ARP 201-6306 High-Performance Connecting Rod Bolt Kit

The ARP 201-6306 is a high-performance connecting rod bolt kit engineered by Automotive Racing Products (ARP), the industry leader in precision fastener technology. Manufactured from premium 8740 chromoly steel, these rod bolts deliver significantly greater clamping force and fatigue resistance than OEM hardware, making them an essential upgrade for performance engine builds.

ARP rod bolts are precision centerless-ground and feature rolled threads for superior fatigue resistance. The controlled thread form ensures uniform clamping load across all fasteners, reducing the risk of rod cap fretting and catastrophic engine failure under high-RPM or high-load conditions.

Key Features:

• Material: Premium 8740 chromoly steel for exceptional strength and durability
• Tensile strength: Rated up to 180,000+ psi — far exceeding OEM specifications
• Thread-rolled after heat treatment for maximum fatigue life
• Precision centerless-ground body for accurate stretch measurement
• Black oxide finish for corrosion resistance
• Includes hardened parallel washers for uniform load distribution and accurate torque readings
• Reusable — can be reinstalled multiple times when within spec

For best results, ARP recommends using ARP Ultra-Torque Fastener Assembly Lubricant during installation to minimize preload scatter and ensure consistent clamping force. Always follow the torque specifications provided in the instruction sheet included with the kit.
