Manley has defined the standard for "Severe Duty" internals. Their Turbo Tuff® I-Beam connecting rods are forged from 4340 aircraft-quality vacuum degassed steel, featuring a unique ribbing and shot-peening process that makes them nearly indestructible in 1000hp+ environments. Complementing these are the Platinum Series pistons, forged from 2618 high-strength alloy and featuring offset wrist pins for quiet cold starts—a critical detail for high-performance street engines in the Australian climate.
Our sourcing capabilities cover the flagship Manley Performance range:
• Platinum Series Pistons: Precision-engineered forged pistons with moly-coated skirts, essential for Falcon (Barra), WRX/STI (EJ20/EJ25), and Lancer Evolution (4G63/4B11) builds.
• Turbo Tuff I-Beam Rods: The definitive "big power" rod. Designed for extreme boost and nitrous applications on the Supra (2JZ), Skyline (RB26), and Civic Type R (K20C1).
• H-Tuff Series Rods: A beefed-up H-Beam design that provides a robust, cost-effective solution for 600-800hp builds on the 86/BRZ (ZN6/ZN8) and Golf R (MK7/MK8).
• NexTek Valve Springs: Advanced valve spring kits and titanium retainers designed to allow for high-lift cams and increased RPM limits without valve float.
