SBC Domed Piston Set 4.060 Bore +13.7cc

The SBC Domed Piston Set 4.060 Bore +13.7cc from JE PISTONS is designed for builders of small-block Chevrolet engines who are looking to enhance compression and power. This piston set is suitable for various applications, including street performance, bracket racing, and vintage muscle car restorations. Its advanced design caters to the needs of high-output engine builds.

Featuring a domed crown design, this piston set increases the compression ratio, making it ideal for naturally aspirated engines that utilize premium fuel or mild forced induction. The precision-forged construction ensures exceptional strength, thermal stability, and durability under high loads. The +13.7cc dome volume enhances static compression without the need for block machining, simplifying the installation process.

This piston set is particularly beneficial for SBC builders looking to upgrade from cast OEM units or improve compression in stroked or bored applications. The advanced skirt design minimizes friction and piston rock, which helps extend the life of the rings even under aggressive conditions. Proper installation requires attention to ring end-gap clearancing and piston-to-valve clearance verification.
