This product is a set of four aluminum sway bar collars designed for Tekno RC 1/8 scale platforms such as the EB48, NB48, ET48, MT410, and SCT410 series. It replaces the stock plastic collars and helps secure the sway bar assembly more firmly in the chassis, preventing unwanted movement during high-load racing or bashing conditions. The collars are CNC-machined from aluminum and hard-anodized for improved durability, reducing the chance of damage from over-tightening or impact compared to plastic parts. They are direct-fit replacements that help maintain consistent sway bar performance and suspension balance under demanding off-road use.
