    Supertech Forged Connecting Rods

    Built to Endure. Designed to Perform.

    Supertech connecting rods are engineered for the demands of modern performance engines. Manufactured from premium 4340 forged steel alloy, each rod is optimized using CAD and Finite Element Analysis (FEA) to achieve superior balance, fatigue resistance, and strength-to-weight ratio. Whether you’re building a high-boost turbo engine or a naturally aspirated race motor, Supertech rods deliver reliability at every RPM.

    Precision Manufacturing & Engineering

    • Forged 4340 Alloy Steel – heat-treated and shot-peened for maximum strength and fatigue life.
    • H-Beam and I-Beam Designs – optimized for specific power levels and engine characteristics.
    • In-House CAD & FEA Design – ensures ideal geometry, stress distribution, and consistent performance.
    • Precision CNC Machining – guarantees dimensional accuracy and perfect bearing alignment.
    • Rated up to 250 HP per Cylinder – depending on ARP fastener selection.

    H-Beam Connecting Rods

    Supertech’s H-Beam Connecting Rods combine low weight and high strength for exceptional high-RPM stability. Each rod set is balanced to tight tolerances for smooth performance under extreme boost or compression loads.

    • Made from 4340 forged steel with heat treatment and shot peening.
    • Comes standard with ARP 2000 bolts (220,000 psi clamp load).
    • Optional ARP 625+ bolts rated up to 280,000 psi for extreme power builds.
    • Typical weights: 520–550g per rod, depending on application.
    • Ideal for turbocharged, supercharged, or endurance race engines.

    I-Beam Connecting Rods

    The I-Beam series offers additional rigidity and stiffness for high-compression or boosted setups where maximum structural integrity is essential. The robust beam profile minimizes flex under load while maintaining precise crank-to-piston alignment.

    • Forged from 4340 steel with tapered beams for weight reduction.
    • Available with ARP 2000 or ARP 625+ fasteners.
    • Machined for high flow and oiling efficiency in endurance or track conditions.
    • Balanced in sets to ±1g tolerance.

    Popular Applications

    Supertech connecting rods are available for popular engines including Honda K-Series, Toyota B58 / 4U-GSE, Subaru FA20, Nissan SR, BMW B48 / 54 , and VW/Audi 1.8T / EA113.

    Designed for OEM fitment with race-grade performance, each kit includes matched rods, precision hardware, and installation-ready specifications.
