mom-n-pop shop or muffler chain with acceptably low risk of components or lines or 'xyz' getting damaged.

It's almost impossible to do it wrong.
My wife would earnestly posit the inverse. And does. Perpetually. About everything.

Seriously,
I take it just 1/8" mild plate,
-a dozen thus total pcs.,
-most anywhere insertible along the length. = Thanks.

For clarity in positioning, are you welding these pieces inside the C channel (face of the steel plate side to side with the car) or along the outside of it (face of the plate front to back of the car)? I'm trying to understand which direction of frame deflection is being reinforced.
