At this time we know of only one company making the Omega clamp style suspension link bodies, Coleman Racing. This is our preferred component but any type of link with the proper threads and length will work. Coleman Racing also makes a line of lock nut style links, as do Steinjager, Summit Racing and Speedway Motors.
It is important to note that any suspension link body to be used must have a 5/8"-18 UNF Right Handed thread on one side, and a 5/8"-18 UNF Left Handed thread on the other. UNF stands for "Unified National Fine", which describes the type of thread. In many cases product descriptions may only list the 5/8"-18 for thread information. This is fine as the UNF is implied by the 18 thread pitch.

AN IMPORTANT NOTE ABOUT METAL PLATINGS
Many of the link bodies you will find will have a plating on the metal. Some platings build up a very thin layer of corrosion protective material on the metal and this means that depending on how the threads in the part have been cut, after plating the thread might be a bit smaller than intended. This can cause the rod end to be very difficult to thread into the body.
In most cases this can be fixed by "chasing the thread" with a tap after the plating. But given the size of the threads and the fact that one of them has to be a left handed thread, these may not be tools that everyone has.
It is this characteristic (especially on the red anodized aluminum bodies) that has given rise to our "special order" suspension kits. These kits use the omega style locking mechanism on red anodized aluminum bodies. Each body, after it is received (having been anodized at this point), is set up and the threads are re-cut to ensure that they are properly sized and clean. Then each end of the suspension link is assembled with a rod end and the fit between the rod end and the body is checked, and if necessary, reworked, until the fit is correct, ensuring proper fit and function.
You may want to check with the company you are purchasing your suspension bodies from to inquire what kind of material and plating is being provided and if there is a chance that the thread may be under-size after plating. Or if they chase the threads after plating.
Building Your Own Suspension Link
If you are purchasing one of our "Build Your Own" suspension kits you will need to also purchase the suspension link bodies to complete your suspension. There are a number of companies that make the parts you will need and we have found that this offers our customers a greater variety of materials, colors and finishes to customize their suspension. It also offers a bit of a cost savings over our fully assembled kits. The characteristics of building any of the suspension links for the C4 are very similar. The differences are the length of the link body and type of locking mechanism for the rod end.
There are two methods of locking the rod end in place once the length of the suspension link is set. The first, which the Banski MotorSports preferred method, and the one that our kits have used from the beginning is the omega clamp (see FIG 1 & FIG 2). The second is a more traditional lock nut (see FIG 3).
