This transfer case indexing kit repositions the front output flange and helps eliminate driveline vibrations that can occur at taller lift heights. The thinner design maximizes spline engagement and improves front driveline angles on 6-bolt transfer case equipped Ram trucks, allowing for re-use of the factory front driveshaft (with help from a spacer) on 4-6.5" lifts. Also included is a bolt-in replacement crossmember with an integrated transmission mount for improved front driveshaft clearance.
