The ARP 200-6209 is a high-performance connecting rod bolt kit featuring ARP2000 Pro Series material, designed as a general replacement solution for steel connecting rods. This 8-piece kit delivers the superior strength and reliability that has made ARP the preferred choice of connecting rod manufacturers and racers worldwide.
Why ARP Rod Bolts Are Superior:
The connecting rod bolt has always been the weak link in any connecting rod assembly. ARP rod bolts are engineered to deliver up to ten times the fatigue strength of competing fasteners, making them the gold standard for high-performance and racing applications. Each bolt is proudly stamped with the ARP name as your assurance of quality and reliability.
ARP2000 Material Advantages:
ARP2000 is an advanced alloy steel capable of achieving clamping loads at 220,000 psi, offering significantly greater strength than traditional 8740 chrome moly. This material is widely used in short track and drag racing as an upgrade in both steel and aluminum connecting rods, providing improved reliability without the extreme cost of exotic super-alloys. When properly installed, ARP2000 resists stress corrosion and hydrogen embrittlement.
Key Features:
- Forged in-house at ARP using only the finest quality materials
- Heat-treated using special vertical racks to assure complete 360-degree penetration
- Threads rolled after heat-treat to provide up to 10-times longer fatigue strength
- Precision CNC-machined to exacting specifications
- Specially designed for optimum reliability in steel rod applications
Wave-Loc Technology Benefits:
- Wave-Loc surface contacts the rod and cap for optimum alignment and reduction of fluctuating stress
- Provides snug interference fit (.001 to .005) for all OEM connecting rods despite wide factory tolerances
- Superior material grain flow compared to knurled bolts that create stress risers
- Eliminates galling and scoring through smooth contact surfaces
- Strengthens the connecting rod itself by improving load distribution
Important Maintenance Note:
It is critically important to monitor the stretch of each bolt and replace it when it has permanently elongated by .0005 inch. Regular inspection ensures continued reliability and safety in high-performance applications.
