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.
