• Position: Bottom end — connecting rod cap to connecting rod

• Function: Provides precise clamp load to secure the rod big-end bearing and maintain crankshaft/rod geometry at all engine speeds

• Rod bolts are critical, high-stress fasteners that should be replaced during any bottom-end rebuild. Fatigue, prior stretching, or incorrect torque can lead to catastrophic rod failure. Replacing with OE-Match bolts ensures reliable clamping force and protects engine longevity.
