If any W126 owners are interested, we're doing a group buy for 19mm Heilwig rear sway bars for second generation W126 chassis cars.

If you're not familiar with this, the stock rear sway bar is 14mm but an increase to a 19mm bar really makes a big difference in the way the rear of the car handles.

If you would like more details or want to get in on the group buy, you can go here for more information. This will be the third group buy we've done for these, as each time more and more people want in on it as the reports from the folks who have gotten them have been great!

Thank you,

Dan

The change from 14mm to 19mm cannot help but make a noticeable difference: the torsional stiffness of the bar is increased by a factor of 3.4!

From the postings on BW, it might be concluded that the bar being offered is applicable only to cars without anti-squat linkages. If so, that would exclude 500s and 560s as delivered in the USA. LWB250, can you confirm either way?

Frank,

I believe this was an issue with the first group buy we did, and I'm not sure if it was resolved - I think it was. Please let me check and I'll post back here with my findings.

Also, if you have a car with SLS you will have to grind a small flat on the bar for your SLS valve lever. Plenty of folks have done this without issue. If you read the BW thread on these it's addressed there.

Thank you,

Dan

Without pictures I can't comment on the compatibility with the anti-squat suspension, whatever differences there might be. There is a thread on Benzworld about anti-squat suspension in 500SEL and 560SEL models that may be what you're referring to, and if so, this bar will not work.

I can tell you that if the stock sway bar is a part number 126 326 48 65, the upgraded one should fit as a direct replacement. Bushings and brackets are supplied with the new sway bar.

It won't fit Gen 1 cars, which have a completely different sway bar and link setup as pictured below. This may well be the same as the anti-squat system you reference.

The price will be at or very close to $230 shipped anywhere in the CONUS. We have a few international participants, so if you're not in the continental US, let me know any way and I can put you in touch with our shipping guy.

Re: Thumbnail in post #4 above

The bar end, and connection to the wheel carrier that is illustrated in the thumbnail is the design used with anti-squat geometry for all W126 model years, both GenI and GenII.

Those GenI cars (the great majority) that do not have anti-squat use the same anti-roll bar (ARB) configuration as the one that is being offered by the OP. The quick way to identify those cars that will accept the replacement ARB is to look at the semi-trailing arms: steel - yes, aluminum - no.

The bottom line is that most GenI W126 cars will accept the ARB that is on offer.

Thank God there are 126 Fanatics like me !
I'm down for 1/one maybe 3/three.
Helwig makes a fantastic adjustable solid "dogleg" endlinks. Stronger, adjustable, & cheap. As I recall a pair is less than $30.00 US. Well worth the money. Makes a thin swaybar feel thick. Anyone email or hit me back asap. Can't miss out on Santa this time. Thank You !

That has not been the case for Gen 1 owners who have attempted to use this sway bar. I am not going to get into a debate over fitment - we will only guarantee that it fits Gen II W126 models with the link setup, nothing else. If someone wants to use it on anything else they do so at their own risk, as these are not returnable.
