Q & A

What's in the Box

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.

If you've got spherical rod ends on your vehicle, you'll probably need jam nuts. You might also need them for tie-rod ends or other types of fittings and connectors. Our jam nuts are made from premium steel (zinc-coated for corrosion prevention), and they're available with either right hand or left hand threads.

These steel fine thread jam nuts are for use with rod ends, heim joints, and clevis.

NOTE: This DD shaft is only milled with flats on both ends for 1" of length of the shaft. It is not milled the entire length of the shaft and therefore, can not be cut to length unless it is going to be welded to a 3/4" round or has new flats milled into the end. Please see Flaming River DD shaft if fully machined DD shaft is required.
