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 Isuzu G180 G200 conrods?
The Spool Isuzu G180 G200 conrods are made from high tensile 4340 forged steel, providing excellent strength and durability for performance applications.
Are the Spool Isuzu conrods suitable for high horsepower applications?
Yes, these conrods are designed to handle high horsepower applications, with customers reporting over 1000 RWHP. However, reliability will depend on proper machining, clearances, and tuning.
What are the specifications for the small end and big end of these conrods?
The small end pin size is 22mm, while the big end tunnel size is 52mm. Ensure these dimensions match your engine's requirements for proper fitment.
Do I need to perform any machining on the Spool Isuzu conrods before installation?
While the conrods are a direct fit, it's advisable to check for any necessary machining on the big end or small end to ensure proper clearances, as variations can occur.
What additional features do these conrods have for performance?
These conrods feature dowelled caps for precision alignment, are X-RAY and sonic tested, quenching and heat treated, shot peened, and 100% Magnafluxed, ensuring high quality and reliability.
