The Mopar/Dynatrac JK Rubicon Dana 44 for TJs is built by Dynatrac to TJ specs (tube length and bracketry). It features a JK Rubicon third member and heavier tubes than the OE JK Dana 44. Available through Mopar dealers or directly from Dynatrac, it’s a smart choice for those who want to improve their TJ Wrangler. A set of 4.88 gears and a Rubicon E-locker were used in the Rubicon TJ. Currie’s TJ CurrectLync tie rod/draglink system is strong and reliable.
