Borgeson Splined and Double-D Shafts

Product images may differ from actual product appearance.

Borgeson recommends splined shafting as it is a simple and safe method of attaching your steering components. If phasing needs to be slightly adjusted because of a ''tight spot'', you can easily index or rotate a spline shaft in small increments. The drawback to Double-D shafts is that the phasing is fixed. However, using Double-D shafting is preferred over welding and/or pinning done by a certified welder. Overheating the bearing which causes premature failure is often associated with welding. Pinning requires that holes be drilled in shafting causing weakening of the shaft. Vibration can cause a pin to back out or become loose in the hole so it is necessary to use a safety backup such as a hose clamp or safety wire in conjunction with a pin.
