There are two possible part numbers for the Durango Steering box.
- Recommended: #277580 - 98 Durango V8 with the snow plow option has the 3.5 turns lock to lock. Some have received them with only 3 turns.
- #277588 (non-plow option only has 3 turns lock to lock at 2 15/16) per
- Atsco 7561
Cons with Durango boxes
- Never know if you get the 3 turn vs 3.5 turn lock to lock
- The sector shaft bearing support sucks and may get lateral play. Doesn't use ball bearings
- Power Steering Pump may need to be swapped with a PSC or WJ V8 steering pump to account for volume increase.
