Couplers & Adapters

USE THE FILTERS TO NARROW DOWN YOUR SELECTION

Using a 2” straight extension, called a coupler, to extend the steering box, R&P shaft or the column shaft, can sometimes eliminate a universal joint. The coupler can be welded or pinned to the un-splined end of a shaft. 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. Couplers are available in the same spline and Double D sizes as our universal joints. Couplers and adapters are available in steel and stainless steel only.
