• For instance, Moog’s arms are designed for steering support and safer operations. The MOOG steering system facilitates smooth, predictable steering and enhances performance even in the most challenging conditions. Its premium one-piece forged steel housing provides increased durability.
• Recent advancements in steelmaking and manufacturing techniques have resulted in the creation of higher-strength and more cost-effective alloy steels, further positioning them as an appealing choice for automotive manufacturers.
• These trends, factors, analysis, and developments in the alloy steel segment would further drive the idler arm market size during the forecast period.

By Vehicle Type:

Based on the vehicle type, the market is segmented into passenger vehicles and commercial vehicles.

Trends in the vehicle type:

• The growth of the global automotive industry directly influences the demand for advanced automotive products and solutions. The rise in vehicle production across all segments leads to an increased need for original equipment and replacement parts.
• Older vehicles tend to experience greater wear and tear, resulting in an increased probability of requiring steering systems replacements. This factor drives a consistent need for replacement parts in the aftermarket.

The passenger vehicle segment accounted for the largest revenue share in the year 2024.

• Passenger vehicles constitute a significant segment of the global market, which includes sedans, hatchbacks, SUVs, and crossovers. These systems are essential for sustaining steering stability, which facilitates smooth handling and control for both drivers and passengers.
• To cater driver comfort and vehicle dynamics, automotive manufacturers are eager to incorporate advanced suspension components, such as steering systems, to enhance handling characteristics and reduce vibrations.
• For instance, in October 2022, Hitachi Astemo, Ltd. has unveiled a prototype for an advanced steer-by-wire steering system. This innovative technology eliminates the need for traditional steering wheels, thereby increasing cabin space. Such advancements are essential for the development of future-generation vehicles and autonomous cars.
• Thus, factors such as focus on driver comfort would further supplement the idler arm market growth during the forecast period.

The commercial vehicles segment is anticipated to register the fastest CAGR during the forecast period.

• The global market in the realm of commercial vehicles is experiencing increased need due to the development of the commercial transportation sector and the rise of heavy-duty vehicles. Commercial vehicles such as trucks, buses, and utility vehicles operate under harsh conditions and face greater loads and stress more than passenger vehicles. The arm plays a vital role in sustaining steering accuracy and stability, which is essential for safe and efficient operation.
• As fleet operators and logistics companies prioritize vehicle safety, reliability, and operational efficiency, there is a growing need for strong and durable suspension components, leading to the adoption of advanced automotive solutions in the commercial vehicle sector.
• Manufacturers of steering systems are under pressure to create products that can withstand tough operating conditions while providing optimal performance and durability.
• Thus, emphasis on durability, reliability, and customizable performance presents prospects for innovation and product differentiation within the commercial vehicle segment, driving the trends of the idler arm market growth.

By Sales Channel:

Based on the sales channel, the market is segmented into OEMs and aftermarket.

Trends in the sales channel:

• Online sales platforms are becoming increasingly prominent, providing convenient access to a diverse selection of automotive products for consumers and repair shops. This trend is anticipated to persist, further disrupting traditional distribution channels.
• Both OEMs and aftermarket suppliers are placing greater emphasis on quality and reliability. This shift is influenced by consumer expectations and the necessity to uphold vehicle safety and performance.

OEMs segment accounted for the largest revenue share in the year 2024.

• OEMs, which include vehicle manufacturers, are pivotal in the initial integration of steering systems into new vehicles throughout the production process. These collaborations with OEMs typically involve long-term contracts to guarantee the integration of steering systems that comply with rigorous quality standards and specifications.
• The OEM segment gains from the consistent requirement for automotive products, fuelled by rising vehicle production volumes and the ongoing necessity for suspension components that promote vehicle safety, stability, and performance.
• Technological innovations in suspension systems and an increasing focus on driving comfort further enhance the demand for high-quality steering systems from OEMs.
• Thus, rise in technological innovations would further supplement the global market during the forecast period.

The aftermarket segment is anticipated to register the fastest CAGR during the forecast period.

• The aftermarket segment is driven by factors including vehicle age, wear and tear, and the necessity for component replacements due to damage or malfunction. As vehicles age and accrue mileage, components like suspension parts, may experience wear and need replacement to ensure optimal vehicle performance and safety.
• In this segment, a varied ecosystem of distributors, retailers, and e-commerce platforms primarily facilitates the distribution and sale of steering systems to end consumers. These channels provide a broad selection of automotive products, accommodating different vehicle makes and models as well as the budgetary needs of vehicle owners.
• Aftermarket suppliers frequently emphasize value-added services such as product warranties, technical support, and installation assistance to distinguish themselves in a competitive market environment.
• For instance, in March 2021, SKF India’s automotive aftermarket segment launched three new products designed to meet the evolving needs of customers across various sectors in India. The new offerings include Steering and Suspension Systems for 4-wheelers, Timing Belts, and Chain and Sprockets for 2-wheelers. This innovative product range features high quality, superior strength, and long-lasting durability.
• As the automotive industry continues to evolve, aftermarket sales channel expected to remain essential contributor to the continued development and innovation within the global market share.
