King Shocks 20in 4.0 Race Shock 5 Tube Bypass Piggyback Res 1.25in Shaft Large 1in Bypass Tubes

The 1.25-inch diameter shaft on this King Shocks 4.0 Race Shock is a strong foundation for handling the intense demands of off-road racing. This shock absorber is built with five external bypass tubes, each featuring a 1-inch diameter, allowing for precise tuning of compression and rebound damping independent of the main piston. This advanced adjustability is crucial for dialing in suspension performance across a wide range of terrain, from high-speed desert runs to technical rock crawling.

The piggyback reservoir design not only adds cooling capacity to help maintain consistent damping performance under heavy use, but it also houses the bypass circuits. This integrated design keeps the overall shock package relatively compact while offering extensive tuning capabilities. The large 4.0-inch diameter main body provides ample fluid capacity for heat dissipation and consistent damping. King Shocks are well-known in the racing community for their robust construction and the ability to be rebuilt and re-valved, ensuring a long service life and the ability to adapt to changing needs or vehicle setups.

This shock is designed for serious off-road applications where precise control and durability are paramount. While specific vehicle fitment isn't listed here, these shocks are typically adapted to custom off-road builds. It's important to consult with a suspension specialist or King Shocks directly to confirm compatibility and determine the correct mounting hardware and valving for your specific application. Proper installation and setup are key to unlocking the full performance potential of these high-end race shocks.
