Zone has re-designed their transfer case indexing ring for the Ram 2500 and 3500. This thinner design features ultra strong ARP brand mounting studs along with a Billet aluminum front driveshaft spacer that is CNC machined, and longer mounting hardware. This design improves front driveline angles on 6-bolt transfer case Ram trucks by maximizing spine engagement. When installing a 6" to 8" lift, the factory front driveshaft can be retained by rotating the transfer case output. By improving the front output flange position, this helps eliminate driveline vibrations that often occur with installation of a taller lift.
