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.
Do the Spool Mitsubishi 4G93 conrods require any modifications for installation?
Yes, these connecting rods may require clearancing of the cylinder block for proper installation. It's essential to check for any interference before final assembly.
What is the weight of the Spool Mitsubishi 4G93 conrods?
Each conrod weighs approximately 510 grams, ensuring a lightweight yet robust design suitable for performance applications.
What materials are the Spool Mitsubishi 4G93 conrods made from?
These conrods are constructed from high tensile 4340 forged steel, providing excellent strength and durability for high-performance applications.
Are the Spool Mitsubishi 4G93 conrods suitable for high horsepower builds?
Yes, customers have successfully used these conrods in builds producing over 1000 RWHP. However, reliability will depend on proper machining, clearances, tuning, and fuel quality.
Do the Spool Mitsubishi 4G93 conrods come with bearings?
No, the Spool Mitsubishi 4G93 conrods do not include bearings. You will need to source compatible bearings separately for your build.
