S&S CYCLE T111 Long-Block Engine 310-0830A

Upgrading from a stock engine means choosing between a tired rebuild or a purpose-built replacement—the S&S Cycle T111 Long-Block delivers measurable gains in horsepower and torque without requiring frame modifications or a complete electrical overhaul. This domestically manufactured engine combines CNC-machined B3 cylinder heads with S&S easy-start gear drive cams to provide reliable starting, reduced vibration, and extended engine life in a package that drops into your existing chassis. With a 2-year warranty backing your investment, the T111 represents a practical path to genuine performance rather than incremental improvements.
