This CV axle shaft assembly is designed as a front left or front right replacement for select 2007-2020 Cadillac Escalade models. Built to OEM-level standards, it features a precision-machined 6-hole flange input shaft and 33-tooth external spline for secure fitment and smooth power transfer. The assembly uses alloy steel and carbon steel construction for durability under daily driving conditions. A sealed neoprene boot helps protect the joint from dirt and moisture while retaining high-temperature grease. It also comes with the output shaft nut pre-installed to simplify installation.
