RTS offers superior transmission yokes in a heavy-duty forged 4340 chromoly construction with a 1350 universal size to fit most popular transmissions. Fully heat-treated to achieve optimal tensile strength, RTS’ transmission yokes are then machined to ensure concentricity and balance for ideal driveshaft operation. Plus, RTS also offers specially heat-treated (case-hardened) yokes for your roller-bearing extension housings.
