\"Shock-Knock\" Noise Eliminator Bolt Package!
As many of you have come to find out, especially you SRT guys, the Viper is not a car free from noise. Well, in my R&D of the suspension setup on the SRT, I came upon a quite frightening discovery. One of Dodge's ingenious engineers made a mistake when they decided what bolts you use on the Viper's Shock Mounts. SOME HOW, this was never altered before release of the SRT. Oversight? Maybe. More than likely, though, a lazy part supplier or a penny-pincher was the cause.
There are two different type of bolts on the market, in regaurd to thread design. There is a "Cut thread", which is the standard bolt type. In this type, a standard shaft diameter simply has threads cut onto it, and thus the major diameter of the threads, and the shoulder that is left without threads on longer bolts have the same diameter. Secondly, there is what is called a "rolled thread". A rolled thread bolt has a thread diameter and a SHORT shoulder that is the same diameter as the thread- but the center of the bolt has a smaller diameter, usually 25% smaller. It just so happens, on the SRT-10 the shock bushings fall RIGHT ON THIS SMALLER SECTION!!! That means, that EACH shock bushing can move approx 1/4"! Add this up, and a lot of knocking can occur!
The bolt set I have for sale will eliminate this problem. It includes 8 bolts, and 8 washers- enough for all 4 shocks, upper & lower. These are an odd-ball sized bolt, Metric, in an oddball long length, in a higher than normal strength. In short; You aint gonna find these at any of your local shops! I had to special order a HUGE quantity, just to get them. I figured I would alert the Viper Club to this problem, and offer the remaining bolts out to the VCA. Price per set is 45.00, shipped to your door. This is not too much over my cost, I just want to get my money back.
Since installing, the shock noise I had in my car is GONE.
Here are some pictures that explain better than I do:
