The Tera Low231 conversion kit is the best solution for providing Wranglers, Cherokees, and Comanches with low crawl ratios. This kit increases rock-crawling performance without affecting the high range for the trip to and from the back country.
  It provides true 4.0:1 reduction without the noise of older planetary systems. Every part in this kit is new; there are no core charges. Shift linkage and driveshaft length changes are not necessary.
  The Tera Low231’s high input torque rating suits it for use with V8 engines. Each Low231 is covered with our exclusive two-year warranty.
  The Tera Low231 is compatible with the 2WD Low-Range Shift kit (Part #2LOW231) and the TeraLow Short Shaft kit (Part #231SS).

Heavy-Duty Rear Output Shaft for the Dana 300
This kit replaces the stock output shaft of the Dana 300 transfer case with a heavy-duty output shaft. The new shaft is better suited for high-torque and high-stress situations because it is thicker and stronger. It is great when combined with the Low300 gear set because of its additional strength. (Part #HD300S)

Note: This kit is designed to be used on the Dana 300 transfer cases that originally had the longer tailhousing. Bolt pattern differences prevent this kit from working with the shorter tailhousing design.
