Borgeson Steel Steering Couplers

Product images may differ from actual product appearance.

Often a u-joint can be eliminated by using a 2'' straight extension, called a coupler, to extend either the steering box, R&P shaft or the column shaft. The coupler can be welded and/or pinned to the unsplined end of a shaft. The 1''-48 and 1''-Double D couplers have a 1-1/4'' hole that will accept either an adapter to reduce inside diameter to 3/4'' smooth or another splined or 3/4'' Double D coupler. The coupler assembly would have to be pinned and/or welded together. Welding the coupler is acceptable because there are no moving parts to damage, and the coupler's steel is less susceptible to heat damage from welding. As an alternative, you can use a Vibration Reducer as a coupler to extend a short shaft, since the Vibration Reducer now comes with female ends to fit many popular applications.
