King Shocks 18in 4.0 Race Shock 7 Tube Bypass Piggyback Res 1.25in Shaft Large 1in Bypass Tubes

This is the King Shocks 4.0 Race Shock with a 7-tube bypass and piggyback reservoir, part number RS4018-BP7P. It's built for serious off-road performance, offering advanced damping control and adjustability that you can feel on the trail. The large 1.25-inch diameter shaft is incredibly strong, designed to handle the rigors of competitive racing and extreme terrain. If you're building a high-performance off-road vehicle where precise suspension tuning is critical, this shock absorber is a top-tier component.

What sets this shock apart is its 7-tube bypass design. Each bypass tube allows oil to flow around the main piston at different points in the suspension stroke, giving you independent control over compression damping in various stages. This means you can fine-tune how the suspension reacts to small bumps, large impacts, and bottom-out events, all without affecting the shock's rebound characteristics. The piggyback reservoir is mounted directly to the shock body, providing additional oil capacity and cooling. This helps prevent shock fade during prolonged, hard use, ensuring consistent performance when you need it most. The large 1-inch bypass tubes are a notable feature, allowing for a wider range of adjustment and more fluid flow for enhanced damping control.

When installing these shocks, you'll want to ensure your vehicle's suspension geometry is set up to take full advantage of their capabilities. Proper alignment and spring rates are crucial for optimal performance. Because these are highly adjustable race shocks, they are often paired with custom suspension setups. It's recommended to consult with a suspension specialist or refer to King Shocks' technical documentation for detailed installation and tuning guidance to achieve the best possible results for your specific application.
