This product is an upper 4-link bar designed as a replacement suspension component for compatible Losi RC vehicles. It helps maintain proper axle positioning and suspension geometry by connecting the chassis to the axle assembly in a 4-link suspension setup. The rigid yet durable construction ensures consistent alignment under load while allowing controlled suspension movement over rough terrain. Precision-molded ends provide accurate fitment with factory mounting points for straightforward installation. Ideal for replacing worn or damaged links and restoring proper suspension performance and stability.
