tubular a-arms
 

Will tubular a-arms made for Impala fit c3 corvette?
I've read at quite some sites that it will with no problem.
I found Summit has them at very nice price.

What are the benefits of installing these arms?

Lower weight, more rigidity and if you buy adjustable, adjustability.

Taken from 63-67 corvette restoration book!

I have no personal first hand knowledge of this interchange other than knowing the C2/C3 suspension design did come from the late 50's Impala. A quick Google search found this...

"same stamping with different sway-bar brackets, the bottom ones are switched side-to-side and wind up shaped backwards with the concave-curve to the front instead of rear."

So sounds like they fit other than possible swaybar end links?

I did a search in this forum and found a thread from 2006 that said "need to weld a tab or stud to mount the swaybar link"

so, if you are comfortable with a welder you can save a lot off the Corvette-tax for the lowers. The uppers fit as-is but they do not have any additional caster built in so I would use a Corvette specific model for the uppers.

Found this on NCRS of all places:

The spindles (steering knuckles)used for 1963-64 Corvettes were the same part number as those used for 1959-64 passenger car.

The upper control arms used for 1963-82 Corvettes were the same part numbers as those used for 1958-64 passenger cars.

The lower control arms used for the 63-64 Corvette were of different part numbers than those used for 1958-64 passenger car. They may work ok, but they were of different part numbers.

The upper control arm shaft for 1963-82 Corvettes was the same part number as 1965-69 passenger car.

The lower control arm shaft for 1963-82 Corvettes was the same part number as 1958-69 passenger cars.

The steering arms for 1963-64 Corvettes were unique to 1963-67 Corvettes and were not used on any passenger cars.

Friend is a professional welder! :D

Did anyone notice these new control arms:

I picked up a set of upper and lowers for the 58 -63 impala shipped for under 300.00
they are 15 miles from my house so I picked them up total saved the shipping but had to pay tax. And yes you have to cut off the sway bar link bracket and weld it on the back side.

Do you have to change sides right to left or just the sway bar links have to be swapped?

Those look like some nice pieces, thanks for posting. T :thumbs:

watching

Yes side to side thats why the sway bar link brackets has to be changed, what was on the front is now on the back.
I was going to build my own but not for 300.00

With free shipping here are the same but diff seller.

I was looking at one of those!
Can you post some pics when done or when doing the conversion?
Also how did you measure the correct place to weld the sway bar mounts?

I haven't put them on yet. I'm collecting and building parts plus I am using a straight sway bar with rod end links. Measure off the old one.

That I kinda doubt. Stock a-arms are pretty dam strong.

I thought the same thing, but then came across a set of tubulars for a good price and threw them on. I was absolutely floored with how big an improvement it made. Hands down the best handling improvement I have made to the car to date, and I've done a bunch of steering/suspension mods. If I was to do only one handling upgrade it would be to put tubular control arms on the car. The stockers are made of wet noodles in comparison, seriously
