You’ve already installed a stiffer sway bar — now it’s time to make it work properly. The stock Subaru endlinks are flexible, weak, and prone to failure when paired with performance suspension components. The Kartboy Front & Rear Endlink Combo replaces those flimsy OEM parts with solid, performance-focused components built to handle serious cornering loads.
Constructed from CNC-cut, hard-anodized 6061-T6 aluminum, these endlinks feature urethane bushings that provide the perfect balance of stiffness and controlled movement for predictable, confident handling. Designed for both street and track use, they ensure your sway bars deliver maximum efficiency and response.
Features:
Precision CNC-machined from 6061-T6 aluminum for strength and light weight
Durable hard-anodized finish to resist corrosion and wear
Urethane bushings for controlled flex and improved steering feedback
12mm hardware for a secure, direct fit
Designed for OEM and aftermarket sway bars (spacers recommended for aftermarket setups)
Made in the USA
Combo Includes:
Front Endlinks (p/n KB-017F-12MM)
Rear Endlinks (p/n KB-017-08+REAR)
