Overview
This transfer case indexing kit repositions the front output flange and helps eliminate the driveline vibrations that can occur at taller lift heights. The thinner design maximizes spline engagement and improves front driveline angles on 8-bolt transfer case equipped Ram trucks, allowing use of a driveshaft spacer to re-use the factory front driveshaft when installing a 6-8" lift kit.
