The TeraFlex JK Rubicon 241OR 2Low 2WD Low-Range Shift Sector Kit adds a rear 2WD (two-wheel-drive) low-range option to the JK Wrangler Rubicon 241OR transfer case's standard low-range shift pattern. This kit enhances trail turning ability by allowing tighter turns on narrow switchbacks and eliminates most front-end bind encountered with turning with 4WD (four-wheel-drive) engaged. This internal modification does not require any external upgrades.
