ATI 1JZ 2JZ Harmonic Balancer 

ATI Super Damper Harmonic Balancer suits all Toyota 1JZ & 2JZ engines, ideal for high performance and racing engines. This balancer is designed to eliminate harmful torsional crankshaft harmonics that cause horsepower loss.

At Street Race Solutions, we utilise the ATI Harmonic Balancers on every build. These kits are designed to handle higher RPM and horsepower than factory balancers and are an ideal upgrade for high performance applications.

Horsepower Rating: While ATI do not advertise a horsepower rating for this balancer, we have utilised this balancer on “STCHDUP“, a 1300HP 2JZ S15 built by SRS. If your application is greater than 1000 horsepower, please get in touch and we can assist with an alternate, custom balancer for up to 1500 horsepower.

Not sure if this balancer is right for your application? Please contact us and our team can help out!
