What is included in a typical Spool engine kit?
Kits usually include pistons, rings, rods, bearings and related hardware depending on the engine family. Check the listing for exact inclusions.
Do I still need machining with a full engine kit?
Yes. The block must be honed and all clearances checked and set by your builder. Assembly should only occur after full measurement and verification.
What compression ratios are available for the CP pistons in the SPL-RB30SOHC-DP kit?
The CP pistons in the SPL-RB30SOHC-DP kit are available in compression ratios of 8.5:1 and 9.0:1. Choose the ratio that best suits your performance goals and tuning setup.
What are the benefits of the upgraded ARP2000 bolts used in the Spool Drag Pro conrods?
The upgraded ARP2000 7/16 bolts provide increased strength around the fasteners, enhancing the overall durability and reliability of the conrods under high-stress conditions typical in performance applications.
Do the conrods require any specific machining before installation?
Yes, the conrods may require big-end or small-end honing to ensure proper fitment due to factory journal and pin size variations. Always check clearances as per your engine builder's specifications.

The double pin oilers in the CP pistons are designed to force-feed oil from the oil ring groove to the wrist pins, ensuring better lubrication and cooling, which is crucial for high-performance applications.
