    Why It Exists

    Built By Someone Who Needed It

    Trick Billet started in the workshop, not a boardroom — a billet aluminum radiator filler neck designed to solve a real problem on a real street/race car. Removing the ugly overflow tube from the radiator filler neck.

    Race Proven

    Built On A Real Street/Race Car, Not A Test Bench

    Under the hood — Neatness is everything

    Under the hood — Neatness is everything

    Trick Billet Filler Neck was tested and refined for years before releasing to the public. Proven and tested on a real, race-driven car — not a bench fixture. Repeated heat cycles, vibration, and hard runs are what the product actually has to survive before it ever reaches a customer. Simple to install with minimal aluminium welding.
