Probe SRS Forged Pistons are designed for performance and race applications where a strong, lightweight forged
piston is an advantage. With hundreds of part numbers available for popular Chevrolet, Ford, Chrysler, and Honda
applications, these full-featured pistons are extremely popular for use in street and most racing combinations.
    •        Forged of 2618 t-61 Aluminum alloy for the ultimate strength and fatigue resistance.
    •        Light weight forging designs for quick revs and power.
    •        Tight piston to wall clearance design for better ring seal.
    •        Fully CNC machined domes and valve reliefs for perfect fit.
    •        Radial Anti Detonation Grooves reduce detonation by clipping pressure spikes.
    •        Pressure Equalization Channel enhances ring seal, making more power and increasing fuel economy.
    •        Full floated lightweight wrist pins and double spiro locks for durability.
    •        Narrow piston rings for the ultimate in power.
Probe FPS Forged Pistons are designed for heavy duty and high performance use when the application requires a
piston that is stronger than a Cast or Hypereutectic Cast Piston. Compression Ratios are similar to factory applications and
weights are generally lighter than the TRW equivalent. The FPS series is manufactured using the same ultra-modern
machining techniques as the SRS and PRS series pistons.

    •        Forged of VMS-75 High Silicon Aluminum for lasting performance.
    •        Light weight forging design is typically about 70 grams lighter than TRW’s.
    •        CNC Diamond machined skirts and ring grooves for increase power.
    •        Tight piston to wall clearance design for better ring seal.
    •        Reinforced piston skirts to eliminate piston skirt collapse.
    •        Radial Anti Detonation Grooves reduce detonation by clipping pressure spikes.
    •        Pressure Equalization Channel enhances ring seal, making more power and increasing fuel economy.
    •        Increased valve relief depth for high performance camshafts.
    •        Offset wrist pins for reduced noise and lasting operation.
    •        Stock size rings grooves and press fit piston pins.
Probe PRS Forged Pistons are specifically designed for racing applications. Now available for the Chevrolet 350 and
Ford 2300, Probe PRS pistons are designed to be the lightest pistons available anywhere. In addition to the ultralight
weight Probe PRS forged pistons are designed to radically reduce drag and enhance ring seal to increase power.

The Probe Industries revolutionary "Monocoque" 2618 forging produces the first true ultralight piston designed specifically
for Chevrolet 2 barrel oval track use. A piston designed for a 355 cubic inch engine with a 6.000 inch center to center
connecting rods currently weighs a mere 362 grams. This incredibly low weight is achieved with NO INTERNAL MILLING!   
Due to the exclusive "Monocoque" forging design the Probe PRS forged piston is also stronger than any piston in it's class.
This Probe piston forging virtually eliminates "oil canning" the piston deck, allowing a thinner deck with superior strength.

Added to the unequalled piston acceleration gained with the ultralight design, is the "frictionless" piston technology. The
Probe PRS forged piston comes fully equipped with .043 .043 3.0mm ring grooves, allowing the use of extremely low drag
piston rings. The specially designed skirt substantially increases available power and reliability. Excellent ring seal is
ensured with the standard lateral gas ports in the top ring. Dual forced pin oilers are standard. And overall reciprocating
weight is further reduced by the use of a .927 x 2.250 wrist pin.

    •       Forged of 2618 t-61 Aluminum alloy for the ultimate strength and fatigue resistance
    •       Light weight "Monocoque" forging designs for quick revs and power
    •       Lateral gas ports for the ultimate in ring seal
    •       Narrow ring lands .043" top and second in most models
    •       "Frictionless" skirt designs
    •       Radial Anti Detonation Grooves reduce detonation by clipping pressure spikes
    •       Pressure Equalization Channel enhances ring seal, making more power and increasing fuel economy
    •       Lightweight 2.250 pins and double spiro locks for durability.
Probe - Advanced CNC Manufacturing
Advances in CNC machine capability and the utilization of a "clean sheet of paper" method of manufacturing design has allowed
Probe to create a piston line that is arguably a work of art. Our method of machining wrist pin bores provides the most accurate pin
bore imaginable. At nominal clearance a wrist pin can be dropped through the piston with virtually no resistance, the result of
eliminating the honing operation.

Probe Forged Pistons also feature the latest design innovations in ring land technology.  The top ring land features radial anti
detonation grooves. These grooves knock the peaks off shock waves within the cylinder, reducing the propensity to detonate.  The
second ring land features our pressure equalization channel, which is a shaped channel that works by equalizing the pressure
seen between the top and second ring with the pressure in the combustion chamber. This feature enhances ring seal, improving
power, engine life and fuel economy.

In the past all pistons featured cam ground piston skirts to achieve the shape required to work in an engine. As with most things
computer technology has provided us with the ability to improve upon this technique. Probe Racing Components is the recipient
the newest CNC technology available to achieve the most accurate piston skirt designs and finishes in the industry. Further a
complete "rethink" of the tooling and fixtures have allowed us to eliminate the variations caused by multiple setups.

Probe Forged Pistons provide you with quality and features normally found only in pistons costing substantially more. Further they
are in stock ready for immediate delivery.
