Description

The United Engine & Machine Co SKB134.040 is a set of eight hypereutectic performance pistons designed for Small Block Chevy engines. These pistons feature a 4.040-inch bore size and 5/64 x 5/64 x 3/16 inch ring grooves, with a -7.00 cc dome volume. They are constructed from a high-silicon aluminum alloy, making them lightweight for improved throttle response and RPM changes, while remaining strong enough for high compression and temperatures.
