This new 3.75:1 turn to turn steering gear box is made exclusively for TOMS OFFROAD. This box is a heavy duty replacement for your factory power steering box or can be used to convert your factory manual steering to power steering. The mounting flange of our TOMS OFFROAD power steering gearbox is identical to the factory original mount so the three mounting holes go right into your frame. The internals of this box are larger than the original box, making them stronger and more durable. The o-ring style hoses ensure a better seal than factory hoses. This box has factory correct input and output so that the original shafts and pitman arm will install directly onto the box with no custom couplers or adapters. These boxes are made for us to our specification. Our supplier is an award winning manufacturer of OEM gearboxes. They have produced steering components for several major car manufacturers including Ford, Chrysler and others. This box is a quality piece made just for your Bronco by the industry's leading experts!

Input = 13/16" 36 spline

Wow!!! Couldn't be more happy!! Eliminated the super easy steering, feels like driving a new car. 3.75 ratio is WAY better!!! Eliminates the slop and feels super tight and sturdy. Running 33's Cepeks and no issues. Bought in kit with new pump also. Worked with the stock 73 steering shaft. Best money I have spent in a long time...

I installed this gear box on my 73. What a difference like night and day. A 100% improvement. There's no play in the steering and the response is wonderful. Bolted right in and bled easily. Best money I've spent on this this Bronco ever. I highly recommend this gearbox and Toms Bronco Parts.

Power steering on installed and I love it. The original was worn out.
