Why Choose Forged Connecting Rods
Maximum Fatigue Life
Forged grain flow aligned with con-rod stress paths dramatically extends fatigue life.
Superior Strength-to-Weight
Forged con-rods achieve required strength at minimum weight for engine efficiency.
Dimensional Consistency
Closed-die forging produces con-rod blanks with consistent dimensions for machining.
Crack-Split Capability
We forge C70 grade blanks suitable for modern fracture-split connecting rod design.
OEM Tooling Development
We develop con-rod forging tooling from customer and engine OEM drawings.
Near-Net Forgings
Near-net con-rod forgings reduce machining cost and material waste.
High-Fatigue Forged Connecting Rods
Shivam Forge is a precision connecting rod forging manufacturer in India producing high-quality forged con-rods and connecting rod blanks for diesel engines, petrol engines, agricultural machinery, compressors and high-performance applications. Our connecting rod forgings deliver the fatigue life and dimensional accuracy modern engines demand.
Connecting rods experience complex combined stresses — tension, compression and bending — at high frequency throughout engine service. The forging process aligns grain flow along the length of the connecting rod, creating a component with significantly superior fatigue resistance compared to cast connecting rods. This is why production engines from all leading OEMs use forged connecting rods.
We manufacture connecting rod forgings in 42CrMo4, C70, EN24 and other alloy steel grades using precision closed-die hot forging. Near-net forging geometries minimize the machining allowance while maintaining the full grain flow integrity of the forging. We also manufacture fracture-split-ready C70 grade connecting rod blanks for modern crack-split production processes.
Shivam Forge supports engine OEMs, connecting rod manufacturers and engine rebuilders with precision forged connecting rod solutions. Our engineering team develops forging tooling from customer drawings and supports the complete product development cycle from prototype through to serial production.
Frequently Asked Questions
What connecting rod forgings does Shivam Forge manufacture?
We manufacture forged connecting rods for diesel engines, petrol engines, agricultural engines, compressors and high-performance applications.
What materials are used for connecting rod forging?
We use 42CrMo4, C70, EN24, SAE 4340, 36CrNiMo4 and other alloy steel grades based on engine type and performance requirements.
Why are forged connecting rods preferred over cast?
Forged connecting rods have superior fatigue strength, better strength-to-weight ratio and more consistent mechanical properties, which is essential for reliable engine operation.
