King Shocks 12in 4.0 Race Shock 3 Tube Bypass Piggyback Res 1.25in Shaft Large 1in Bypass Tubes

When you're pushing your vehicle hard off-road, especially in demanding race conditions or over challenging terrain, having suspension that can keep up is critical. This King Shocks 4.0 Race Shock is built to handle that kind of abuse, offering advanced adjustability and robust construction to manage extreme suspension travel and impacts. It's designed to provide precise control and damping characteristics, allowing your vehicle to maintain stability and traction when you need it most.

This shock features a substantial 4-inch diameter body, which helps dissipate heat effectively, crucial for maintaining consistent performance during long, hard runs. Inside, a large 1.25-inch diameter shaft handles the heavy loads, while the three external 1-inch diameter bypass tubes offer significant external adjustment capabilities. These bypass tubes allow you to fine-tune the shock's damping curve, controlling how the suspension reacts to different speeds and terrains without needing to open up the shock itself. The piggyback reservoir further aids in cooling and provides additional oil capacity, which is essential for preventing shock fade under intense use. This setup is ideal for custom suspension builds where precise tuning for specific applications is paramount.

Installing a shock like this often involves custom fabrication and integration into a vehicle's existing suspension geometry. It's a component for serious builders and racers who understand the intricacies of suspension tuning and are looking for top-tier performance. Ensure you have the necessary fabrication skills or consult with a professional suspension specialist to properly mount and set up these shocks for your specific vehicle and intended use.
