The Kartboy Endlinks have been designed to be direct replacements of your weak, factory OEM units. The OEM units over time can become weak and flex which can hinder the performance to your vehicle. The Kartboy units are made from high-grade aluminum, and will provide your vehicle with better feedback when cornering. These end links are one of the most embraced and popular upgrades because of the result to modification ratio. These are perfect for those who enjoy a weekend track event, or who likes to participate in the casual canyon cruise.
