Yukon's 3/8" x 1-1/4" ring gear bolt is intended for 1955–1964 GM passenger cars equipped with Auburn Positraction, offering a direct replacement bolt to secure the ring gear in those classic housings. The correct length and thread help ensure proper clamp and gear mesh when reinstalling the differential. Yukon supplies other small differential parts to finish period-correct repairs.
