These extended wheel hex adapters are a game-changer for your ARRMA 3S models! They convert your 14mm hexes to 17mm, allowing you to run larger, more aggressive tires. The 10mm extension on each side widens your wheelbase by 20mm total, giving you significantly better stability and reducing rollovers on rough terrain. Compatible with ARRMA Vorteks, Senton, Granite, Infraction, Big Rock, and Vendetta 3S BLX models, plus the Mega series. The splined design ensures precise alignment with splined wheels, and the closed-end nuts with O-rings keep dirt out for a secure fit. Made from precision-machined aluminum, they're strong and lightweight. Installation is straightforward - just replace your stock hexes with these upgraded ones. The red color adds a nice custom touch to your RC. Being able to use 17mm wheels opens up tons of tire options that weren't available with the stock 14mm setup. The wider stance makes a noticeable difference in handling, especially when cornering at speed or driving over uneven surfaces. Definitely one of those upgrades that actually improves performance rather than just looking cool!
