Connecting Rod Assembly Manufacturer in Rajkot | RADO Engineering
RADO Engineering is a trusted name in connecting rod manufacturing, based in Rajkot, Gujarat, delivering precision engineered components for internal combustion engines used across the automotive industry. We specialize in producing high strength 2 wheelers connecting rod and 3 wheelers connecting rod assemblies, crafted from premium OEM 8620 alloy steel to withstand the high stress, high cycle demands of modern motorcycle, scooter, and auto rickshaw engines delivering OEM level performance, dimensional accuracy, and long operational life at competitive prices.
What Is a Connecting Rod Assembly?
A connecting rod (con rod) is one of the most critical components in any two wheeler or three wheeler engine. It forms the mechanical link between the piston and the crankshaft, converting the linear (up down) motion of the piston into the rotational motion that drives the wheels.
Whether it's a lightweight 2 wheelers connecting rod built for high RPM motorcycle and scooter engines, or a heavier duty 3 wheelers connecting rod engineered for the load carrying demands of auto rickshaws and commercial three wheelers, the component endures tremendous compressive and tensile forces with every combustion cycle. This makes material quality, precision machining, and bore accuracy non-negotiable at RADO Engineering.

Product Overview
As a specialist in connecting rod manufacturing, RADO Engineering produces assemblies using OEM 8620 case hardening steel, a nickel chromium molybdenum alloy chosen for its exceptional toughness, surface hardness after heat treatment, and fatigue resistance under cyclic loading conditions.
Our range covers both 2 wheelers connecting rod assemblies for motorcycles and scooters, and 3 wheelers connecting rod assemblies for auto rickshaws and light commercial three wheelers, all manufactured to exact OEM specifications and compatible with a wide range of popular vehicle models from leading brands such as Hero, Honda, TVS, Yamaha, Kinetic, Mahindra, LML, Suzuki, and Bajaj.
Key Features
Superior Material — OEM 8620 Alloy Steel
A low carbon nickel chromium molybdenum steel widely used in high stress automotive components, offering an ideal balance of core toughness and case hardness — the material of choice for both 2 wheelers connecting rod and 3 wheelers connecting rod applications operating under continuous fatigue loading.
High Tensile Strength
Every connecting rod assembly, two wheeler or three wheeler, is engineered to withstand peak combustion pressures without deformation or failure, extending engine life and maintaining consistent power output.
Precision Boring of Big End & Small End
Both the big end (crankshaft side) and small end (piston pin side) bores are precision machined to tight dimensional tolerances, ensuring proper bearing fit, eliminating side play, and reducing vibration and premature wear.
Excellent Dimensional Accuracy
Every unit undergoes strict dimensional verification — length, straightness, twist, and weight matching — for smooth engine operation across the full RPM range, whether fitted in a two wheeler or a three wheeler engine.
Corrosion Resistance
Quality grade steel and surface treatments protect against oxidation and corrosion in the oil rich, high temperature environment of a running engine.
Durable & Long Operational Life
Built for durability, RADO connecting rods reduce replacement frequency and lower total cost of ownership for end users, distributors, and fleet operators alike.

RADO's connecting rod manufacturing capability serves a wide range of applications:
Motorcycles
100cc to 200cc single cylinder engines (Hero, Bajaj, TVS, Honda compatible 2 wheelers connecting rod assemblies)
Scooters
Automatic transmission two wheelers with internal combustion engines
Auto Rickshaws & Three Wheelers
