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 Borgeson/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 13:1 ratio. The old box was a 16:1. 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 Borgeson box and shaft are a full-circle spline design.

This steering box will only work on trucks with 4WD. This will also work on Ram 1500 4WD trucks and Gas model 2500/3500 4WD model trucks.

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

NOTE:This steering box will not work on Cab/Chassis trucks as they use a different chassis than the pickup 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.

Incredible improvement! I couldn't be happier with this purchase. Installed Borgeson shaft also and changed all the hoses. Night and day difference.

Same as the other guy had on there few years and maybe at most 15,000 miles

output shaft is leaking after only 50k miles, 8years. Doesn't seem right
Owner Response:David, we are very sorry you had problems with this part. As you note, you've had it since 2014. Although uncommon, a leaking seal can happen on any gear box. Give us a call if you would like some assistance locating a replacement sector seal. Ask for Scott Sinkinson. Thank you for your business, David.

Only had this unit in place for a couple days now but it's definitely a noticeable upgrade... Right out of the box I was impressed. Sloppy response is gone. I actually had to learn how my Y2K Cummins tracks on the pavement again as if it was new. Buy it!!!! You'll never regret this purchase. Be patient with the pitman arm.... It's a bear. Use the right tools. JS

Night and day difference, changed my box 4 times with O'Rielys boxes. Every single time there was a problem. Last one had 4" of play and all of them were super hard to turn. Tried the dual stabliizer shocks, steering box brace, and no luck. Changed this one, took all the rest of the BS off, (Took 6 hours with cleanup), added the borgeson shaft, and seriously there was a night and day difference. Don't read anymore just bite the box, and buy it. You won't be let down.
