Description

The Kartboy KB-9009 is a complete front and rear swaybar endlink combo engineered to optimize the performance of your Subaru WRX or STI's suspension. By upgrading from stock endlinks, you can expect a more responsive and stable driving experience, especially during spirited driving or cornering. Kartboy, a brand renowned for its precision-engineered Subaru performance parts, manufactures this endlink kit in the USA. The company emphasizes quality and durability, offering a lifetime warranty on its products, reflecting confidence in their craftsmanship and materials. This commitment ensures that the KB-9009 combo is a reliable upgrade for enthusiasts seeking to enhance their vehicle's chassis dynamics. This swaybar endlink combo is specifically designed for the 2015-2021 model years of the Subaru WRX and Subaru STI. When you've already invested in a stiffer sway bar to flatten your cornering, these Kartboy endlinks are the necessary upgrade to make that sway bar function as intended, delivering the tight suspension response you desire.
