STEERING BOX (HEAVY DUTY UPGRADE) - DELPHI ('94-'02, 2500/3500, 4WD ONLY) NO CORE CHARGE

Description

Are you looking to replace your 4WD Dodge Ram's OEM steering box with one that lasts longer and provides better input? It's hard to beat our remanufactured heavy-duty steering box that features a number of upgrades.

Your truck's original steering box was engineered in the 1960s, called a Series 700, and was made by Delphi. The replacement unit is also made by Delphi, but it was designed in the 2000s and it is called a Series 680.

So what makes the Delphi Series 680 a better mousetrap?

• Modern internal valving provides a variable assist feel to the driver's steering input. The further you turn the wheel the greater the assist. The benefits to you: the power assist is limited in the centered position to help the vehicle track straight on the highway.
• The Heavy Duty replacement steering box is a 16:1 ratio. The benefit to you: effectively 3.5 turns from lock-to-lock compared to 4.5 turns.
• Larger internal piston diameter (80mm) for greater power assist
• Larger diameter bearings support the output/Pitman shaft

If you use a Borgeson Replacement Steering Shaft (part numbers 000950 or 000945), the steering box installation is a simple bolt-in-place operation. The Delphi box and shaft are a full-circle spline design.

This steering box will only work on trucks with 4WD. This will also work on 1994 to 2001 Ram 1500 4WD trucks.

NOTE: To use this steering box with your truck's existing steering shaft (a female, D-shaped spline design), the input shaft (male, O-shaped) will have to be filed-down with a grinding wheel.

NOTE:This steering box will work on Cab/Chassis trucks.

NOTE:This steering box is larger than the original box and will not always work with other aftermarket accessories without modification. For example, steering box braces.

NOTE: Frame spacers included.

NO CORE CHARGE. WE DO NOT NEED THE CORE BACK.

ONE YEAR WARRANTY

Rebuilt exclusively for Geno's Garage by a leading steering gear manufacturer.

************
IMPORTANT! TECHNIQUE TO PROPERLY CENTER YOUR NEW GEAR BOX
Make sure that any gear box that is installed is installed properly centered. Turn the input shaft all the way to one direction, then count turns to the full stop at the other direction. Split this number in half then turn the input shaft back to find the proper center. Once true center is found, make a paint pen mark at the top of the sector shaft that will still be visible once the pitman ram is installed, then make another line just above it on the gear box body. After the gear box is installed and the alignment completed, the lines must still line up perfectly. If not, the gear box is no longer centered and will wander on the road.

FAQs

Part No. GG-800112 - STEERING BOX - HEAVY DUTY UPGRADE - DELPHI ('94-'02, 2500/3500, 4WD)

Q: I was looking at the GG-800112 gearbox. What adapter is that on the input shaft of the box? Is there a part number I can look up?

A: The adapter is to allow the direct installation of a Borgeson 000950 or 000945 steering shaft to the Delphi steering box. If you choose to use your factory steering shaft, you will need to grind a flat side on the steering adapter to match the orientation of the flat side on the factory steering shaft.

We do not have this adapter on our website, but you can call us at 770-886-2500 and order it over the phone. This adapter costs $47.50 (price at time of this FAQ July 2025 - prices always subject to change).

***********************************
Q: I have a 1997 Dodge Ram 1500 4X4 Magnum with 318. Will either the PSC XD steering box upgrade or the Delphi heavy-duty upgrade fit this truck?

A: If your Ram 1500 is stock ride height, then the PSC (PSC-SG851) box will NOT install properly due to the size. Even with a smaller leveling kit (2-2.5 inches) you still may need to trim the short drag link rod end that drops into the pitman arm, and this is due to the much larger size of the PSC gear box. But if the truck is lifted and leveled, this gear box will install with some adjustment. The PSC box is basically a 2009 and newer gear box that was reworked to bolt directly to a 2nd Generation 1994-2002 Dodge Ram 4X4 truck. The PSC does not have any adapters, the factory hydraulic hoses, pitman arm and input shaft bolt directly to the gear box but there are spacers and new bolts included to space the gear box off the frame for proper fitment. Due to the spacers and larger footprint of the PSC gear box, this moves the gear box closer to the passenger side causing the drag link to need to be shorter.

The Delphi (GG-800112) gear box is still larger and more heavy-duty than an original Mopar box but works better on non-lifted trucks due to its smaller size than the PSC. Still, it is larger than a factory box, so smaller spacers are included. (Longer bolts are not needed nor provided). The pitman arm and hydraulic lines are direct bolt-on, but the input shaft does have an adapter to be able to install a Dodge style input shaft. The factory input shaft can be used if it is in good shape or the Borgeson aftermarket steering shaft would be a direct bolt-on with no modification needed to the adapter. If you are going to use your factory steering shaft, you will install everything properly centered and the last step would be installing the steering shaft. Slide the factory shaft down and transcribe the flat spot from the factory steering shaft to the adapter. Remove the adapter and grind a flat spot to match factory shaft. Test fit and reinstall in the same orientation as removed. Now, the factory steering shaft can be used with this box.

In general, we would suggest the PSC box for any truck with a lift and running 35 inch or larger tires. Especially if the truck does any off-roading and/or someone simply wants the biggest most heavy-duty gear box available for this year range truck.
