Product Description

The **King Shocks BS2040** hydraulic bump stop is a performance suspension component designed to offer progressive bottom-out control for vehicles with high travel shocks - especially in off-road, rock crawling, and aggressive terrain applications. Rather than relying on simple rubber bumpers, this hydraulic bump stop uses precision machined components and advanced piston design to provide controlled damping throughout the suspension's travel.

With a **2.0" body diameter** and **4" travel**, the BS2040 delivers smooth, tunable resistance as the suspension approaches full compression, helping protect chassis and suspension components from hard impacts. Built with high-quality aluminum and Chromoly materials, and featuring double sealed Schrader covers and micro-polished shafts, it's engineered for durability and serviceability. Because it's fully rebuildable and re-valvable, you can fine-tune its performance to match your vehicle's weight and driving style.
