Product Details

The Mr. Gasket 7847 Harmonic Balancer Bolt is engineered for reliable installation of harmonic balancers on high-performance and street engines. This premium replacement bolt ensures proper clamping force and secure retention of your harmonic balancer, preventing potential engine damage from a loose or failed fastener.

Key Features:

  • Heat-treated Grade 8 alloy steel construction for maximum strength and durability
  • Black oxide coating provides corrosion resistance and a professional appearance
  • Includes thick, parallel-ground washer for more accurate and uniform torque application
  • Precision-engineered threads for proper engagement and reliable clamping force
  • Direct replacement for worn or damaged OEM harmonic balancer bolts

Grade 8 fasteners offer superior tensile strength compared to lower-grade hardware, making this bolt ideal for performance applications where engine vibration and stress demand the strongest possible connection. The included precision-ground washer distributes clamping load evenly, helping to prevent distortion and ensuring consistent torque readings during installation.

Great prices and items were shipped very quickly. I will definitely buy from Autoplicity again.

Very good price. Super quick delivery. Will def. buy from them again. Highley recomend them

Best price on internet. Local dealer wanted 325 dollars more for exact item. Great place to do business.

Shopped for the best price I could find on my combo pintle/tow hitch and Autoplicity came in the lowest. So I'm expecting maybe a super long delivery right? Nope they shipped it Immediately and I just got it like 3 days later. I will order again in a heartbeat. Have no fear their a great supplier
