Keep Your Shock Body Sealed and Secure
The 038-00-092 is a Smalley VH-143 internal spiral retaining ring sized for a 1.437 inch housing bore, sold by FOX as a service replacement part. This light-duty, single-turn Spirolox-style ring seats into the internal groove of a 2.0-inch-bore FOX shock body and holds the seal head or bearing assembly in place against axial movement. Because it ships as a raw service component rather than a vehicle-specific kit, this ring is used across FOX's shock rebuild and service parts program wherever a 1.437 inch internal retaining groove of this style is specified.

FAQ
What is the 038-00-092?It is a Smalley VH-143 internal spiral retaining ring sized for a 1.437 inch housing bore, offered by FOX as a shock service and rebuild component.
What size housing bore does this ring fit?It is designed for a 1.437 inch internal housing bore, per the Smalley VH-143 dimensional specification.
What material is this retaining ring made from?Smalley's VH series Spirolox rings of this size are stocked in carbon steel or stainless steel depending on the order; FOX does not publish which specific material variant is used in the service part, so this detail should be confirmed before ordering if material matters for your application.
Does FOX list which shock models use this ring?FOX does not publish a specific shock body or vehicle application list for this retaining ring; it is offered generally as a shock-service component rather than tied to one product line.
How much shear strength does this ring provide?The Smalley VH-143 dimensional spec lists a ring shear strength of 4,740 lb and a groove yield of 2,240 lb.
Is this a snap ring or a spiral ring?It is a spiral-wound Spirolox-style ring, which wraps in a single continuous turn rather than using the split-gap design of a traditional stamped snap ring.
Can this ring be reused after removal?Retaining rings of this type can show fatigue after removal and reinstallation, so replacing it during a shock rebuild is recommended rather than reusing a ring that has already been compressed and released.
Does this part include any other hardware or seals?No, this listing is for the internal retaining ring only; seals, seal heads, and other rebuild components are sold separately.
Install Instructions
