This aluminum shock absorber set is designed as a suspension upgrade for 1/18 scale RC vehicles. CNC-machined aluminum shock bodies provide improved strength and durability compared to stock plastic parts, helping enhance suspension stability and impact absorption. The threaded shock design allows easy preload adjustment to fine-tune ride height and suspension response for different terrain and driving styles. These are oil-type shocks and are not pre-filled with oil, allowing users to choose their preferred shock oil for customized damping performance. Ideal for RC hobbyists looking to improve suspension control, durability, and overall driving performance.
