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 are the specific machining requirements for the SCR9375 conrods?
The SCR9375 conrods may require honing of the big-end or small-end to achieve the correct clearances due to variations in factory journal and pin sizes. It's essential to measure and confirm these dimensions before installation.
What is the recommended application for the SCR9375 conrods?
The SCR9375 conrods are designed for high-performance applications in the GM Ecotec 2.0L LTG engine. They are suitable for both street and racing use, providing a strong and lightweight option for builds aiming for increased power and reliability.
What is the weight of the SCR9375 conrods, and how does it affect performance?
The SCR9375 conrods have a total weight of 615 grams, with a rotating weight of 422 grams and a reciprocating weight of 193 grams. The lightweight design contributes to reduced inertia, allowing for quicker engine response and higher RPM capabilities, which is beneficial for performance applications.
Are there any special considerations for installing the SCR9375 conrods?
When installing the SCR9375 conrods, ensure that the correct ARP fasteners are used and follow the manufacturer's torque specifications. Additionally, check that the conrods are properly aligned and that the big-end and small-end clearances are within the recommended tolerances for optimal performance.
What type of fasteners are included with the SCR9375 conrods?
The SCR9375 conrods come with 3/8-inch ARP2000 bolts as standard. These bolts are designed for high strength and reliability, making them suitable for performance applications. Always refer to ARP's latest instructions for proper installation and torque specifications.
