JB Conversions supplied this NVG241OR Rock-Trac JK Rubicon transfer case. The 'case features a low 4:1 low range and is very strong. Look for a detailed feature on the JB Conversions NVG241OR Rock-Trac transfer cases soon. This isn't the Tom Wood's driveshaft. It was on there so the shop could move the TJ around before the TW driveshafts arrived.
