ARP 201-6302 Connecting Rod Bolt Kit Pro Series - ARP2000

The ARP 201-6302 is a complete connecting rod bolt kit featuring ARP2000 Pro Series fasteners designed to deliver superior strength and reliability in high-performance engine applications. ARP has established itself as the industry leader in connecting rod bolts, with many rod manufacturers choosing ARP bolts as standard equipment due to their unmatched quality and fatigue resistance.

ARP2000 Material Advantage:

This kit utilizes ARP2000 alloy steel, an advanced material capable of achieving clamping loads at 220,000 psi. ARP2000 offers significantly higher strength than traditional 8740 chrome moly while maintaining excellent resistance to stress corrosion and hydrogen embrittlement when properly installed. This makes it an ideal upgrade for short track and drag racing applications in both steel and aluminum connecting rods.

Superior Fatigue Strength:

Testing has demonstrated that ARP rod bolts deliver ten times the fatigue strength of competing fasteners. This exceptional durability is achieved through ARP's proprietary manufacturing process, which includes rolling threads after heat treatment to maximize fatigue life and resistance to failure.

Manufacturing Excellence:

• Forged in-house using premium quality materials
• Heat-treated using special vertical racks for complete 360-degree penetration
• Threads rolled after heat-treat for up to 10 times longer fatigue strength
• Precision CNC-machined to exacting specifications
• Each bolt proudly stamped with the ARP name as assurance of quality

Wave-Loc Technology (Where Applicable):

• Optimizes alignment between rod and cap while reducing fluctuating stress
• Provides interference fit of .001 to .005 inches for snug installation
• Superior material grain flow compared to knurled bolts
• Eliminates galling and scoring through smooth contact surface
• Accommodates wide range of factory rod bolt hole tolerances

Important Maintenance Note:

Monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inches to maintain optimal performance and safety. This complete kit includes all necessary fasteners for a professional connecting rod rebuild.
