A u-joint can sometimes 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. We offer shafts that are splined only on one end in 3 lengths: 5", 16" and 36". The 1"- 48 and 1" DD 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" DD 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 VR now comes with female ends to fit many popular applications. Couplers are available in the same spline and Double D sizes as our u-joints. Couplers and adapters are available in steel and stainless steel. Aluminium couplers and adapters are not available.
