Product Advantages
- High-strength alloy connecting rods with professional quenching & tempering heat treatment, outstanding anti-fatigue performance to resist bending or cracking under high engine load.
- Precision machined pistons with optimized ring grooves enhance cylinder sealing, effectively reduce excessive oil consumption and blue exhaust smoke.
- Low-friction bimetallic bearings maintain stable oil film and consistent oil pressure, minimize crankshaft and rod journal wear, reduce abnormal engine vibration and rough idle.
- All parts are CNC machined to OEM original dimensions for direct bolt-on replacement without modification, ideal for full bottom-end engine rebuild of GM crossover SUVs and performance sedans.
- Integrated one-stop combo saves separate parts sourcing time for repair shops and DIY engine rebuilders.
