Notice

When the product leaves the factory, the professional technician has made corresponding air pressure adjustment for the shock absorber. Because the shock absorber is filled with high pressure nitrogen, it is dangerous to adjust at will.

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.


Product features

  • 1.The product is a spring oil-air hybrid shock absorber.
  • 2.Built-in air reserve chamber, spring preload and precise adjustment function can show lasting rebound performance, excellent support and fatigue resistance even in the harsh road sections with heavy load and frequent bumps
  • 3.The damper and spring designed for long durability (more 1 million)

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
