Slip Yoke 6-3/4in

The Allstar Performance Slip Yoke 6-3/4in (ALL 69042) is a 27-spline slip yoke engineered for use with popular automatic transmissions including the 700R4, TH350, and manual gearboxes from Bert, Brinn, Muncie, and Saginaw. This steel component serves as a critical driveline interface, allowing controlled axle shaft extension and retraction during suspension articulation while maintaining secure driveshaft coupling. Slip yokes are essential in performance and off-road applications where suspension travel demands axle length variation.

At 6.750 inches in length with 27-spline geometry, this yoke accommodates the standard spline count found across fourth-generation Chevrolet automatic transmissions and high-performance manual boxes common in street rods, drag racing, and off-road vehicles. The natural steel finish provides a baseline platform for powdercoating or additional surface treatment if desired. Weighing 2.18 lbs, the yoke integrates into driveline assemblies with minimal mass penalty. The 27-spline profile ensures repeatable concentricity and reliable torque transmission under load.

This component is designed for builders and restorers working on vintage muscle cars, modern restomod platforms, and performance street vehicles where driveline integrity directly impacts safety and driveability. Whether rebuilding a classic hot rod, upgrading a four-wheel-drive recovery platform, or assembling a drag car, correct slip yoke selection prevents binding, excessive play, and premature bearing wear. The 6-3/4in length fits compact driveline configurations and suspensions with moderate to aggressive travel.
