Global automotive steering knuckle market is projected to witness a CAGR of 5.59% during the forecast period, 2025-2032, growing from USD 3.78 billion in 2024 to USD 5.84 billion in 2032. The market for automotive steering knuckles is growing steadily with increased vehicle production, strict safety standards, and increased demand for lightweight but strong suspension components. As vehicle manufacturers focus on better handling and vehicle stability, steering knuckles that play a vital role in wheel alignment and suspension durability are gaining significance in the passenger and commercial vehicle market. The shift towards electric cars continues to drive demand, and manufacturers are designing custom knuckles to suit unique weight distributions and torque levels.

Material technology breakthroughs are remaking the marketplace, with light yet strong advanced aluminum alloys and composites permitting weight savings with structural integrity. Precision engineering is also on the list to refine knuckle designs to provide additional load-carrying capability and corrosion resistance. The aftermarkets sector is increasing as owners demand high-quality replacement parts to maintain suspension performance.

For instance, in July 2024, Hirschvogel Group to be separated from its plant in Columbus/Ohio, USA. The Hirschvogel Group, headquartered in Germany, is a global supplier of steering knuckles with nine plants on three continents. The company is now separating from Hirschvogel Incorporated in Columbus/Ohio (USA), which was founded in 1988 and has been struggling with losses for a long time. In the future, the global player will serve the North American automotive market via its other production sites, primarily via Mexico and India.

New Launches Drive the Market Demand

The automotive steering knuckle industry is experiencing dynamic innovation by launching next-generation solutions designed specifically for changing vehicle architectures. The latest launches include sophisticated high-strength aluminum knuckles that substantially minimize unsprung weight while structural rigidity is retained, which is particularly suitable for electric vehicle performance. Leading suppliers are introducing modular knuckle designs incorporating mounting points for ADAS sensors, enabling autonomous driving functionality. The aftermarket market is gaining from new durable coated versions that provide an extended service life in demanding operating conditions. These product advancements solve key industry requirements - from carrying heavier EV battery loads to allowing accurate wheel alignment in performance vehicles. With vehicle manufacturers further optimizing suspension geometries for better handling and fuel economy, these innovative solutions are increasingly essential across every vehicle class.

For instance, in November 2024, Steel Strips Wheels Limited (SSWL) launched its new product ‘Aluminum Steering Knuckle’ under the automotive component category. The latest product caters to the domestic market. The company also commenced commercial production at the existing manufacturing facility at Mehsana, Gujarat.

Technological Developments Bolster the Demand

The steering knuckle industry is undergoing revolutionary development with advancements in cutting-edge material science and manufacturing technologies. New high-vacuum die-casting processes make it to production intricate, lightweight aluminum knuckle designs with enhanced strength-to-weight ratios. New smart knuckle integrations feature integrated strain gauges and temperature sensors for real-time load monitoring, which is especially important for autonomous vehicle safety systems. Additive manufacturing makes topology-optimized structures possible, minimizing material waste while enhancing stress distribution. These innovations directly address essential industry requirements - from enabling greater EV battery weights to allowing for accurate torque vectoring in performance use cases. Combining self-lubricating bushings and nano-coatings for corrosion resistance to product durability, building new value propositions in OEM and aftermarket markets.

For instance, in September 2023, SuperPro launched a new steering knuckle to prolong tyre life. SuperPro release world-first solution for tyre wear on late-model D-MAX, MU-X and BT-50 models. Isuzu D-MAX, MU-X, and Mazda BT-50s suffer from bump steering issues, resulting in excessive tyre wear and, in some cases, undesirable handling characteristics. The problem presents itself with standard-height vehicles and becomes more prominent as you lift them or add additional weight, like accessories.

Passenger Vehicles Lead the Market

The passenger car segment is the largest market for steering knuckles, fueled by high-volume production and rising performance expectations for all vehicle segments. Sedans, SUVs, and crossovers generate strong demand for accurate knuckle solutions that balance handling accuracy and ride comfort. This segment's dominance is due to the emphasis by automakers on sophisticated suspension geometries and weight reduction measures. The premium vehicle segment calls for sophisticated knuckle designs that accommodate larger wheel sizes and increased torque outputs. Electric vehicle uptake further supports this position, as EVs need specialized knuckles to handle distinct weight distributions and regenerative braking forces. As with ongoing suspension system evolution and model increases, passenger vehicles continue to hold sway over steering knuckle use, fueled by both OEM applications and aftermarket replacement requirements.

For instance, in 2025, across the first two months, new battery-electric car sales grew by 28.4%, to 255,489 units, capturing 15.2% of total EU market share. Three of the four largest markets in the EU, accounting for 64% of all battery-electric car registrations, recorded robust double-digit gains: Germany (+41%), Belgium (+38%), and the Netherlands (+25%). This contrasted with France, which saw a slight decline of 1.3%.

Asia-Pacific Dominates the Market

Asia-Pacific leads the global steering knuckle market due to its status as the world's largest automobile manufacturing base. Demand is led by China, Japan, and South Korea, which have technologically developed automotive manufacturing hubs and are increasingly adopting electric vehicles. This regional dominance is driven by three major drivers: huge passenger vehicle production volumes that need high-quality suspension parts, high safety standards requiring precision knuckle designs, and cost-competitive manufacturing capacity catering to domestic and export markets. The fast EV transition in the region also speeds up demand for customized knuckles designed for electric platforms. With the auto OEMs continuously improving suspension systems and local manufacturers developing lightweight materials, Asia Pacific remains both the production hub and technology center for advanced steering knuckle solutions.

For instance, in May 2023, BYD Company launched the new Han PHEV with DM-i and DM-p hybrid drivetrains. The Han DM-i Champion Edition is equipped with an NFC key function compatible with iOS and Android-based phones. It also has a W-HUD display that shows speed, vehicle information, navigation info, etc. The Han DM-i has an FSD suspension system that adjusts the damping force. Moreover, the suspension arms and steering knuckles of the Han DM-i Champion Edition are made of aluminum.

Future Market Scenario (2025 – 2032F)

Steering knuckles will evolve to accommodate heavier battery loads and unique torque demands in electric vehicles. Lightweight, high-strength materials like advanced aluminum alloys will dominate EV knuckle production.

Embedded sensors will enable real-time load and alignment monitoring for predictive maintenance. Connected knuckles will become integral to autonomous vehicle safety systems.

3D printing will allow complex, topology-optimized knuckle designs with reduced material waste. Localized additive production will streamline supply chains for custom applications.
