The TeraFlex Extreme Short Shaft kit is what short wheelbase Wrangler owners have been dreaming of for decades. It is over 3" shorter than a standard SYE kit, and 1-1/2" shorter than an ATLAS II. The Extreme SS kit comes with all necessary components to modify the stock 231 case. Speedometer readings are transferred through a tone ring and electronic sensor.

Product Details:

  • Improves on strength
  • Increases drive-shaft lengths by up to 7" over a stock application.
  • To adjust the calibration a converter box is necessary to make any calibration adjustments.
