Dynatrac sells its Pro60-IRS conversion for '08-and-newer LC and LX Mopars either complete, bare with just the 35-spline stub axles (for DYI guys), or virtually any state in between. The Dynatrac nodular-iron housing uses rugged Dana 60 internals, including a choice of 3.54–7.17:1 gear-ratios (3.54:1 is used here). RCV chrome-moly halfshafts with beefed-up CV joints are said to be the strongest available.
