Atomic Billet FatRod Conrods – Ford Barra & Intech 6-Cyl | 1800+HP Rated | H-Beam | CA625 Bolts | Oil Fed Pin & Crown Cooling
Description:
For extreme performance Barra and Intech builds, nothing matches the strength, innovation, and reliability of the Atomic Billet FatRod Conrods. These aren’t just tough rods — they’re the most advanced connecting rods ever developed for the Ford 6-cylinder platform. Designed from the ground up using aerospace-grade billet steel, these rods are engineered to thrive at 1800+hp, survive 8000+ RPM, and stand up to 9 tons of combustion pressure — 60 times every second.
Featuring a massive H-beam profile, CA625 high-tensile bolts, pressure-fed oiling to the wrist pin, and piston crown cooling channels, FatRods are trusted in engines running over 1130RWKW — and not one has failed since their release in 2004.
✅ Key Features:
✅ Suits Ford Barra DOHC and Intech SOHC 4.0L 6-cylinder engines
✅ Rated for 1500–2000+hp and extreme cylinder pressure
✅ H-beam design – superior strength-to-mass ratio over I-beam rods
✅ 13% wider, 14% thicker beam vs. standard billet rods
✅ CNC-machined from aerospace-grade billet steel
✅ CA625 high-strength fasteners (standard)
✅ Built-in pressure-fed wrist pin oiling – increases pin and bush life
✅ Piston crown cooling channels – detonation resistance through thermal control
✅ Supports .927" Chev-size wrist pins for aftermarket piston compatibility
✅ Big-end bore: 2.2394” | Small-end left at .866” for custom fitment
🛠️ What Makes FatRods Different?
✔️ Never had a single H-beam failure since 2004
✔️ Developed via CAD/CAM & FEA simulation to absorb massive TDC tensile loads
✔️ Survives over 8000g’s of TDC reversal force – a common conrod killer
✔️ Combustion load is only half the story — FatRods handle the violent pull of high RPM
✔️ Crown cooling & pin oiling are features only found in professional motorsport
✔️ Designed to pair with stroker cranks, turbo/nitrous setups & forged pistons
📦 What’s Included:

🔍 Development Milestones:
-
✅ 2004: First Hi-Kw H-beam Barra rod released
-
✅ 2008: First 698kW-rated conrod (Superleggera)
-
✅ 2010: First Barra rod with piston crown cooling & pressurised pin oiling
-
✅ Today: Still zero recorded H-beam failures in Atomic rod histor
Please note: Big end tunnels in #306200 and #306201 conrods are finished to 2.2394” (bottom size) and the small ends are left at .866” so final clearancing can be done by the engine builder to provide the correct clearance to suit the gudgeon pins. We do this as we have found some gudgeon pins come as a finished (Metric) size of 22.00mm (.8665”) (eg Cosworth, Mahle, etc) whereas other pins (predominately US made such as JE, etc) are finished to an Imperial measurement of .866”.
