FAQ
What thread does this shock extension use?9/16-18 UNF.
How much length does this extension add?2 inches.
What material is this extension made from?Aluminum.
Is this extension vehicle-specific?No. It is a universal hardware component sized by thread and length; confirm the shock's thread matches before ordering.
Can this extension be used on any QA1 shock?Only if the shock uses a matching 9/16-18 UNF thread; verify before ordering.
Does adding this extension change ride height?It changes the shock's effective mounted length, which can affect installed ride height; verify total length fits the application.
Is a jam nut included?QA1's listing for this part number does not itemize a jam nut as included; verify separately.
Will this extension work with any shock brand?Confirm the mating shock uses the same 9/16-18 UNF thread; this is not guaranteed across all brands.
Installation Instructions
QA1 does not publish a vehicle-specific torque value for this hardware; use general threaded-fastener practice and the shock manufacturer's guidance.
- Confirm the shock's mounting thread is 9/16-18 UNF before ordering.
- Thread the extension onto the shock body or mount as designed.
- Secure with a jam nut or per the shock manufacturer's locking method.
- Verify total assembled length fits the available chassis travel before final installation.
