Strange offers superior transmission yokes in heavy-duty cast steel and 1350 Series chromoly to fit the most popular transmissions. Fully heat-treated to achieve optimal tensile strength, Strange chromoly transmission yokes are machined to ensure concentricity and balance for ideal driveshaft operation. Plus, they also offer specially heat-treated (case-hardened) yokes for your roller-bearing extension housings and chromoly Powerglide 2-piece that dramatically reduce transmission changes. For both racing and street use, Strange transmission yokes are a solution to failure-prone stock yokes.
