Power Steering was an option in 73-77 Ford Broncos and today is one of the most popular upgrades among early Bronco owners. Our quick ratio power steering kits are an excellent upgrade from manual steering or from factory power steering. The stock power steering gear box in 73-75 was a 6 turn box. In 1976 & 1977, Ford changed this over to a 4 turn box to provide more responsive steering. Our quick-ration power steering conversion takes it one step further with a 3.1 turn box. This means the box can be turned from lock to lock with 3.1 turns of the steering wheel.
