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 recommended machining for the Spool RB20 conrods?
While the Spool RB20 conrods are designed as a direct fit, it's advisable to check the big-end and small-end dimensions for proper fitment. Depending on your specific engine, honing may be required to achieve the correct clearances for the crankshaft and piston pins.
What is the weight of the Spool RB20 conrods?
Each Spool RB20 conrod weighs approximately 488 grams. This weight is consistent across the matched sets, ensuring balanced performance in your engine build.
Are bearings included with the Spool RB20 conrods?
No, the Spool RB20 conrods do not come with bearings included. You will need to source the appropriate bearings separately to complete your engine assembly.
What materials are used in the construction of the Spool RB20 conrods?
The Spool RB20 conrods are made from high tensile 4340 forged steel, providing excellent strength and durability. They undergo processes such as quenching, heat treatment, and shot peening to enhance their performance characteristics.
Can the Spool RB20 conrods handle high horsepower applications?
Yes, the Spool RB20 conrods are capable of handling high horsepower applications, with some customers reporting over 1000 RWHP. However, reliability at these power levels depends on proper machining, clearances, tuning, and fuel quality.
