The Competition Clutch lightweight steel flywheel is made for the 2002-2006 Nissan Altima 2.5L / Sentra QR25DE. It is machined from one-piece 4140 forged steel and cuts rotating mass, so the engine revs and responds to the throttle faster than with a heavier factory flywheel.
Constructed from one-piece 4140 forged steel, these flywheels are designed to reduce rotating mass while maintaining the low-end torque and street manners needed for everyday driving. The result is improved engine responsiveness without sacrificing the durability and drivability expected from a street-performance vehicle. With application-specific weights typically ranging from 8 to 18 pounds, these flywheels offer a variety of options for different performance needs. They are an excellent choice for daily-driven vehicles, spirited street cars, and naturally aspirated performance builds, and are compatible with a wide range of performance clutch applications.
Features
- • 4140 Forged Steel • One-piece Design • Faster engine response
