Frequently Asked Questions
What problem does this kit solve?
The factory Ford CIII power steering pump used on 2003–2007 6.0L Super Duty trucks is known for weak performance, cavitation, premature failure, and poor steering assist with oversized tires or upgraded suspension components. This kit replaces the factory internals with proven Saginaw-style internals for substantially improved reliability, steering feel, and hydraulic performance.
What vehicles does this kit fit?
This kit is designed for 2003–2007 Ford F-250/350/Excursion equipped with the 6.0L Power Stroke
Does this kit work with hydroboost brakes?
Yes. This system is fully compatible with the OEM hydroboost braking system and is designed to properly support both steering and braking demands.
What pump pressure and flow is this system set to?
The pump is configured at:
- 1750 PSI
- 3.25 GPM flow rate
This provides significantly improved steering assist compared to the factory setup.
Is this better than a stock replacement pump?
Yes. Unlike most remanufactured stock-style pumps, this system was engineered specifically to address the weaknesses of the OEM CIII pump. Many factory-style replacement pumps still suffer from noise, low assist, cavitation, and short service life under heavy use.
Will this help with larger tires?
Absolutely. This kit is ideal for trucks running:
- Oversized tires
- Off-road setups
- Heavy towing
- Front lockers
- Snow plows
- RAM assist systems
The increased flow and pressure dramatically improve low-speed steering performance.
Does the kit include everything needed for installation?
Yes. The kit includes:
- Lee high-performance pump with pulley
- Proprietary pressurized reservoir
- Reservoir mount and adapter plate
- 6 GPM inline filter
- Return hoses and hose ends
- Mounting hardware
Beginning February 2025, the kit also utilizes the OEM pressure hose for easier installation and lower cost.
Does this fit trucks with the reservoir in front of the battery?
This standard kit is intended for trucks with the reservoir mounted behind the battery.
If your truck has the reservoir mounted in front of the battery, the kit can still be adapted, but some fabrication work may be required. Customers should contact Lee Power Steering before ordering.
What fluid should I use?
Lee Power Steering Fluid is strongly recommended for maximum pump life and reduced foaming.
Acceptable alternatives include:
- AC Delco non-synthetic power steering fluid
- Valvoline non-synthetic power steering fluid
Do NOT use:
- ATF
- Synthetic power steering fluid
Why does this reservoir design matter?
The included reservoir was specifically engineered to reduce aeration and cavitation by keeping the fluid stable during operation. Lower aeration helps reduce operating temperatures, pump noise, and premature wear.
Does the kit include a filter?
Yes. A 6 GPM inline filter is included to help protect the steering system from contamination and extend component life.
Is pulley alignment important?
Yes — pulley alignment is critical for belt life and pump longevity. Installation instructions recommend verifying alignment before operation. Improper alignment can cause premature pump wear and may void warranty coverage.
Can I install this myself?
Many experienced DIY mechanics install this kit successfully. However, proper hose routing, pulley alignment, and system bleeding are essential. Professional installation is recommended if you are unfamiliar with hydraulic steering systems. See 6.0L Pump Kit Installation Instructions.
Does this kit reduce pump noise?
Yes. One of the major benefits of the upgraded pump and reservoir design is reduced cavitation and whining commonly associated with the factory CIII pump system.
Is this compatible with RAM assist steering?
Yes. This pump kit works very well with hydraulic RAM assist setups and is commonly used as the foundation for high-performance steering systems. Lee Power Steering also offers complete RAM assist steering packages for these trucks.
What warranty is included?
The kit includes a 12-month limited warranty against manufacturer defects.
What are the typical lead times?
Lead times can vary depending on production schedule and demand. Customers are encouraged to call or email for the most accurate ETA before ordering.
