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

The Internal Bypass technology allows for adjustable damping zones within the shock body. This means you can achieve better control over different types of impacts, from small trail chatter to large hits, without compromising ride comfort.

Why does the piggyback reservoir help?

The piggyback reservoir holds additional oil and nitrogen, which helps to keep the shock cooler during extended use. This is crucial for preventing shock fade, ensuring consistent damping performance even under demanding conditions like high-speed driving or long off-road excursions.

Can I install these shocks on a stock vehicle?

These shocks are designed for custom suspension builds and offer 16 inches of travel. Installing them typically requires significant modifications to your vehicle's suspension geometry, such as custom control arms and extended brake lines, to properly utilize the travel.

Product Details

This is the King Shocks 2.5" PR Smoothie Shock with a Piggyback Reservoir and Internal Bypass (IBP) technology. It's built for serious off-road use where you need precise damping control over a wide range of terrain. The 16-inch stroke length offers substantial travel, making it ideal for custom suspension builds or significant upgrades on vehicles designed for extreme articulation and high-speed desert running.

What sets this shock apart is the combination of King's renowned Smoothie shock body with their advanced Internal Bypass system and a piggyback reservoir. The IBP technology allows for adjustable damping zones within the shock body itself, giving you improved control over both small bumps and large impacts without sacrificing comfort. The piggyback reservoir holds extra oil and nitrogen, which helps dissipate heat more effectively during prolonged use, preventing shock fade. This means consistent performance whether you're crawling over rocks or hitting whoops at speed. The 2.5-inch diameter shock body is a popular size for custom applications, offering a good balance of damping capacity and physical space requirements.

When installing these shocks, you'll want to ensure your vehicle's suspension geometry can properly utilize the 16 inches of travel. This often involves custom control arms, extended brake lines, and potentially other suspension modifications. King Shocks are known for their rebuildable design, meaning you can service and tune them for years to come. This shock is sold individually, so plan accordingly for your vehicle's axle configuration.
