Frequently Asked Questions

Which AST components does this tool fit?
Match the tool profile and diameter to the exact AST locking ring or adjustment component. Similar-looking rings can require a different wrench.

Can the tool be used while the suspension is loaded?
Follow the current AST service procedure. Relieve load as directed before turning a spring perch or locking ring, and never work under an unsupported vehicle.

Is this tool included with every AST suspension kit?
Included tools vary by kit. Check the exact kit contents before buying a separate replacement or additional wrench.
