The TeraFlex TJ shift link adapter kit will make shifting your 231 into all low range sectors simple. This adapter kit changes the trouble prone stock linkage which is not reliable due to independent body & drivetrain movement. The new bracket is bolted to the transmission & transfer case eliminating any negative movement. The heavy duty adapter kit is designed to provide problem free shifting even under extreme conditions. Fits 97-06 automatic transmissions. Does not fit Rubicon models. An extra long threaded adjustable turnbuckle shift linkage rod (947105) is available separately and highly recommended for longer linkage adjustment. An adjustable torque shaft rod (947120) is also available to fine tuning the linkage to the transfer case lever.
