Product Description
LOCK DOWN YOUR POWERSTROKE’S BOTTOM END. The ARP 250-6301 Rod Bolt Kit is engineered for 2003–2010 Ford 6.0L/6.4L Powerstroke builds that demand bulletproof reliability. Manufactured from premium ARP2000 alloy and designed for consistent clamp load, these bolts help protect rods and bearings at high cylinder pressures and sustained RPM. Expect outstanding fatigue strength (around 200,000 psi tensile) and repeatable torque for confident assembly and long service life.
Ideal during stock refreshes, towing builds, and aggressive tunes, this kit replaces tired factory hardware with proven ARP quality. Pair with ARP 250-4202 6.0L head studs or step up to ARP 250-4205 625+ head studs for top-end sealing under heavy boost. Secure your rotating assembly and build with confidence — from daily duty to weekend competition.
