JK/TJ RUBICON LOW RANGE SWITC

TJ Rubicon, JK Jeeps & Power Wagons with a NP271 (Low Range Switch):

This kit is a quick fix for the Jeep TJ Rubicon’s, JK’s & Power Wagons. This kit tells the computer system that the vehicle is in low ratio, disabling the ESP on JK’s and enabling the locker option on the TJ Rubicons & Power Wagons.

This kit will not light the 4WD dash light in high range. It will work on the Jeep JK’s, however, Kit 300377 is a control module that keeps all the stock Jeep functions as well as the dash light in 4WD high. The 300377 is the most recommended kit for the Jeep JK’s.

NOTE: This Kit ( is for use on Vehicles with Atlas Transfer Case Production date of pre August 2014. If your Atlas production date is post August 2014, you will need part number PN300378A
