What makes this shock absorber different from a standard one?

This FOX shock uses a race-proven damping system with an internal floating piston and hydraulic top-out piston for improved on-road comfort and off-road handling. It's also built with a durable aluminum body and is designed to be rebuilt and re-tuned.

What does 'IFP' and 'HTO' mean for this shock?

IFP stands for Internal Floating Piston, which helps separate the oil and nitrogen gas to prevent cavitation and maintain consistent damping. HTO means Hydraulic Top Out, which provides a controlled cushion as the suspension reaches full extension.

Can this shock be adjusted or repaired?

Yes, this shock is fully rebuildable and re-tunable. This means you can service it if needed or adjust the damping characteristics to suit your specific driving needs or modifications.
