Adjusting spring length
- The shorter the spring, the greater the elasticity, and is suitable for heavier vehicles.
- The longer the spring, the less elastic it is, making it suitable for lighter vehicles.
- If you often carry people, it is recommended to shorten it
Adjusting spring preload
Notice: It is very important to adjust the spring preload! The size setting will affect your riding comfort
1. After the shock absorber is installed, push the anti-collision body on the main shaft up to the bottom of the main pipe
2. Ride on the vehicle in a normal sitting posture (do not use force to move up and down)
3. Get off the car and observe the distance that the anti-collision body is pushed back, which is the spring preload
4. Normal spring preload is about 15mm
5. If the preload is insufficient (the anti-collision body is pushed back more than 15mm), use the adjusting wrench to turn downward (clockwise) to adjust to increase the spring preload. After adjustment, go back to step 2 and measure again. After adjustment, remember to fix the uppermost fixing plate tightly.

Kyler Outman –
This is not a adjustable shock and is not worth 200 dollars for a set of them. The shrader is however functional and the shock is pressurized with oil.

リアショックを長くして車高を高くしたかったのですが、長すぎて私のバイクには取り付けられませんでした。しかし、異なる長さの商品を豊富に揃えてくださっているのはありがたいです!
