Product Information

We at Merchant Automotive have used this product in our shop on several occasions. To ensure that the balancer is locked in position, ARP has developed these ultra strong bolts that let you increase the tensile strength up to 200,000 psi.

 

Features and Benefits

  • Low Profile 36MM 12-Point Head
  • 200,000 psi Tensile Strength Rating
  • Chrome Moly Steel Bolt with Black Oxide Finish
  • Includes 1/2 oz. pack of ARP Ultra-Torque Lubricant

As the crankshaft flexes and twists in your Duramax, the balancer absorbs incredible amounts of kinetic energy. The damper or “balancer” has counter weights and vibration dampening properties to soak up harmonics which help prevent your crankshaft from prematurely cracking.

 

This Harmonic Damper bolt by ARP features a low profile 12-Point head, 200,000 psi tensile strength rating and includes a 1/2 oz. pack of ARP Ultra-Torque fastener assembly lubricant. This excellent product is manufactured from premium grade chrome moly steel with a Black Oxide finish. 

 

To ensure proper thread engagement and accurate torque readings, clean the threads in the end of the crankshaft. Chase if necessary with a Thread Chaser or Tap. Lubricate the threads of the bolt, the under-head of the bolt and the front face of the balancer (where the washer contacts the balancer) with the provided ARP Ultra-Torque Lubricant. Once lubricant is sufficiently applied, slide the washer onto the bolt and install. Torque the  bolt to to 325 ft-lbs.
