Description
The Chelsea 442XWGSX-W5XR or 442XWGSXW5XR is a 442 Series Power Take-Off assembly built for air-shift operation at a 0.391:1 gear ratio. It mounts via standard mount with metric studs and delivers output through a 1-1/4″ round standard shaft. The housing is cast iron for long service life, and the low-profile shift cover helps where clearance is tight. Output flanges are rotatable for easier installation in confined spaces, and the output shafts are greaseable for extended service intervals. This unit runs without pressure lube. Call us to confirm proper fit for your truck and transmission application.
