Performance Connecting Rods
Forged H-Beam — AMG M177 / M178
High-strength forged connecting rods engineered for Aston Martin and Mercedes-AMG 4.0 L twin-turbo V8 platforms (M177 wet-sump / M178 dry-sump). Developed to withstand extreme cylinder pressures, torsional loads and high RPM, while maintaining precise balance across all eight rods.
Construction & materials
- Forged from 4340 aerospace-grade steel, fully machined and shot-peened.
- H-beam design for optimum strength-to-weight ratio.
- Equipped with ARP2000 bolts for extreme boost.
- Weight-optimized with end-to-end balance tolerance of ±1 g per set.
Performance advantages
- Supports significantly higher boost and power levels vs OEM rods.
- Improved bearing housing geometry for stable oil film under high load.
- Compatible with OEM and aftermarket pistons.
- Heat-treated and magnaflux-inspected for crack resistance.
Applications
- High-boost tuning and hybrid turbo upgrades.
- Forged piston builds and strokers.
- Track and hybrid powertrain projects requiring superior durability.
Note: Recommended for builds targeting elevated boost/torque. Use with matched bearings and follow OEM torque/angle procedures with ARP-spec lubrication.
