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 in a variety of applications, including those listed here.
Talk with a transmission builder or driveline shop to verify your vehicle's output shaft style.
Measure OE slip yoke with a precision tool to determine which Sonnax yoke you need. Centerline to end length, journal size and U-joint series are critical dimensions requiring accurate measurements.
*U-joint bores in yoke will be slightly larger than the actual U-joint dimensions given in the chart below.
