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.
