Tech Insight

The reservoir top cap plays a critical role in:

• Sealing the nitrogen chamber
• Maintaining consistent internal pressure
• Preventing oil and gas contamination
• Supporting long-term durability under high heat and pressure

When servicing a shock, always inspect:

• Cap threads
• O-ring sealing surfaces
• Internal snap ring grooves
• Nitrogen valve condition

Any damage to the cap sealing surface can lead to pressure loss and inconsistent damping performance.
