Weight Tech: Manual Steering versus Power Steering

There are many different rumors about how much weight can be removed from a Mustang by swapping out the power steering system for a manual steering rack. To put the false rumors to rest, we pulled out a scale and weighed the parts.

The difference in weight between a complete Fox Mustang power steering system and a manual steering system is 16.15 pounds.

Power Steering (Fox Mustang) Weight (lb)
Rack with inner tie-rods 14.28
Pump, aluminum bracket, pulley, and hardware 10.30
Low pressure hose assembly 0.45
High pressure hose assembly 1.45
Fluid (1.7 pints) 1.19
Accessory drive belt 0.58
Total 28.25

 

Manual Steering Weight (lb)
Rack with inner tie-rods 11.60
Accessory drive belt 0.50
Total 12.10

 

In this example we assume that the change in belt routing necessitated by eliminating the power steering pump requires only a shorter belt, and that no additional components are needed to aid with belt routing.
