J.E. PISTONS FORGED SILICON ALUMUNIM PISTONS
THESE PISTONS ARE CUSTOM MANUFACTURED FOR US BY J.E. FORGED RACING PISTONS.
THESE ARE THE BEST PISTONS ON THE MARKET FOR USE IN THE BURTZ BLOCK MODEL A ENGINE!
THESE PISTONS ARE MACHINED FROM A HIGH SILICON ALUMINUM FORGING. THIS RESULTS IN A VERY STRONG & LIGHTWEIGHT PISTON WITH MINIMUM HEAT EXPANSION PROPERTIES.
THESE PISTONS HAVE THE STANDARD COMPRESSION HEIGHT, 1" PIN DIAMETER, DOUBLE SPIROLOCK PIN RETAINERS, 5/64", 5/64", 3/16" RING GROOVES FOR MODERN MOLY RING SETS.
WE ONLY OFFER THIS PISTON IN STANDARD BORE. IF YOU USE YOUR ORIGINAL MODEL A FORD BLOCK YOU MUST SLEEVE IT TO STANDARD BORE WITH OUR A-6055 SLEEVE IN ORDER TO PROVIDE THE CORRECT CYLINDER WALL MATERIAL TO BE COMPATIBLE WITH MODERN MOLY RINGS.
THIS PISTON HAS OUR TEFLON COATING ON THE SKIRT & CERAMIC COATING ON THE TOP. THESE COATINGS ALLOW FOR TIGHTER PISTON TO WALL CLEARANCES, RESULTING IN LESS PISTON ROCK. THIS HOLDS THE RINGS MORE SQUARE TO THE BORE FOR A BETTER SEAL, MORE POWER & A QUIETER RUNNING ENGINE!
