These are performance upgrade commutator brushes for Aurora T-Jet and Thunderjet HO scale slot cars. The pack includes 24 brushes made from a 80% copper and 20% silver blend, which is great for better conductivity and smoother running—basically a 'hop-up' part to make your car faster and more reliable. They're brand new, original (not reproductions), from Dash Motorsports, and fit the T-Jet chassis. Perfect if you're into slot car racing or restoring old Aurora sets and want to replace worn brushes or boost performance. They don't have a UPC, but they're genuine parts from 2014-ish. Just pop them in place of the old ones and enjoy less electrical resistance and better contact. A simple upgrade that can make a noticeable difference on the track.
