Product Details

ARP's high-strength harmonic balancer bolt kit is engineered to withstand the extreme forces generated as the crankshaft flexes and twists during engine operation. These ultra-strong bolts are rated at 200,000 psi tensile strength, allowing you to apply maximum clamping force to keep the balancer securely locked in position.

Key Features:

  • 200,000 psi tensile strength for superior clamping force
  • Extra tall 12-point head design accepts deep sockets and prevents head stripping
  • 1/4-inch thick wide-area washer distributes load evenly
  • Manufactured from heat-treated 8740 chrome moly steel
  • Durable black oxide finish for corrosion resistance

Square Drive Design:

  • Integrated 1/2-inch square drive forged into bolt head
  • Accepts standard 1/2-inch drive ratchet or breaker bar
  • Enables easy engine rotation for assembly and timing procedures

This premium fastener solution provides the reliability and strength needed for high-performance and racing applications where harmonic balancer security is critical.

fast service and got what I ordered.

Just what I needed, somewhat hard to find seals delivered!

I received original factory parts and paid less than the bobo brand carquest, O'Reilly, autozone, and advanced auto sell. Being factory original everything simply unplugged and went Right back together! Very pleased!!! Not to mention I saved $200 on just the one item!! Yea I'll be a regular customer from now on thanks guys.

Quick and easy

I was under the impression by 24hr shipping that i would get it the next day. But, turns out that it "leaves" with in 24 hrs and can take 3-10 days to arrive. It's a little misleading, but I did receive it in 3 days, so I'm "ok" with the delivery time (that is why i gave it 4 stars). 10 days would have been an issue.

It was easy to fine what i needed. & to save me money thank you for your business. Now if all come as it should and work great I will be proud of you. Ty
