Splined Sleeves & Slip Assemblies

A slip assembly is one of the most mechanically demanding subcomponents of any driveshaft — it needs to telescope smoothly under load, maintain alignment under rotation, resist contamination in harsh environments, and do all of this thousands of times over the life of the vehicle without developing slop or binding. Our splined sleeves and slip assemblies are machined to tight tolerances, with spline profiles that mate cleanly and slide freely without excessive clearance. We carry individual splined sleeves for custom fabricators as well as complete slip assemblies for builders who want a tested, ready-to-install solution. Whether you’re replacing a worn assembly or speccing out a new custom shaft, you’ll find the right combination of tube size, spline count, and series here.
