TeraFlex Suspension 4444401 NP231 Short Shaft Kit for Jeep Wrangler YJ/TJ/XJ

The TeraFlex NP231 Short Shaft Kit is designed to increase rear driveshaft length by 4 inches on Jeep Wrangler YJ, TJ, LJ, and XJ Cherokee models equipped with the NP231 transfer case. This modification eliminates the need for a transfer case lowering kit in most lift applications, providing a cleaner installation and improved driveline geometry.

Key Features:

• Extends rear driveshaft length by 4 inches for improved driveline angles
• Eliminates transfer case lowering kit requirement in most applications
• Includes upgraded larger output bearing for increased durability
• Complete kit with rear output housing for direct replacement
• Stronger transfer case rear output shaft
• All necessary hardware and seals included for complete installation

Kit Includes:

• Transfer case rear output shaft
• Output housing with upgraded bearing
• Output housing seal (#231104)
• Rear output yoke (#3244404)
• Output yoke flanged nut (#231112)
• All mounting hardware

Compatible Vehicles:

• Jeep Wrangler TJ (1997-2006 short wheelbase)
• Jeep Wrangler LJ Unlimited (2004-2006 long wheelbase)
• Jeep Wrangler YJ (1987-1995)
• Jeep Cherokee XJ (1984-2001)

This short shaft kit is ideal for lifted Jeeps where driveline vibration and CV joint binding are concerns. By lengthening the rear output shaft, the kit allows for a more favorable driveshaft angle, reducing stress on U-joints and improving drivetrain longevity.
