CP Piston & Ring for Chevrolet Small Block - Bore (4.040in) - Rod (5.700in) - CR (10.5:1) - Single

CP Pistons is a well-known name for building high-performance engine components, and this forged piston set is a great example of their work. This particular set is designed for Chevrolet Small Block engines, specifically for builds where you're looking for a 10.5:1 compression ratio with a 4.040-inch bore and a 5.700-inch rod length. These pistons are built to handle the demands of a performance engine.

When you're putting together a performance engine, the pistons are a critical piece. These are forged, which means they start as a solid block of aluminum that's heated and hammered into shape. This process makes them incredibly strong and durable, able to withstand higher cylinder pressures and temperatures than cast pistons. The 4.040-inch bore size is a common starting point for many popular Small Block Chevy builds, and the 5.700-inch rod length is also a standard dimension that works with many crankshafts. The 10.5:1 compression ratio is a good target for a street/strip application, offering a nice bump in power without being too aggressive for pump gas in many setups.

This is a single piston and ring set, so be sure to order the correct quantity for your engine. Please note that this part is not CARB approved and cannot be shipped to California.
