Inline Vibration Dampener
                        

Here's the solution to painful, tiring impulses that the roadway transmits through your steering system. Each end accepts a 3⁄4" DD shaft to allow inline installation between steering column and steering box.

A steering shaft support heim is recommended near the dampener for the most stable installation. Bright, nickel-plated steel construction. 3⁄4" DD female on one end, 3⁄4" DD male on the other.

Approximately 1-3/4" O.D. and 4" long end-to-end. Adds approximately 3-1/2" to the length of the shaft.
