Suspension Notice for S/SS by NHRA

Jeff Teuton · 12-13-2012, 05:49 PM

Anybody know just what they are aiming at? Maybe I'm just old and dumb (no comments). I looked at my stuff and really can't quite get a handle on it. I also looked at several old cars (Bruce, don't shoot me) and the configuration is basically the same from a 68 cuda, to present. I guess if you put bearings instead of bushings is the issue.

This is likely what they are talking about. I'm sure that GM cars have a similar set-up available to them.

it means don't put heim joints or spherical bushings on your front control arms

Rhodes, I can read that. I'm looking for the deeper inner meaning. I'm gonna choke you next time I see you. We been using aftermarket bushings on our stuff for so long it isn't funny. Mostly availability issue. There is some adjustment in the strut on all the older factory cars, none on the new ones. I know about the bearings on the control arms. Is that those things with the rollers in a cage that you grease? Or is that a mystical circular device related to Stonehenge that will explode on Dec 21. Only the Myans know for sure.

I've looked at that, read the description, and still have no idea what I'm looking at.

Sometimes there isn't a deeper meaning

Mike,

Those rods/shafts go from the lower control arm to the front of the K-member on each side.

What's unusual is that the NHRA statement specifies the strut rods in the header. But in the body of the letter, they talk about the entire front suspension in general!

So are they going to have suspension teardowns in the barn to look inside all of the pivot points now? Fords too!

I put a call in today to a NHRA tech guy to help clarify what is meant by the wording in the post. I do not believe it is a worry to the GM cars, but could effect the Fords and Mopars with the front strut rods. Remember how an old Mopar would shimmy the front tires on lauch sometimes, that is what will happen again if this rule is enforced. The front strut rod has to be secured and stable for the car to run safely, especially at 150 plus MPH. This will not happen with the old Mopar setup, a long rod with two rubber bushings trying to hold it steady. Dyno
