"Zone Offroad's new transfer case indexing ring kit for 2009-2013 Ram heavy duty trucks. Zone's kit features a slimmer design with high quality ARP-brand mounting studs, CNC machined, billet-aluminum front driveshaft spacer and longer mounting hardware. The slimmer design maximizes spline engagement and improves front driveline angles on 6 or 8 bolt transfer case equipped Rams, allowing use of the factory front driveshaft with 6-8"" lift kits by relocating the transfer case output. This changes the front output flange position and helps eliminate driveline vibrations that may occur with larger lifts. | Zone Transfer Case Indexing Kit D5623"
