SPX-SPI Piston kits (OEM Replacement)

Machined Smooth Heads:

A machined smooth piston crown should reflect combustion heat while reducing carbon buildup and protecting the top of the piston.  Some tests have shown that a machined smooth head can increase HP and fuel economy by up to 6%.

Hard Anodized Crowns:

Pistons that are not anodized have a hardness of HRB 80, and pistons that are anodized have a hardness of HRB 105.  This makes our pistons 75% stronger than non-anodized pistons.

Increases heat resistance
Minimizes piston expansion & contraction
Reduces the coefficient of friction

MOS2 (Reflon-Molybdenum Coating):

MOS2 is composed of sub-micron sized particles of solid lubricant and resin blends of solvents.  Our coating is rolled on, so it provides 10 times the bond strength of spray on coatings.

Draws heat through piston walls and out the bottom
Reduces heat and friction, for added power and longevity
Helps eliminate cold seizures, and increases durability

HyperEutectic Cast:

A hypereutectic cast piston, is a piston with increased silicon content.  The end result is a piston that has an increased hardness, is more resistant to wear, and has an increased ability to withstand higher cylinder temperatures, pressure, and detonation.

Helps reduce expansion from heat
Makes the pistons more durable and resistant to wear
Allows the piston to run tighter clearances
