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 recommended fitment for the Spool Mitsubishi 4G63 H-Beam Conrods?
These conrods are designed as a direct fit for most Mitsubishi EVO 4G63 engines. Ensure your engine has the following specifications: 150mm centre-to-centre length, 22mm pin diameter, and 48mm big-end tunnel.
What materials and processes are used in the construction of these conrods?
The Spool 4G63 H-Beam Conrods are made from high tensile 4340 forged steel, featuring a two-piece forging design. They undergo rigorous testing including X-ray, sonic testing, and are heat treated for strength, shot peened for durability, and Magnafluxed for integrity.
Are bearings included with the Spool 4G63 H-Beam Conrods?
No, the Spool Mitsubishi 4G63 H-Beam Conrods do not come with bearings. You will need to source compatible bearings separately for your build.
What kind of power levels can these conrods handle?
While specific power ratings can vary, customers have successfully used these conrods in builds exceeding 1000 RWHP. Reliability at high power levels will depend on proper machining, clearances, tuning, and fuel quality.
Do I need to perform any machining on these conrods before installation?
Depending on your engine's specific tolerances, you may need to hone the big-end or small-end of the conrods for proper fitment. Always check clearances as per your engine builder's recommendations.
