Our #90010 is a 6" internally balanced Small Block Chevy harmonic balancer. This is our smallest (6" OD x .75" thick) damper for small block Chevy. This model weighs 5.7 pounds and keep in mind that the inertia ring weight is what performs the actual damping of the rotating assembly. A lightweight damper like this will not achieve the degree of damping that heavier dampers do but many racers or performance enthusiasts want the lightest damper they can get that will still do the job.

• 60 timing marks plus engraved marks every 90 degrees.
• Meets SFI#18 specs. 
• Material: 1045 Steel (Lightweight)
