Every now and again someone needs a shock length that isn’t readily available. Here’s how I made a 9×3 shock out of a stock 8.5×2.5.
First thing I had to do was cut and thread a shaft like you can see in the above image.
The second thing I had to do was make a longer rebound needle that sits inside the now longer shaft.
The third step was to machine down the piston bolt to become lower slightly profile to make sure it doesn’t collide with the end of the shock. Here it is below installed onto the shaft.
One final check to make sure there’s no collision at full bottom out.
And there you have it. A custom sized 9×3 shock.
