Small Block Chevy Pistons Ross Forged
Lightweight Pistons
ROSS Racing Pistons are used in high performance and
racing engines by knowledgeable engine builders the world over. They combine light weight,
high strength, precision machining and premium materials to build a piston you can depend
on for high horsepower, torque and reliability. We offer these superb pistons at very
affordable prices.
Ross Racing Pistons
offers pistons in both stocking and custom sets. In most cases you can find a stocking set
to fit your needs. If you do not see the exact piston specs you want in a stocking piston,
we will be happy to help you with a custom piston design. Custom pistons
can be made for just about any type of engine. Please e-mail us and we will be happy to assist
you with a custom piston order. We offer discounted pricing, even on custom pistons so
please contact us for assistance with your custom piston needs and we will be happy to
help you and give you a great price quote.
ROSS includes forced pin
oilers and double spirolox on all of their stocking pistons. Pistons are balanced to plus
or minus 2.5 grams throughout the set. You can buy replacement pistons one at a time as
needed. The valve pockets are designed to handle most camshaft applications. The skirt
design allows the pistons to work properly under intense heat and tremendous side loads
without scuffing or splitting cylinder walls. Most normally aspirated pistons are designed
to operate at .004 piston skirt to cylinder wall clearance. All ROSS stocking pistons
include aircraft quality pins that are heat treated and end ground to work in full floated
or press fit applications.
Please feel free to use
our compression ratio calculator to help you decide on the piston specifications you want.
