• Includes OE-spec pitman arm and nut designed for larger 45mm sector shaft
• Eliminates excessive on-center steering wheel play
• Prevents electro-hydraulic pump overheating under heavy loads
• Mechanical belt-driven pump replaces problematic electric pump
• Hydraulic assist cylinder acts as dynamic steering stabilizer
• Relieves stress on steering gearbox and frame mounts
• Improved turning capability with locking differentials engaged
