Product Details

The ARP 180-2502 is a high-strength harmonic balancer bolt engineered to withstand the extreme forces generated by crankshaft flex and torsional movement. Manufactured from heat-treated 8740 chrome moly steel with a 200,000 psi tensile strength rating, this bolt ensures maximum clamping force to keep your harmonic balancer securely locked in position under the most demanding conditions.

Key Features:

  • Integrated 1/2-inch square drive forged directly into the bolt head, allowing engine rotation using any standard 1/2-inch drive ratchet or breaker bar
  • Ultra-strong 8740 chrome moly steel construction with 200,000 psi tensile strength rating
  • Extra tall 12-point head designed to accept deep sockets and prevent stripping
  • 1/4-inch thick wide area washer distributes clamping load evenly
  • Heavy-duty black oxide finish for corrosion resistance

The square drive feature eliminates the need for additional tools when manually rotating the crankshaft during assembly, timing procedures, or diagnostic work. This professional-grade fastener is ideal for high-performance and racing applications where reliability and strength are non-negotiable.

Very pleased with my purchase and Autoplicity. Got the best price on the internet and received it very quickly. Product arrived just as discribed. I highly recommend Autoplicity for your on-line shopping needs.

Great so far. I'll know better once I receive and get to use it.

very good price on ebc rotors. the shipping was about avg $ and was sent fedex, amazing it got here without being damaged, but was delivered quickly. would buy from again if prices stay low

Great to deal with both online and over the phone. Buy with confidence.

I ordered new leaf springs for my Jeep Cherokee. Its already headed out to me. Ordering was nice and easy. I'll post more once i get it.

Great prices and super fast shipping. Found my new online parts store!

I was a bit concerned buying from a online retailer I had not done business with before, but Autoplicity is now on my list of preferred vendors. I was sure there would be some problem, as the part I ordered was $73 cheaper than anywhere else online (too good to be true). Well, the part arrived super fast, and was exactly as I ordered. I did not hear from them immediately after ordering, but received confirmation and tracking info when the item shipped, which was two days after ordering. All in all, a great, money saving experience.<br><br>Update:<br>While I am still pleased with the service I received, I find it odd that Autoplicity emailed me and offered me a refund of $5 for writing a review. It has been a couple of weeks since I posted my review, and I have yet to see any credits on my credit card.

I found great prices and they shipped immediately. Best deal online.
