5.670 Super Damper Honda K20 2001-2015 SFI

The ATI Performance 5.670 Super Damper Honda K20 2001-2015 SFI is a precision harmonic balancer engineered to reduce crankshaft vibration and protect your engine during high-performance driving. Designed specifically for Honda K-Series engines, this balancer absorbs damaging oscillations that occur at elevated RPMs, extending component life and improving overall reliability. Whether you're building a street performance K20 or maintaining a daily driver, this SFI-certified damper delivers the stability your engine needs to perform at its best.

Built with an aluminum hub and steel ring construction, the 5.670-inch outside diameter balancer is optimized for K-Series geometry and delivers superior damping characteristics compared to OEM units. The SFI 18.1 certification ensures compliance with racing safety standards, making it suitable for both street and competition applications. The black finish provides corrosion resistance, while the two-piece design allows the elastomer core to isolate vibration frequencies that can lead to bearing wear, seal failure, and structural fatigue on modified or high-revving engines.

K20 owners—whether running stock displacement or boost—benefit from OEM-quality damping at an accessible price point. Installation requires engine access and basic mechanical skill; the balancer is a direct replacement for K20Z, K20A, and K20Z3 applications from 2001 through 2015 model years. Weighing 6.85 lbs and measuring 9.5 x 4 x 9.6 inches, it integrates seamlessly into tight engine bays. This is the damper of choice for builders who demand reliability during dyno runs, street acceleration, and long-term durability without compromise.
