Overview
RCV Custom Big Bell CV Axles
RCV Performance custom Big Bell CV axles are the ultimate solution designed to fit 2005+ Ford F450 and F550 Super Duty applications, as well as big knuckles like the Reid Super Kingpin knuckles for Ford Super-60 unit bearings. The Big Bell CVs are RCV's 2.5 ton Rockwell CVs, but the outer stub is designed to fit directly to the large 32-spline 2005+ Ford Dana 60 "Super-60" unit bearing. This eliminates the need for a lock-out or drive flange, increasing strength and reliability. These kits are designed for custom axles. The Big Bell CV is able to accept a 40 or 47 spline inner axle.
