Product Details

The ARP 134-2501 harmonic balancer bolt is engineered specifically for Chevrolet small block engines, providing superior clamping force and reliability compared to OEM fasteners. This precision-manufactured bolt features ARP's proprietary heat-treated, chrome moly steel construction for exceptional strength and durability under extreme conditions.

Specifications:

  • Thread size: 3/4 inch - 16 threads per inch
  • Under head length: 1.300 inches
  • Socket size: 5/8 inch hex head
  • Material: Chrome moly steel with black oxide finish
  • Application: Chevrolet small block V8 engines

ARP balancer bolts are designed to prevent harmonic balancer walk and potential engine damage caused by inadequate clamping force. Each bolt is precision roll-threaded after heat treatment to create stronger threads that resist stripping and galling. The bolt includes ARP's premium parallel ground washers to ensure even load distribution and proper torque values.

Installation Note: Use ARP Ultra-Torque fastener assembly lubricant and follow ARP's torque specifications for optimal performance and longevity.
