What bolts do these conrods use and how should I tighten them?
These rods use ARP conrod bolts, usually ARP2000 as standard with L19 or CA625+ available on some models. ARP2000 bolts are generally torqued to around 55 ft-lb for 3/8 inch and around 75 ft-lb for 7/16 inch when using ARP Ultra-Torque lube. L19 bolts must be tightened by stretch, not torque. Always refer to the latest ARP instructions for exact specifications.
Do these conrods have a horsepower rating or warranty?
No. Like other performance rods, they do not carry a horsepower or performance warranty. Spool warrants workmanship before installation, but once fitted, power handling depends entirely on machining, clearances, tuning, fuel, boost level and rpm.
Do the big end and small end need machining?
They often do. Crank journals and pin bores vary between engines, so your builder should measure the big end oil clearance and small end pin clearance and hone as required before assembly.
What are the advantages of using ARP Custom Age +625 bolts?
ARP Custom Age +625 bolts are made from a super-alloy that offers superior tensile strength, typically between 260,000-280,000 psi. They provide exceptional fatigue cycle life and toughness, making them ideal for high-performance applications. Additionally, they are resistant to atmospheric corrosion and oxidation, ensuring long-term reliability in demanding environments.
How should I install ARP Custom Age +625 bolts in my conrods?
When installing ARP Custom Age +625 bolts, it's crucial to follow ARP's specific torque or stretch specifications. For these bolts, ensure you are using the correct installation procedure as outlined by ARP, which may include using their Ultra-Torque lubricant for accurate torque readings.
Are ARP Custom Age +625 bolts suitable for all engine types?
ARP Custom Age +625 bolts are designed for high-performance applications and can be used in various engine types. However, it's essential to consider the specific requirements of your engine build and ensure that these bolts are compatible with your conrod design and intended use.
What is the recommended maintenance for ARP Custom Age +625 bolts?
Regular inspection of ARP Custom Age +625 bolts is recommended, especially after high-stress use. Check for signs of wear or fatigue, and ensure they are properly torqued to the specifications provided by ARP. If you are disassembling the engine, consider replacing the bolts to maintain optimal performance.
Can I use ARP Custom Age +625 bolts with other brands of conrods?
While ARP Custom Age +625 bolts can be used with various conrod brands, it's crucial to verify that the bolt dimensions and specifications match the conrod design. Always consult with the conrod manufacturer to ensure compatibility and proper fitment.
