BAC Steering Box Conversion Kit – Large Sector 73-82
Finally, a true 14:1 power steering box that features much better feel than OE boxes. Mopar Action and Street Legal TV have featured this kit.
Imagine, precise on-center steering without the typical wandering associated with Mopar original steering boxes. This kit is a direct bolt-in for vehicles with power steering. Our custom coupler retains the safety plunge feature of the original.
Retain your pressure and return hoses with the specific fittings provided in the kit. The box provided in this kit is the latest version featuring a one piece cast housing with integral bracketry. Available in both sector sizes to fit a large variety of Chrysler Corporation vehicles. This is the ONLY kit on the market that bolts in directly, uses factory parts and does NOT require cutting your steering column!
Pressure hose and ordering notes
Many vehicles from 1973 and newer have pressure hoses with male box side fittings. If yours threads straight into the box, choose “Add a new pressure hose” in the Pressure hose dropdown above (+$45). Not sure? Call or text us before you order and we will check it with you.
PLEASE NOTE:
- Large sector boxes were used on all C bodies and 73 and later A, B, E, F, M, J vehicles.
- Due to the higher operating pressures of the updated style steering box, a cooler is recommended*
- Vehicles with pressure hoses threaded directly into the steering box need a new pressure hose. Choose it in the Pressure hose dropdown above.
***Couplers come with a set screw on the body and the cover boot (5-0009). The standard rebuild kits will no longer be supplied due to poor parts fitment***
