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 weight of the Spool Holden RB30 H beam conrods compared to OEM?
The Spool Holden RB30 H beam conrods weigh 598g each, while the standard OEM conrods weigh 702g. This weight reduction can contribute to improved engine response and performance.

Yes, these conrods are designed to be a direct fit for all Nissan / Holden RB30 engines, including those fitted with RB25 or RB26 heads, without any machining required.
