This engine Con‑rod is forged from high-strength alloy steel with precise heat treatment, featuring excellent tensile strength, fatigue resistance and structural rigidity. It efficiently transmits power from piston to crankshaft, ensuring smooth engine operation and stable power output. Machined by high-precision CNC equipment, it has accurate big and small end bores with perfect fitting clearance for smooth running, ideal for direct engine repair and OEM replacement. With strengthened and anti-rust surface treatment, it is high temperature resistant, wear-resistant and deformation-proof, ensuring long service life under high-speed and heavy-load conditions.
Having passed dynamic balance, tensile and fatigue durability tests, it complies with international engine standards for reliable performance.
Suitable for various passenger and commercial vehicle engines with full range of specifications, it is a premium core part for the global engine aftermarket with bulk cross-border supply available.
