The 2Low kit provides the benefit of true low range gearing, while allowing the front to freely turn. It lets you choose 2Low in addition to the other standard options. The 2Low kit will eliminate drive train bind and most of your tight trail three-point turns. This kit is completely internal and does not require any external modifications.
The new shift pattern is: 2H > 4H > N > 4L > 2L.
Note: Fits 231-J transfer cases only.
