The Tera Low231 conversion kit is the solution for providing Wranglers, Cherokees, and Comanches wit low crawl ratios. This kit provides rock-crawling performance without affecting high range gears for daily drivers, or the trip to and from the back country. It provides a true 4.0:1 reduction through a heavy duty 5 gear planetary system. Every part in this kit is new, with no core charges. Shift linkage and driveshaft length changes are not necessary. The Tera Low231's high input torque rating will handle extreme torque applications. Each Low231 is covered with our exclusive two-year warranty. The Tera Low231 is compatible with the 2WD Low-Range Shift kit (2204000), the TeraLow Extreme Short Shaft kit (#4444400), and the Short Shaft kit (#4444401). Note: Because these low-range gear sets increase torque by up to 50 percent,some large or high-performance engines may contribute to premature drive train failure.
