What is the benefit of the Internal Bypass (IBP) design?

The IBP design allows the shock absorber to provide different damping rates based on its position in the suspension travel. This means it can offer a more comfortable ride over small bumps while still providing significant resistance to bottoming out on large impacts.

Why is a remote reservoir important for this shock?

The remote reservoir holds extra shock oil, which helps to keep the shock cooler during extended use. This improved heat dissipation is critical for maintaining consistent damping performance and preventing shock fade, especially in demanding off-road conditions.

Can this shock absorber be rebuilt?

Yes, this King Shocks Race Smoothie shock is designed to be rebuilt. This allows for long-term serviceability and ensures that the shock can be maintained and tuned for optimal performance over many years of use.

Product Details

King Shocks is well-known for building high-performance suspension components for off-road racing and extreme use. This 18-inch, 3.5-inch diameter IBP Race Smoothie shock absorber is a prime example of their commitment to durability and performance when it matters most. It's designed to handle the rigors of competitive off-road environments, offering precise control and damping capabilities.

This shock features an Internal Bypass (IBP) design, which allows for position-sensitive damping. This means the shock can provide a softer ride in the initial travel for comfort and small bumps, while stiffening up in the latter stages of compression to prevent bottoming out on large impacts. The 3.5-inch smooth body shock is paired with a remote reservoir that contains additional oil and allows for better heat dissipation, crucial for maintaining consistent damping performance during long, hard runs. The 1-inch diameter shaft is robust and built to withstand significant side loads encountered in off-road conditions. The included hose allows for flexible mounting of the remote reservoir, giving you options for installation and helping to keep the shock cool.

This shock absorber is a serious piece of equipment for anyone building a dedicated off-road race vehicle or a high-performance custom suspension. It's built to be rebuilt, allowing for long-term serviceability. When installing, ensure you have the appropriate mounting hardware and consider consulting with a suspension specialist to dial in the valving for your specific application and vehicle weight.
