The factory front subframe (Part Number: 54401-JK02A) on the Nissan 370Z and Infiniti G37 includes a forward-mounted, C-shaped aluminium support section that is highly susceptible to damage. Whether from minor collisions, road debris, or improper jacking, this piece is commonly bent or collapsed, compromising both structural integrity and undertray mounting.

The problem? Nissan does not offer this component separately. A damaged section typically means replacing the entire front subframe, turning a simple repair into a costly, labor-intensive job.

Z1’s Front Subframe Repair Section provides a direct-fit solution that eliminates the need for full subframe replacement. Designed to match OEM geometry and appearance, this aluminium section bolts directly into place using factory mounting points, restoring proper support, alignment, and undertray functionality at a fraction of the cost. Ideal for collision repair or correcting damage from improper lifting, this repair section delivers OEM-like fitment without the expense or complexity of replacing the entire subframe.
