Code produit 559M05750
Producteur: WISECO
The WISECO pistons, built in the USA, are produced by forging, do not have centesimal surcharges and their size indicated & eacute; the nominal one (i.e. referred to the nominal size of the cylinder).
This particular feature & eacute; a typicality; of Wiseco pistons, developed and used in its 70 years of production.
Wiseco forged pistons have in fact a different, but calculated, expansion compared to any other competing product that allows you to profitably use a single size in a new or moderately worn cylinder.
There & ograve; & eacute; possible thanks to the uniqueness; of the characteristics of the aluminum alloy used, to the advanced study of the expansion, therefore of the thicknesses in each precise point of the piston and to the particular forging system.
In fact, using a piston A - B - C on a cylinder that is too worn or ovalized & eacute; moreover, too precise A - B - C couplings are often used which, by increasing friction, actually reduce engine performance.
Wiseco pistons have proven over time as the best compromise between durability and performance.
