Product Description

Borgeson Power Steering Conversion Kit for all 1965-1966 Mustangs with a 289 Engine.

Upgrade your Mustang's manual steering to power steering with this quality power steering conversion kit from Borgeson! Borgeson's steering box integrates the power assist into the assembly, allowing you to eliminate the power steering control valve and slave cylinder. The stock power steering system is notorious for leaks and providing a vague and over-boosted steering feel.

This kit features a sporty 14:1 ratio re-manufactured modern integral power steering gear box that provides benefits over a traditional rack & pinion conversion, while still offering a similar steering feel and an original look. Each box is carefully assembled, adjusted and inspected to standards that surpass OEM. Does not increase the turning radius like most rack & pinion kits.

Installs easily with simple hand tools and without removing the engine. Includes all necessary components for the conversion. Features a 3 year manufacturer's warranty on the steering box.

-Saginaw power steering pump with mounting brackets
-Power steering box
-Power steering hoses
-Steering coupler
-Replacement steering column shaft with floor mount

*Will require a 2-groove crank pulley (not included).
*Will also fit 1967 Mustangs with a 1" sector shaft.
*Will NOT work with factory z-bar clutch linkage. Must use Borgeson's z-bar if you are using the factory clutch linkage.
*If you want to add headers to your 289/302 with Borgeson Power Steering our shop recommends using Tri-Y headers. Larger diameter headers may have clearance issues.

Borgeson Power Steering Conversion Kit 289 1965-1966 is rated 4.0 out of 5 by 2.
Rated 5 out of 5 by from Great Upgrade I purchased this product to upgrade from manual steering. All the required parts are there as well as an instruction booklet to guide you through the process. Beside the improve my steering I did notice a little bit better turn ratio getting in and out of the garage

Rated 3 out of 5 by from dissapointing pump bracket Absolutely no effort went into designing the pump mounting bracket. Sticks the pump way out in no mans land with no real bracing. Looks terrible! 0 stars for aesthetics. I threw mine in the scrap bin and bought a cvf racing bracket. steering box and the rest of the kit mounted up as expected and work well. If I were to do this again I would buy the box and column shaft separately and source my own bracket and pump. It would cost about the same.

Product Questions


will this conversion for my 65 mustang work with headers by Jegs 555-300130.

Asked by: kramers89
Unsure - we don't sell Jegs products, so we just don't know if it would fit with this part.

What fan belt do I use? Do I use a 2 belt set up?

Asked by: Pens
No mention of the fan is made in the literature for this product, as it's a separate system.

Will the Flowtech Long Tube Headers 1-1/2" Primaries Black 289 1965-1970 work with this or would i have to go with the factory style power steering to work with my exhaust system which is the Flowmaster Cat-Back Exhaust Kit 2.5" for long tube headers65-66

Asked by: Connor15
From reading the literature on this part, I suspect your long tubes are going to be problematic. You'll most likely want the factory style steering.

Thank you for answering my previous ratio question (16:1 vs 14:1), but this is the Borgeson description:

Asked by: 1966ford
We have confirmed with the manufacturer that it has, indeed, changed to 14:1.
Answered by: CJ Pony Parts
Date published: 2015-05-05

The product description lists a 16:1 ratio, however, Borgeson literature indicates a 14:1 ratio. Can you please confirm?

Asked by: 1966ford
Most others report a 16:1 as well, so unless Borgeson tells us otherwise, we believe our information to be correct.

I already have headers installed.  Not sure brand as they were installed when we bought the car.  Is there a way to tell if the borgeson power steering unit will fit by measuring clearances?

Asked by: Jacks Stang
Unless they're Tri-Y headers, you will likely have clearance issues with this kit. We don't have any measurements available to help you in telling whether it will work with the setup already in your Mustang, unfortunately.
