Product Description
The 54500-3J000 is a front lower control arm assembly engineered with anti-deformation structural design for multiple Hyundai and Kia platforms produced from 2007 to 2012. This chassis component features reinforced mounting points and premium bushings formulated to resist oil degradation and cracking, with a crimped metal-reinforced dust boot on the ball joint for extended service life. All welds undergo ultrasonic inspection during production. Certified under IATF16949 structural safety standards and produced to match OEM specifications, it suits value-range parts programs and high-volume older vehicle aftermarket operators in commercial procurement.

The control arm body is constructed with HSLA stamped steel or STKM13A welded steel tubing, paired with reinforced gusset plates at all bushing mounting points. This structure reduces flex and deformation under sustained load and impact, maintaining consistent suspension geometry over extended service cycles. All weld joints undergo ultrasonic inspection to detect internal defects, ensuring structural integrity for high-mileage and rough road operation.
The inboard rubber bushings use a compounded natural rubber formula engineered for resistance to oil exposure and cracking. Tuned for directional compliance, the bushings deliver lateral stiffness for stable handling while absorbing vertical impacts from uneven road surfaces. The formulation slows degradation caused by road grime and under-hood oil vapor, extending bushing service life compared to economy-grade synthetic alternatives.
The ball joint assembly features a crimped metal-reinforced dust boot that seals out dust, water and road debris more effectively than standard rubber-only boots. This design preserves internal grease and reduces contamination-related wear on the spherical bearing. The forged alloy steel stud with PTFE-lined bearing maintains smooth articulation across the full suspension travel range.
Installing a new control arm restores factory camber, caster and toe-angle specifications that may drift due to fatigued bushings or impact-related bending. Restoring these parameters addresses uneven tire wear, steering pull and directional instability, while also eliminating suspension clunking noises caused by worn components. Professional 4-wheel alignment is mandatory after replacement to restore full factory geometry.
This control arm is specified for Hyundai i30 (Elantra GT) compact vehicles from model years 2007 to 2012, as well as Veracruz and Rio platforms from the same production period. It mounts to the front lower chassis position, matching original equipment mounting points and connection dimensions. Buyers may cross-reference the OEM part number 54500-3J000 with vehicle VIN information to confirm fit for specific vehicle configurations.
This is an aftermarket replacement part manufactured to meet or exceed original equipment specifications. It matches the fit, form and function of the genuine part, and is available at a competitive price point for volume procurement.
This part is designed for select Hyundai Veracruz, i30 and Kia Rio models produced from 2007 to 2012. For vehicles not listed, contact customer support with a VIN number for fit verification.
Standard automotive hand tools are sufficient for most installations. A torque wrench is recommended to ensure all fasteners are tightened to factory specifications. Refer to a professional service manual for the specific vehicle model for detailed procedures.
Warranty coverage applies to manufacturing defects under normal use conditions. Improper installation, racing use or product modifications void warranty coverage. Refer to the full warranty policy for complete details.
Replacing related wear items at the same time, including both left and right control arms, seals and associated fluids, supports balanced operation and reduces repeated labor costs for service operations.
Cross-referencing the OEM part number 54500-3J000 with a vehicle’s VIN through an authorized dealer or online compatibility checker is the most reliable method to confirm fitment.
This control arm supports a minimum order quantity of 500 units, with scalable options for high-volume aftermarket programs. Available packaging includes genuine Mobis standard packaging, neutral aftermarket packaging and custom brand packaging. Customized order configurations for quantities between 500 and 1000 units are also supported to accommodate different commercial operation scales.
