Ford Focus RS Mk2 & ST 2.5 20v Turbo Forged Piston Set 8.5:1

£582.50 exc. VAT    £699.00 inc. VAT   

Designed in the UK and manufactured by Supertech. These piston sets are the end product of continued customer feedback and piston manufacturing evolution.

Supertech pistons are manufactured from extruded high silicon, enhanced 4032 alloy (with additional Cu, Ni & Mg) that has low thermal expansion, excellent wear resistance and higher thermal conductivity.

A 2 or 3 forging steps process yields a fine structural grain oriented in fibres in the same direction of the stresses.

Several heat treatments provide the piston with a high tensile strength and evenly distributed hardness. The pistons are submitted to several machining steps in specially designed machines and in conventional CNC machines with custom diamond tools for dimensional precision, perpendicularity and flatness of the ring grooves. Contact reduction grooves are standard. Honed & reamed pin bores for precise fit.
Gudgeon pins are constructed of cold extruded chrome moly steel for high strength and provided with wire clip locks.

Finally the "phosphate dry lubricant" coating is applied to protect the rings against "micro welding" and enhance lubrication on the skirt/cylinder area.

Included in the Box:-

  • Forged Pistons
  • Piston Ring Set
  • Matched Piston Pins
