Replacement left-hand front upper suspension arm / wishbone for Mazda MX-5 Mk3 / Mk3.5 / Mk3.75 (NC) 1.8L and 2.0L models listed in the compatibility table.

The front upper suspension arm is part of the MX-5 NC front double-wishbone suspension layout. It helps locate the top of the front hub / steering knuckle assembly, controlling suspension geometry, camber movement and wheel position as the suspension moves.

There is typically one left-hand front upper suspension arm fitted per vehicle. This listing is for the left-hand / LH front upper arm only.

This part is commonly replaced when the original arm is bent, corroded, damaged, has worn bushes, has play in the ball joint, or is unsuitable for reuse during suspension refurbishment, accident repair or MOT repair work.
