14:1 power steering that bolts in. No cutting your column.
Imagine precise on-center steering without the typical wandering associated with Mopar original steering boxes. The Bergman steering box upgrade puts a modern Borgeson 14:1 box, our no-cut plunge coupler and factory-style Mopar parts on your car.
Why your Mopar wanders, and how the swap fixes it
Factory Mopar boxes are slow and vague, so the car wanders and needs constant correction. This box tightens everything up.
The stock steering box
- Slow and vague, so the car wanders on the highway and needs constant correction.
- The typical wandering associated with Mopar original steering boxes, instead of a precise on-center feel.
- Other conversions make you cut the column, swap hoses or bolt on parts that look out of place under the hood.
The BAC steering box upgrade
- A true 14:1 Borgeson box: about 3.5 turns lock to lock according to the manufacturer, and the steering stays centered and precise at speed.
- A direct bolt-in. Our custom coupler retains the safety plunge feature of the original, so there is no cutting your steering column.
- The latest box design, with a one piece cast housing and integral bracketry. It is lighter than the original Chrysler box and offers more exhaust clearance.
- Bolts to the stock K-frame and uses the factory pitman arm, so the swap is also reversible.

What it feels like on the road
“This steering kit is by far the best upgrade I have done to my 71 Challenger vert. The car steers and handles great. 80 mph and straight no wandering at all. Great product and customer service.”
Ricky B“Hey Peter, I purchased a borgeson steering box kit from you in June for my 68 Charger. Just got to drive my car down the road last night. Steers and drives awesome!! Thank you!!”
Chet B“It was easy to install, however I did have some questions and did reach out to you for assistance a couple of times. … It has been almost two years and everything is still working perfectly, and I love having less steering effort and the quicker steering response. Using your steering column adapter, I did not have to modify my original steering column which was a plus.”
Terry R“Finally installed the steering box and got the car aligned
Drove the car around town and highways……I should have done the swap long time ago!!
Now the car is great and more fun to drive!”

Before you order
Do I have to cut or modify my steering column?
No. Our no-cut plunge coupler connects the Borgeson box to your original column and keeps its safety plunge.
My car has manual steering. Which kit?
The Master Kit. It includes the pump, bracket, pulleys, belt and hoses as well as the box and coupler.
Small sector or large sector?
Small sector boxes were used on 1972 and earlier vehicles, except C-bodies, and have a 1-1/8″ sector shaft. Large sector boxes were used on all C-bodies and on 1973 and later A, B, E, F, M and J vehicles, with a 1-1/4″ sector shaft. Not sure? Measure the sector shaft or text us a photo.
Will it fit my engine?
The Master Kit fits LA small blocks and big blocks with little exception. For pre-1970 cast iron water pump small blocks and Gen 2 Hemi applications, email p.bergman@bergmanautocraft.com, text or call 516-384-6438 first. A Bodies with sandwich-style K-frame mounts (pre-73) need our low profile pressure hose kit, which is included when you choose that option ($1,374).
Do I need a cooler?
Recommended. Due to the higher operating pressures of the updated style steering box, we recommend adding the BAC Power Steering Oil Cooler.
