All kits come with pistons, rings and
circlips. Wrist Pin is included when noted.
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 in the west. 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.
