With today’s bolt-on upgrades Diesel enthusiasts are ever increasing the horsepower and torque outputs of their engines. However many diesel owners are not aware that the stock O.E.M pistons can become the “weak link”. With the increase in boost pressure and fuel timing the stock top ring land can fracture and break, usually with serious results.

Spool Imports new ROSS Racing Diesel Power pistons are CNC-Machined out of tough 2618 T-61 forged aluminium. Featuring a full Anodized coating to increase pistons skirt life and the option of upgraded H13 gudgeon pins. These pistons are the “go to” for reliable big boost diesel high performance engines. These pistons are lighter and stronger than O.E.M pistons and can withstand more boost and RPM without failure.

Note: These pistons are designed for performance / motorsport / racing use only and are not intended as a general replacement piston for high kilometre usage.
