This product is not permitted to be fitted in vehicles operating on normal roads.

The damping setting and spring rate for this product is different from the vehicle's original shock absorbers. Any shock absorbers can be disassembled completely to change the damping setting.

Disassembling the shock absorber also offers a chance for inspection and service to the shock. However, disassembling of the shock absorbers can only be performed by D2 certified professional technicians.

For detailed information about disassembling service, wages, and time required, please contact your local D2 dealers.

• This product contains high-pressure gas inside. Do not attempt to disassemble this product or put it in the vicinity of fire to avoid the risk of serious explosion. Do not install this product if it is found having been disassembled before.
• This product has been designed with reinforcements to be used in vehicles operating on terrain. In addition, this product cannot be modified for any reason.

• If the upper holder has been turned with over-torque during removal or installation, the bolt in the shock may be loosened. In addition this may cause damage to the product.

• When removing or tightening bolts on the upper holder, do not use any tool to clamp the cylinder at the top of the shock or clamp the shock body onto the place where there are treads to avoid scratching.
• Do not bump with force and/or impact the shock body (e.g. dropping this product)
• If the cylinder has been scratched, the seal may be damaged and cause the shock to leak.
• To increase the product durability and performance, the outer diameter usually is greater than that of the original shock absorber. Some shock absorbers do not
  contain boots due to space limitation for a boot. For the product without a boot, we suggest the surface of the cylinder be cleaned regularly and check the shock periodically to ensure the performance and increase the lifespan of the product.
• Please note that dirt and small pebbles may damage the cylinder.

• When installing this product, the operator shall wear gloves to avoid the risk of hand injury.
• The upper holder used in this shock must be D2 original component. This shock absorbers may not be compatible with the upper holder of other brands.
• D2 shall not take any liability for damage to the shock or accidents that are caused by connecting the upper holder of other brands with this shock.
• Be sure to observe local relevant vehicle regulations about usage of adjustable shock absorbers. (For example, height limit, headlight ground clearance limit)
• D2 shall hold no liability for any violation against local vehicle regulations or laws.
• According to the installation instructions, avoid uneven road surface and driving at low speed.
• Ensure that components of the product are not loosened or oil is not leaking.
• To tighten all components with specified torque periodically.
• When a suitable height is determined it shall be tested and calibrated on straight line.
• The vehicle should go to a specified workshop or a commissioned vehicle calibration center to adjust the calibration.

• TO remove the nut at the top by depressing the spring with the spring depression tool.
• When taking out the nut at the top, make sure the spring is depressed and is not in contact with the upper and lower holders.
• When releasing the spring depression tool, pull the spring out of the shock evenly and carefully.
• Do not re-use the used nut removed from the cylinder.

• The adjustable damper uses a hollow cylinder. To protect against damage, be sure to note the torque applied for turning.
• When tightening the nut at the top, be sure the tool does not contact the adjustment point at the top.
• After installation, ensure using an adjustment level so that the adjustment scale is truly in a clockwise direction. Adjust it with the adjustment level.
• Lowering the vehicle with lowest setting of the spring holder may damage the body of the vehicle.

• The shock absorber will be coated with a lubricant at factory to protect against rusting, which is not leaked fluid.

• After the height is adjusted, be sure that the spring holder has been tightened.
• Drift or small pebbles may attach to the spring holder has been tightened.
• Dirt or small pebbles may attach to the spring holders, which may also cause damage.
• Dirt or small pebbles may attach to the threads of the spring holders, which may cause damage if adjustment is made without clearing them.

• If the component cannot be turned smoothly, add some lubricant. To prevent sticking of the spring holder, we suggest that the components be checked and serviced periodically.

• After putting on tires, measure the distance from the tire center to the fender of the vehicle (as shown in illustration and make sure the distance meets the following data:

• When adjusting according to driving a specific vehicle (for example, on race track), it is possible to make an asymmetrical setting for the right and left dampers.
• If it is uneven longitudinally, adjust only the front or rear damper.
• In some vehicles, you may need to remove the interior components before making the adjustment.
• When adjusting the damper, you may wish to modify the interior equipment of the vehicle.
• When it is necessary to adjust the damper, you may need to drill holes in the interior of the vehicle.
