Jam nuts, in our opinion, are one of crudest locking systems used. And one always hopes they don’t strip or round the hex on either a turnbuckle body or the jam nut itself. And don’t forget that one side of that system is likely a left handed thread. Good luck finding a left handed nut on a Saturday or Sunday afternoon when you’re working on your beloved C4.
Don’t forget the sizes you’re dealing with either. Typically current systems require you to get a pair of wrenches, usually AT LEAST ¾”, under the car and to the end of the link to tighten the jam nut. Once you do that often times there is not enough room to get the leverage necessary to properly tighten it.
Collets, like those used on machining centers, lathes and bridgeports securely grasp almost the entire circumference of whatever round shaft they’re used with. As the fingers of the collet are tightened it firmly holds the shaft, and whatever is connected to it, in place. All of our suspension links have a collet like feature on both ends. This collet is tightened by a unique system called an “Omega clamp” (called Omega because the clamp resembles the shape of the Greek letter). The Omega clamp uses a small 1/4" screw that has a 12 point head, so all you need to tighten your components once you have set the length is a 1/4", 12 point socket (not supplied). As the screw is tightened it pulls the Omega clamp closed which squeezes the collet that holds the rod end. Since the force used to close the Omega clamp is distributed over a large area, there is less likely to be damage to the link body, Omega clamp, or rod end.
And imagine how much easier it will be to get a 1/4" socket in a tight area to secure the length of your suspension links.
