View Full Version : Front Axle: Ever tried using both early and late front anti-roll bars together?

Yes, it can work and is certainly CASO; (actually, CCASO, as he's Canadian, spent zero bucks getting a stiffer anti-roll setup ;>)

The later frame-mounted Stude front sway bar wasn't as stiff as he wanted and he didn't want to pay for the aftermarket vendor heavy duty front anti-roll bar, so BrandX end links end links for the outer ends of the late bar to the A-arm, reinstalled the early bar and both together does the job for him.

Not a Stude, but yes, I did.

Once upon a time, many years back, I built a hot rod 1961 Chevrolet Impala. A 421 inch 409, a full manual, switch-pitch, T-400 trans., down low to the ground, NASCAR (Basset, steel) wheels, big Goodyear radial tires, heavy springs front and rear, a large rear anti-sway bar.
And yes, the OEM 5/8" front anti-sway bar, along with a later model GM 1-1/4 dia. bar that fit around the original bar.

That car was a beast. For a bunch of cheap (cept for the engine) parts, that car ran and handled "WAY" better than it had the right to for a nearly 4000lb car.

I did the same on my 56J, and my 64 Daytona.

Perhaps it is late and I am just missing something

Could you walk me through what was done please. What I understand is later front V8 bar was not stiff enough and a second bar was used. Stock bar was left were it was and second bar (brand x) was added where?

As a variation on a theme, the six cylinder bar goes from A arm to A arm, could you install the frame brackets and modify the stock V8 bar or add a brand x bar? I still have a front bar from a 64 and brackets in the basement.

Somewhere I still have a rear brand x bar that bolts to the rear axle but that's another project.

Jeff, the earlier Studes anti-roll bar was clamped to the A-arms. Later, Stude made brackets which bolted to the frame to hold the center of the bar and only the outer ends clamped to the A-arms. The modification with the later bar using BrandX links moved the outer end attachments above the A-arm and an early bar was re-installed with the two clamps on each A-arm.

Ok, I get it. I'm more familar with the Lark era of Studebaker engineering. Gives me an excuse to buy the parts manuals prior to the Lark

Thanks.

And, I'd assume if you mounted the lesser bar tight and the greater bar somewhat loose you could get a "variable rate" anti-roll bar(s)?

OK, I'm CASO but I'd think just buying the thicker Camaro bar at a self pull yard for under $20 would accomplish the same and still not strip a man of his CASO image. I mean I get it that the guy was just tinkering around and it worked. But can a CASO be too CASO? :confused:

Like Mike in # 2, I too did it with mid 70's GM intermediate chassis rear bars mounted to lower control arms. I simply used longer bolts and added another bar underneath the existing one(they were about 3/4" diameter). This complimented the 1 1/2" Herb Adams front bars I used to use. I think for our Studes that wittsend has the right approach with the readily available big Camaro/TransAm front bars and cheap.

Sorry, no such thing as a "variable" anti-sway bar.
They are ether connected or not, working in full or not.

On the other hand, maybe with some work, one could use a small shock absorber as the link to the control arms.
BUT...that would not only defeat the purpose of the bar in the first place, it would take a bit of work, AND...most probably not be fully controllable.

Just as a "loose" anti-sway bar would be as inconsistent as the addition of a shock as a connection.
A properly working bar should start working as SOON as the body leans, otherwise, they don't do much good in controlling body roll.
