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 Powerglide 2-piece that dramatically reduces transmission changes.
