Product Details

Supertech Performance P4-H81-P6 Supertech Pistons

Supertech Pistons are manufactured from extruded high silicone, enhanced 4032 alloy (with additional Cu, Ni & Mg) that had low thermal expansion, excellent wear resistance and higher thermal conductivity. Supertech Pistons, with this alloy, have withstood up to 42psi of boost, with alcohol, without any problems.

A two or three step forging process yields a fine structural grain which are then submitted to several machining steps in state of the art CNC machines.

Several heat treatments provide the piston with high tensile strength and evenly distributed hardness.

Contact reduction grooves are standard, and pin bores are honed and reamed for precise fit. Wrist pins are constructed of cold extruded chrome moly steel for high strength and used with wire clip locks.

Finally, the pistons receive a phosphate dry lubricant coating to protect the rings against micro-welding and enhance lubrication on the skirt/cylinder area.

Compression ratios are computed with .030 head gasket and .010 deck unless indicated in each case.

Supertech Pistons are sold Per Piston. For Example, when order for a 4 Cylinder Model, order Quantity: 4

shipment came on time, and was nicely wrapped.

I wanted to pay with PayPal and it was blocked! Not a nice move!

Very nice people very considerate and helpful plus the price was nice

I found Autoplicity on a well known online vendor and the experiance was excellent so now I just go straight to autoplicity.com directly my last order (17805) was for some parts for my very modifide Jeep and two things stood out, the price and shipping, both were top shelf and above my expectations. Now when I need parts I check autoplicity.com first. They are my #1 now.<br>

Return customer with a few more future purchases in mind...best price plus quick shipping means these guys are just that good!

Very smooth ordering and processing. Great communications.
