FRONT UPPER ARM CONSTRUCTION

BHE021334200T01

• The front upper arm is made of liquid-forged aluminum for improved rigidity and weight reduction.

• Newly developed zero-stopper-clearance rubber bushings have been adopted for where the upper arm attaches to the front crossmember.

  – The stopper sleeve, integrated with the inner pipe, protrudes slightly.
  – This structure suppresses forward-backward movement caused by external forces acting on the arm.
  – It also enables linear spring characteristics of the bushings from an early stage, thereby optimizing control over changes in vehicle behavior.
