What makes this shock absorber 'external bypass'?

External bypass shocks have additional tubes that allow oil to bypass the main piston. This lets you fine-tune the damping characteristics, offering more control in specific parts of the suspension travel, especially useful for aggressive off-road driving.

Is this shock absorber easy to maintain?

Yes, this shock is designed to be owner serviceable and rebuildable. This means you can perform maintenance and rebuilds yourself, allowing you to keep it performing optimally over time.

What is the benefit of the Cerakote coating?

The proprietary Cerakote protective ceramic coating over the zinc-plated basecoat offers enhanced resistance to abrasion and corrosion. This helps protect the shock body from the harsh elements and debris encountered during off-road use.
