Ensure transmission output shaft has enough spline length to compensate for the extra yoke travel. Output shaft modification may be necessary to prevent bottom-out.
Extended length slip yokes help compensate for extreme-travel rear suspension applications, or driveshaft lengths that are slightly shorter than necessary. Sonnax extended length performance slip yoke T2-3-6081HP8XL is forged from a chromoly billet to provide superior strength and performance for dirt oval track racing with above listed transmissions.
Some slip yokes have missing splines. To verify spline count, always count the splines on the transmission output shaft. A slip yoke counterbore is a short lead without spline in the end of the yoke.
