Material Characteristics:
The control arm body is stamped from SPHC steel, a hot-rolled steel grade with stamping formability and weldability suited to suspension components subject to cyclic loading. The ball joint pin is made from 40Cr alloy steel, heat-treated to provide surface hardness alongside core toughness for absorbing steering and suspension loads. The bushing is molded from natural rubber, providing elastic recovery and resistance to weathering, and functions to dampen road vibration at the arm-to-subframe connection point.
Surface Treatment and Color:
The part surface is finished with E-coating, applied evenly across the interior, exterior, and weld areas of the arm body to slow steel oxidation under humid or salt-exposed conditions. The coating layer is applied at a consistent thickness with a matte finish comparable to the original equipment part, allowing direct installation without additional painting or coating steps.
Structural Characteristics:
The arm body is a stamped and welded single-piece structure, with mounting hole positions matching OE subframe and steering knuckle interfaces
The ball joint pin is press-fitted at the end of the arm and sealed with a dust boot to limit dirt and moisture ingress
The rubber bushing is press-fitted into the arm sleeve through an interference fit, isolating suspension vibration from the vehicle body

Basic specifications of the Hyundai Sonata NF upper control arm
Installation and Adaptability:
This upper control arm is developed to the dimensions of OE numbers 54410-3K00 (right side) and 54420-3K000 (left side), with mounting hole positions, ball joint pin diameter, and bushing outer diameter matching the original suspension system of the Hyundai Sonata NF (2005-2010). No modification to the subframe or steering knuckle is required during installation. When replacing the part, it is advisable to inspect the steering knuckle ball joint seat and subframe bushing mounts for wear, and to tighten the ball joint nut and bushing mounting bolts to the specified torque to restore suspension alignment parameters to OE settings.
Application:
This part is used for suspension repair and replacement on the Hyundai Sonata NF, serving auto repair shops, dealership parts departments, aftermarket retail chains, and overseas auto parts distributors for routine stock replenishment. It can also serve as an additional SKU within a suspension product line, sold alongside other chassis parts such as lower control arms, sway bar links, and ball joints.
Product Advantages and Features:
Developed to OE numbers and dimensions, with both left- and right-side part numbers available for direct fitment
Ball joint pin made from heat-treated 40Cr alloy steel, built to withstand cyclic suspension loads
Full E-coating coverage slows steel oxidation under humid operating conditions
Stock delivery within 1-7 days supports aftermarket replenishment timelines
