1) FORGED

All Wiseco Pistons are

forged

from high silicon, low expansion aluminum which offers superior

strength, reduced weight, improved heat transfer, and longer life.

2) ADVANCED MANUFACTURING TECHNIQUES

Diamond turned finish from one of the many CNC computer controlled turning centers

guarantees you a perfect finish with no size variation. Wiseco pistons can be installed in any

of today’s cylinder bore compositions (cast iron, chrome, nikasil and boron composite) with

confidence.

3) OVERSIZE OPTIONS

Wiseco’s wide range of oversize pistons increase the life of cast iron lined cylinders.

With the availability of replacement cylinder sleeves, chrome, nikasil and boron composite

cylinders can be resleeved to accept Wiseco’s oversizes.

4) COMPUTERIZED

Wiseco’s state-of-the-art computerized manufacturing facility is dedicated to supplying both

the high-perfomance racer and recreational enthusiast with the finest forged piston available in

today’s market place.

5) EASY AVAILABILITY

Three WPS warehouses offer you one of the largest Wiseco inventories available. Our telephone

sales staff can verify availability at the time of your order. Pistons that we don’t have in stock

are rushed in air freight and are available for shipment to you within two to three working days if

Wiseco has it in stock.
