Control Arms

Control Arms: Configurations, Interfaces and Fitment

Control arms connect the wheel carrier or steering knuckle to the vehicle subframe or body. Their shape, mounting points and integrated components vary widely between vehicle platforms, which makes accurate specification essential to every control arm order.

Product Types

Control Arms Overview

01

Lower control arms

Typically carry significant load and locate the bottom of the knuckle; often A-shaped or L-shaped.

02

Upper control arms

Used in double-wishbone and multi-link layouts to locate the top of the knuckle.

03

Lateral and trailing arms

Single links used in multi-link rear suspensions to control specific directions of movement.

04

Arm assemblies

Arms supplied with pressed-in bushings and an integrated or bolted ball joint.

Function

What These Components Do

  • Connect the knuckle to the chassis through pivoting mounts
  • Hold camber and caster geometry within the intended range
  • Carry longitudinal and lateral forces from the wheel
  • Provide mounting points for bushings and ball joints

Before Ordering

Specifications Buyers Should Confirm

  • Arm configuration and position (upper / lower, front / rear, left / right)
  • Mounting point spacing and bolt hole diameters
  • Bushing interface: integrated bushing type and orientation
  • Ball joint interface: integrated, riveted or bolted; stud taper and thread
  • Arm construction as specified by your reference sample or drawing

Fitment

Application & Fitment Considerations

We do not claim vehicle compatibility without verification. Every application is confirmed against the references you provide.

  1. 01

    Arms for the same model can differ by drivetrain, engine or suspension package.

  2. 02

    Bushing orientation and ball joint stud geometry must match the original design.

  3. 03

    Confirm whether the buyer requires the bare arm or a complete assembly.
