EZ Electric Power Steering for your Aston Martin DB4-5-6. The Aston Martin DB4, DB5 and DB6 are beautiful cars. Aston Martin DB6 could be factory equipped with hydraulic power steering. This was not particularly technically sophisticated; it would not be out of place on a David Brown tractor. Also James Bond had a car full of hi-tech gadgets but no power steering! For all DB4 and DB5 owners and DB6 owners without power steering, or who do have power steering and want to fix oil leaks for good, EZ Power Steering has a completely new column that replaces the original one. With this, it is always possible to return the car to its original condition. Nothing can be seen of the conversion, everything is installed neatly out of sight under the dashboard and steering will be much smoother!
