Strange stocks Spicer heavy-duty 1350 series yokes and a superior line of 1350 series chrome-moly transmission yokes for the most popular transmissions. Chrome-moly transmission yokes are machined to assure concentricity and balance for ideal driveshaft operation. Each Strange yoke is fully heat treated to achieve optimal tensile strength. Strange also produces a specially heat treated (case hardened) yoke for roller-bearing extension housings and a chrome-moly power glide 2-piece that dramatically reduces transmission changes.
