Project Kics Leggdura Racing Tire Valve Stem Caps
When enthusiasts invest in a premium wheel setup, every detail matters — right down to the valve stem caps. Project Kics approaches these small-but-visible components with the same engineering philosophy that defines the rest of their wheel accessory lineup, delivering caps that are purpose-built to complement a high-quality build rather than detract from it.
The Leggdura Racing Line
Project Kics' signature valve stem cap offering is the Leggdura Racing series. The name itself says a lot: Leggdura is derived from the Italian "leggero" (light) and "duralumin" — a nod to the lightweight, high-strength aluminum alloy at the heart of these caps. The Leggdura Racing valve caps are made in Japan from forged A7075-T6 aluminum alloy , the same grade of material found in aerospace and motorsport applications. This is a significant step above the stamped or cast aluminum commonly used by generic aftermarket valve caps.
These valve stem caps are made by legendary Project Kics to match your lug nut finish — a design choice that resonates strongly with the tuner community, where cohesion across every wheel component is a point of pride. Since the caps are larger than OEM ones, they add a refined, purposeful touch to your wheels without looking out of place on either a street build or a dedicated track car.
Color Options and Fitment
The Leggdura Racing valve caps are available in a range of anodized finishes — including Black, Gold, Bronze, and Green — allowing builders to coordinate or contrast with their lug nut color of choice. Each set includes 4 pieces and measures 17mm in length , making them a straightforward, universal fitment upgrade for virtually any passenger vehicle.
Why Project Kics in This Category?
The Kics Project is a member of the larger KYO-EI industrial corporation, specializing in the manufacture of high quality metal based products. For over 50 years, KYO-EI has led design and manufacturing of high-quality automotive accessories, and Project Kics continues that legacy with precision-engineered products produced in Japan to ISO, NAPAC, and JAB standards. That heritage of quality control trickles all the way down to the valve stem cap — a part most brands treat as an afterthought.
Project Kics is a go-to choice among tuners, time attack teams, and street car builders for one simple reason: they take the smallest parts of your build seriously. The Leggdura Racing valve caps are a direct expression of that ethos — a functional, forged-aluminum accessory that protects your valve cores from dust and debris while tying together the aesthetic of your entire wheel package.
