Factory Performance Series Pistons
Chevy

These pistons are direct replacements for TRW
But with additional fantastic features and at the same Low Cost!

Up to 70 grams lighter than TRW and .030 deeper valve relief's for increase cam clearance!
 




Precision Forged of Aircraft Alloy Aluminum
    
Our forgings are approximately 75% stronger than cast or hypereutectic pistons!
CNC Diamond Skirt Finishing
     Retains oil on the piston skirt providing superior anti-scuffing capability!
     Also reduces piston noise!
Stronger Piston Skirts
     "Clean Sheet" design of forgings allows for redesign of the oil return system,
     dramatically increasing the strength of the piston skirt, greatly reducing the
     possibility of collapsed piston skirts.
Ultra Tight Running Clearance
     Increase piston and piston ring life and reduces blowby!
Press Fit Piston Pins
     Provides ease of installation!
Symmetrical Valve Reliefs
     4 valve reliefs per piston simplifies installation!
Deeper Valve Reliefs
     Provides more room for high lift camshafts.  No more flycutting your pistons!
Offset Wrist Pins
     Reduces noise!  Increase piston skirt and block life.
Anti Detonation Grooves (top land)!
     Reduces detonation by tempering pressure spikes, enhances piston ring life.
Pressure Equalization Channel (second land)
     Enhanced ring seal, producing more power and enhancing fuel economy.
