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 material used for the Spool TB48 conrods?
The Spool TB48 conrods are made from high tensile 4340 forged steel, ensuring strength and durability for high-performance applications.
Are the Spool TB48 conrods a direct fit for all TB48 engines?
Yes, these conrods are designed as a direct fit for all Nissan Patrol TB48 engines, making installation straightforward for builders.
What machining considerations should I be aware of when using these conrods?
While the Spool TB48 conrods are designed for direct fit, it's advisable to check the big-end and small-end clearances. Depending on your specific engine, honing may be required to achieve the correct fit.
What testing and quality assurance processes do these conrods undergo?
The Spool TB48 conrods are X-RAY and sonic tested, shot peened, and 100% Magnafluxed to ensure structural integrity and reliability under high-stress conditions.
What is the weight of the Spool TB48 conrods?
Each Spool TB48 conrod weighs approximately 1006 grams, including the ARP2000 bolts.
