PSC Big Bore XD Cylinder Assist Steering Gearbox for 2003-2006 Jeep TJ / LJ

The PSC SG400R Steering Gearbox is the best solution to replace the failure-prone small piston Mercedes ZF steering gear that was originally installed on 2003-2006 Jeep TJ and LJ.

Fits:

• 2003-2006 Jeep LJ/TJ

Features:

• 100 Percent New
• Saginaw Type Replacement for OEM ZF Steering Gearbox
• Larger Piston Diameter delivers Increased Torque Output for Upgraded Tire Sizes and Locking Differentials
• Modified for Adding Steering Assist Cylinder
• Billet Aluminum Top and End Covers
• Turning Ratio: 14:1, 3.25 Turns Lock-To-Lock
• Input Shaft: 3/4 Inch - 30 Spline
• Port Type: Metric O-Ring
• Mounting: Three (3) Bolt, Inside-the-Frame
• Threaded Ports are machined directly into the gearbox housing for -6AN fitting connection to PSC Steering Assist Cylinder. Unlike welded fittings, this reduces the risk of a fitting breaking off due to an overextended hose assembly. Replacement fittings can easily be serviced if necessary.

Tech:

• PSC-HK2000 High Pressure Hose Assembly required for easy installation.
• Due to the increased overall size of the SG400R, some applications may require a 1" body lift to clear interference issues of the high pressure and return lines. 
• Some applications may require the modification of the factory steering shaft, shortening it by approximately two (2) inches. How to Shorten Your Intermediate Shaft
• Installation of Jeep/MOPAR Intermediate Shaft PN 52078705 is required

Notes:

• Due to the increased overall size of the SG400R, some applications may require a 1" body lift to clear interference issues of the high pressure and return lines.
