Summit Racing LS Harmonic Balancers

From Trucks to Firebirds, Summit Racing has your GM LS engine covered for replacement harmonic balancers. These balancers are 18.1 SFI rated to keep you legal at the track and are made of carbon steel which is stronger than the nodular iron ones that come stock. Summit Racing spin tests the harmonic balancer to 12000 RPM so it can handle the revs you are going to throw at it. Summit Racing harmonic balancers also include timing marks engraved on the balancer so you can adjust your timing for your performance application. http://www.summitracing.com/search/pr...
