Pistons by ROSS & JMB Services

To fit DB2, DB4, DB5, DB6 & DBS Aston Martins


Here at JMB services we offer a range of custom pistons for Aston Martins DB2, DB4, DB5, DB6, DBS & V8. Our pistons are engineered to our exact specifications to give maximum performance and reliability. Forged and heat treated 26/18 Aluminium, fully CNC machined maintaining even weight and material mass distribution.

Our stringent techniques allows us to engineer a very evenly balanced set of pistons. Pistons to fit DB4, DB5, DB6, DBS & V8 have been made with slipper skirts to further reduce unnecessary weight, and are then Teflon coated on the skirt area to reduce friction and wear.

All JMB pistons are supplied with Total Seal piston rings, arguably the best there is, and chrome molybdenum gudgeon pins.
