Saginaw Power Steering Pump Upgrade Kit For Ford F-250/F-350 7.3 1999-2003 Models
36$1,049.00
Product Details
The 1999-2003 Ford F-250/F-350 with the 7.3 motor is a great workhorse. Unfortunately, the power steering system can only handle street and light off road usage. When you use it as a tow vehicle and need to do extended periods of low speed steering (backing a trailer), or modify it to larger tires, the OEM pump falls short and will often fail.
Our Power Steering Pump Upgrade Kit replaces the stock Ford steering pump with our High-Performance Saginaw N-pump that has been modified with a ported housing, chromoly shaft, needle, and thrust bearings. This is the same pump that many of our off-road race teams are using to win the Baja 1000!
This kit also includes:
- CNC'd pump adaptor bracket that will bolt to the OEM bracket
- proprietary design 3.5” x 10” reservoir
- pressure hose
- return hose
- all necessary mounting hardware
Our reservoir uses a unique design to keep steering fluid perfectly still. This results in zero cavitation and reduces air in the system – which keeps operating temperatures lower, resulting in longer pump life. Our pressurized reservoir also keeps oil in and dirt out.
We do recommend adding our 6GPM in-line filter when doing the install to even better protect your system. If adding a filter, choose barbed fittings for easy installation. View Filter
If your vehicle has tires 37" or larger, we recommend using hydraulic ram assist. When adding a ram your pump will need higher flow. We offer this pump with a larger liner and billet end cap to handle the extra flow requirements for the ram. +$150
View Installation Instructions
When using this pump kit, you MUST use the radiator hose that routes "through the serpentine belt". This is the more common hose, but some vehicles came equipped with the "around the belt" hose. If you need to change the hose, the Gates part # is: GAP22542.
Fluid Recommendation
It is HIGHLY recommended to use our specialty formulated Lee Power Steering Fluid.
AC Delco or Valvoline non synthetic power steering fluid will work as a second choice but do not have the same Wear and Anti-Foaming additives our fluid has.
DO NOT USE ATF OR ANY TYPE OF SYNTHETIC FLUID.

Problem solved
Great service when I called on the phone. I’m running 3 trucks with the 7.3 psd. Not sure why but my wife’s truck had gone through 3 power steering pumps so I decided to give the Lee upgrade a try. So far it seems to be working perfectly. I think our power steering problems have been solved

Awesome product!! Worth every penny!
Excellent!! I’ve been chasing my tail with the stock pumps. Very well made and engineered.

Great performance, very noisy
My experience with Lee was amazing. The first pump I ordered was malfunctioning so they sent me a new one free of charge. The pump is on my 2002 F250 and is paired with my psc hydro assist and the performance is wild. It steers easier than my 2013 F350. However, my only gripe is that it makes a lot of noise inside the cab, lots of noise. With that being said, I’d still recommend this product

Great steering but noisy
Lee was very gracious and helpful when the original pump I bought was defective. They sent me a new one and didn’t charge me a dime. I’ve had the pump on about three days now and it’s a tremendous difference. No more kick back from psc hydro steer. It’s like driving a brand new 6.7 super duty. However, the whining worries me. Is there something wrong or will it just be noisy?

Wish it had lasted.
Perfect to start with. But After a 3 weeks starting to make a good bit of noise when under a load.
