Product Description
The 54500-A7100 is a complete front left control arm assembly engineered for Kia Forte YD and Cerato YD second-generation vehicles produced from 2014 to 2018. This chassis component comes with pre-installed natural rubber bushings and a press-fit ball joint, eliminating separate pressing operations during on-site installation. Manufactured to match Mobis / Hyundai-Kia suspension specifications and certified under IATF16949 structural safety standards, it serves as a replacement option for compact car parts specialists, aftermarket distributors and retail chains in commercial procurement.

The arm body is stamped from HSLA sheet steel, which delivers higher yield strength than mild steel while retaining formability for curved geometries. In collision events, the material exhibits progressive plastic deformation to absorb impact energy in a controlled manner, supporting passenger compartment integrity while enabling designed deformation at crumple zone interfaces. The e-coat surface finish provides resistance to road salt corrosion for extended service life in winter salting regions.
Inboard mounting bushings use compounded natural rubber with tuned durometer and internal geometry to deliver directional-specific compliance. The structure provides lateral stiffness for steering precision, while allowing vertical compliance to absorb impacts from potholes and road expansion joints. The rubber formulation resists cracking, tearing and oil-induced degradation over service cycles.
The factory-pressed ball joint is installed to controlled tolerance levels to support precise fit between the control arm and steering knuckle. This pre-assembly removes on-site pressing requirements for repair shops, reducing labor time and avoiding fit errors that may cause premature wear. The forged alloy steel stud with PTFE-lined bearing maintains smooth articulation across the full suspension range of motion.
A new control arm restores factory-specified camber, caster and toe-angle parameters, which may drift out of specification due to bent or fatigued original arms. Restoring these parameters addresses uneven tire wear, directional instability and altered scrub radius that affects braking performance. Fresh bushings also reduce suspension clunking over bumps and lower road noise transmitted into the cabin. Professional wheel alignment is required after replacement.
This control arm fits Kia Forte / Cerato compact sedan vehicles from model years 2014 to 2018, mounting to the front left lower position of the chassis system. It matches original equipment mounting points and connection dimensions. Buyers may cross-reference the OEM part number 54500-A7100 with vehicle VIN information through authorized dealers to confirm fit for specific trim 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.
This part is designed for Kia Forte YD and Cerato YD models from 2014 to 2018. 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-A7100 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 flexible packaging options for compact car parts specialists and retail chains. 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 for commercial procurement needs.
