SBC Dished Piston Set 4.165 Bore -26.8ccc

The JE PISTONS SBC Dished Piston Set 4.165 Bore -26.8cc is a forged piston set designed specifically for small-block Chevy engine builds that require precise compression control and reliable high-RPM performance. This complete set of eight pistons is ideal for serious engine builders, street performance enthusiasts, and race teams focused on maximizing power output while ensuring durability in demanding conditions.

Each piston features a 4.165-inch bore diameter with a dished crown geometry that delivers a compression volume of 26.80 cc. The forged construction provides superior strength and fatigue resistance compared to cast alternatives, making them critical for engines routinely subjected to extended high-load or high-RPM operation. The 1/16 x 1/16 x 3/16-inch ring groove configuration supports standard small-block Chevy ring packages, ensuring proper ring seal and blow-by control across the engine's operating range.

These precision-forged pistons maintain tighter tolerances under thermal cycling, reducing skirt wear and extending engine life in both street and track applications. They are essential for builders balancing compression requirements with power goals in small-block Chevy applications, from classic hot rods and street machines to modern performance builds. The dished crown design is particularly suitable for combinations requiring lower compression ratios, making them versatile for various engine setups.
