SPEC Steel Flywheel for 2005-2006 Volvo S40 T5 2.5L & 2004-2007 Volvo S60R 2.5L
Elevate your Volvo’s performance with the SPEC Steel Flywheel, precision-engineered for 2005-2006 Volvo S40 T5 2.5L and 2004-2007 Volvo S60R 2.5L models with stock clutch and pressure plate setups. Designed by SPEC, a trusted name in high-performance clutch and flywheel systems, this steel flywheel delivers enhanced throttle response, improved durability, and reliable power transfer for both street and track applications. Crafted to exacting standards, it ensures seamless integration with your vehicle’s drivetrain, making it the ideal choice for enthusiasts seeking performance and reliability.
Why Choose SPEC?
This flywheel is meticulously machined from high-quality steel to a .001 tolerance, ensuring a flat seating surface for the clutch and smooth rotational balance for extended engine life. Unlike lightweight aluminum flywheels, the steel construction provides a balance of performance and drivability, maintaining momentum during shifts for smoother street driving while still offering faster revs for spirited performance. It’s built to handle the demands of high-performance driving, making it a dependable choice for autocross, drag racing, or daily driving.
