RC enthusiasts, listen up! If you're tired of snapping those plastic suspension arms on your Traxxas Revo or E-Revo (1/10 scale models made before 2017), this upgrade is for you. These are INTEGY's billet machined Type II upper rear suspension arms. Instead of plastic, they're made from solid aluminum that's been precision machined and anodized in this cool blue color (other colors available too). They are WAY stronger and more durable. They feature Delrin inserts where the suspension shaft goes, which reduces wear and gives a smoother action. They even have removable stiffening plates, so you can tune the flex of the arm for different driving styles or tracks. They come as a pair (left and right). INTEGY is a top brand in the RC aftermarket, known for quality materials and craftsmanship. Installing them is a straightforward DIY job that'll seriously improve the toughness and performance of your truck. If you bash hard or race and want to stop breaking parts, these metal arms are a must-have upgrade. Your Revo will thank you.
