L6 Return Spring Bracket - Mount Under Stock Heatshield

A purpose-built throttle return spring bracket for the Nissan / Datsun L6 engine, designed to mount cleanly under the stock heat shield. CAD designed and fabricated by ZSM Custom, this bracket provides a secure, properly positioned anchor point for the throttle return spring — keeping everything tucked away and out of sight beneath the factory heat shield for a clean, OEM+ result.

On ITB and performance carburetor builds, a reliable throttle return is non-negotiable. This bracket solves the mounting problem properly, without improvised solutions or exposed hardware cluttering the engine bay.
