Sway bars

Hellwig #55917 is the “pro touring” front sway bar, it puts the sway bar tabs in a similar spot as the 73+ cars and increases tire clearance. If you’re planning on 17+ rims and anything 245mm or wider for tires in the front you need the #55917.

If you want to have the stock 67-72 sway bar tab locations on the LCA’s, Hellwig #5906 is what you need. It can be used with the factory LCA tabs. But that bar will limit tire width to about 235mm max.

Hotchkis also makes a very nice bar for the 67-72 cars, but it’s more expensive and functionally isn’t much different than the #55917. The Hotchkis bar, like the 55917, will not work with the factory 67-72 LCA tab locations. Which doesn’t matter unless you have LCA’s from a factory sway bar car.

Sanity check. Supposedly this is going to be a street car / driver. At least that is what I tell myself.

So... I have a '68 A-body with a '75 K-frame and QA1 LCAs. I have what I think is an ADDCO '73+ sway bar for the front that I purchased and installed about 25 years ago currently on a shelf. It is yellowish and 1-1/8" solid bar. I have FF 1.12" torsion bars, welded and reinforced K-frame, Borgeson PS, roller bearing idler, and the sector shaft support. I have Spax adjustable shocks. Plan is for 275/35-18 or possibly 285/35-18 tires. Front brake is Dr Diff "stage 4" with the Viper style 4 piston and 13" Baer rotors.

Q1: If I want to go to the lighter Hellwig bar then 55905 is my bar I assume?

Was debating going up to the 1.18" torsion bars, but want to drive it first.

On the rear, springs are mounted in the frame. Mini-tubs and some other clearance enhancements. Debating sliders. May run as large as 355/30-19. Dr Diff 11.7" rear brakes with Baer rotors.

Q2: Rear bar that fits is Hellwig 6908 (E-body) in my case? Does anyone have one mounted with the narrowed inboard springs and can show picture where end link attaches and clearance to spring?
