High-Load Suspension Application (Reference)

The images below show real-world usage on motorcycle and electric scooter suspension systems.

While this product is primarily listed for mountain bike shock mount applications, these reference examples demonstrate the bolt’s strength, corrosion resistance, and performance under higher load conditions.

Compatibility for non-bicycle applications must be verified by the user.

Important Fitment Note

These bolts are designed for M8 shock mount applications.
Please verify both overall length and shoulder length before ordering to ensure proper fitment.

How to Confirm the Correct Shock Bolt Size

To ensure proper fitment, please check both the overall bolt length and the shoulder length required by your frame.

Step 1: Remove the original shock bolt from your frame.
Step 2: Measure the overall length (from under the head to the end of the threads).
Step 3: Measure the shoulder length (the smooth, unthreaded section).
Step 4: Match your measurements with the size table above.

Important: The threaded length is fixed at 8mm for all sizes.
Selecting the correct shoulder length is critical for proper bearing spacing and smooth suspension movement.
