Quickor suspension has finished working on a new design sway bar set for the B-body. Using a street rod frame Impala with a 1 1/2 inch solid rear bar, the need for additional camber control and roll stiffness in the front, started the project.A 1 1/2 solid front sway provided perfect balance in the street rod but required a very uncommon level of chassis stiffness. Part of the problem is the front frame rails of the stock car bend when using a 1 1/2 inch solid bar, even though it solves all the problems B-body cars have with front roll stiffness insufficiency when a 1 1/2 inch solid rear bar is used.This problem persist even when radically different spring rates are used front and rear. By creatimg a front bar with fewer bends, a 1 3/8 solid front bar is made to perfectly balance a 1 3/8 rear solid bar. The front is stiffer than any other currently available front bar because of the reduced number of bends. Mounts straight across, below the idler arm, by use of an unique bracket system at the attachment points. Leaves room for the option of welding a frame brace between the front frame rails, though this is not required. The matching rear bar has the option of being mounted to the side of the LCA, which also makes for a slightly shorter, so slightly stiffer bar, as well as a bar which mounts in the traditional fashion. On a stock frame car the matching 1 3/8 front and rear solid bars effectively balance roll stiffness while maximizing camber control, while allowing for a variety of lowering/spring rate options.

Should have included this section in the first post- technical glitch on my part deleted it. The new design by Quickor is recommended in 1 1/4 inch solid front and rear for stock frame, OEM chassis cars. They feel that combined with various after market suspension components, the 1 1/4 bars will provide an optimally balanced starting point. These bars will also fit and are recommended for A-body cars. The 1 3/8 bars,[ and even 1 1/2 inch solids! ],are available for anyone who would be using very unusual combinations of custom springs and shocks and frame reinforcing. Glenn can tell you more, but very soft springs and atypical shock valving become necessary with the more massive bars.

What do you feel about the use of spindle spacers and/or modified uppers to reverse the camber curve?

Do you feel such heavy bars would be needed if the camber curve were what it should be?

Wayne, I don't have any experience with spindle spacers.I'm not sure they can be as strong as the OEM set up, but may be and work well. I'll be watching to see how your experiment works. As I am MUCH cheaper than you, I am looking for the most cost effective way to improve the car.Except for my own free labor, my car just isn't worth a lot of expensive parts.It was in rough shape when I bought it 9 years ago and I destroyed whatever collectors value it might have had long ago by ignoring it's cosmetic defects and doing things like the out of spec,homemade frame. For all these cars,I'll admit, camber control is a problem. The front suspension does behave very differently with lower springs than stock, and not necessarily better. Stiffer, shorter springs added to more compression and rebound in the shocks make anything more than 1 1/4 front sway bars questionable. These new bars offer a different approach. Allows experimenting along these lines. Extended wheelbase, rigid frame Impala. Full suspension travel[ front fender lip 28 inches off the ground, rear 28 1/2] with relatively soft springs [390lb. linear front, 120 lb. linear rear], low compression[1040f-1100r nm], very high rebound[2800f-4800r nm] shocks, and 1 1/2 inch front and rear short arm, straight run sway bars. The street rod frame Impala's weight distribution is now too different from OEM to be of much comparison value to someone running an OEM frame, but this car works far better than it's previous configuration and camber control is no longer an issue. Frame work alone did nothing to improve the handling when I still had the old suspension on it, but I could not have used such a radical suspension on the old frame.

LOL, didn't realize there was such a thing.

Actually I was hoping that this might put the handling where I want it without the usual(costly) aids. I don't mind the stock body roll, heck it rolls less than anything I've ever owned before, and I'm pleased with the ride now, I'd just like for it to stick a bit better.

Wayne, FWIW I suspect that even if you were finding used parts from different companies, matching diameter front and rear sway bars would be the best choice. Cheap way out would be to find both used bars around 32-33 mm.
