ARP V8 Rod Bolt Kit - S62 - E39, E52

Product Details

The BMW S62 is a legendary, high-revving naturally aspirated V8, but its factory connecting rod bolts are a notorious weak point when pushed past the stock redline or subjected to the rigors of endurance racing. Sustained high RPMs exert massive inertial forces on the rod caps, leading to fastener stretch and catastrophic bearing failure.

The ARP Pro Series Rod Bolt Kit is the ultimate insurance policy for the S62 bottom end. Engineered specifically to handle the extreme tensile loads of motorsport environments, this kit provides the precise clamping force needed to keep your rod bearings perfectly round and secure under high-load, high-RPM conditions.

Key Features & Technical Specifications

• Premium Material: Forged from proprietary ARP2000® alloy, delivering a level of fatigue life that far exceeds standard chromoly steels.

• Tensile Strength: Rated at an incredible 220,000 psi, ensuring maximum resistance to stretch and deformation at high RPMs.

• Thread Integrity: Threads are rolled after heat treatment, which increases fatigue resistance by up to 1000% compared to fasteners threaded before heat treat.

• Precision Geometry: Optimally designed to fit the factory S62 connecting rods without requiring complex machining, maintaining perfect cap alignment.

• Reusable Engineering: Unlike factory Torque-to-Yield (TTY) stretch bolts which are single-use items, these ARP fasteners are fully reusable, making them essential for race teams who conduct routine engine teardowns and inspections.
