The Tekno RC TKR9055 Hinge Pin Bushings (8‑Pack) are essential suspension components designed to provide smooth rotation and reduce unwanted movement between the hinge pins and suspension arms. These bushings help maintain proper suspension geometry by minimizing slop, resulting in more consistent handling and improved overall performance on a variety of surfaces. They are compatible with many Tekno RC platforms that use standard hinge pin setups, making them a reliable replacement or upgrade when rebuilding or maintaining your truck or buggy’s suspension system.
