What is the advantage of using ARP 625+ fasteners?

ARP 625+ fasteners are made from a special alloy that offers significantly higher tensile strength and fatigue resistance than standard rod bolts. This means they can withstand greater clamping forces and repeated stress cycles, crucial for high-performance engines.

Are these rods balanced?

Connecting rods are typically sold individually and require balancing as part of a complete engine assembly. It is recommended to have these rods weighed and balanced with your pistons, crankshaft, and other rotating components by a professional engine builder.

What does the '7 Bolt' designation mean for the 4G63 engine?

The '7 Bolt' refers to the number of main bearing cap bolts used in the earlier versions of the Mitsubishi 4G63 engine. This specific rod is designed to fit those 7-bolt engine configurations, distinguishing them from the later 6-bolt models.
