Suitable
for Heavy Duty, high performance street and some race applications!
Probe FRS 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.

Specifically
designed for racing applications!
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 3mm 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.
