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 is the benefit of the side oil squirters in the Spool CA18 H Beam Conrods?
The side oil squirters in the Spool CA18 H Beam Conrods help improve lubrication to the piston and cylinder walls, which can enhance cooling and reduce wear during high-performance applications. This feature is particularly beneficial in high-RPM and boosted setups.
Are the Spool CA18 H Beam Conrods suitable for high horsepower applications?
Yes, the Spool CA18 H Beam Conrods are designed to handle high horsepower applications, with customers reporting over 1000 RWHP. However, achieving such power levels reliably depends on proper machining, clearances, tuning, and fuel quality.
What type of steel are the Spool CA18 H Beam Conrods made from?
The Spool CA18 H Beam Conrods are made from high tensile 4340 forged steel, which provides excellent strength and durability for performance applications.
Do I need to perform any machining on the Spool CA18 H Beam Conrods before installation?
While the Spool CA18 H Beam Conrods are designed as a direct fit, it's advisable to check the big-end and small-end sizes for proper fitment. Depending on your engine's condition, you may need to hone the big-end or small-end to achieve the correct clearances.
What is the weight of the Spool CA18 H Beam Conrods?
Each Spool CA18 H Beam Conrod weighs approximately 560 grams. The rods are weight matched within ±1 gram for consistency across the set.
