PD+ Version Feature Adjustment

PD+ version shock absorber function adjustment

The shock absorber can adjust the rebound damping in stages according to different driving modes, with the following ranges for the number of rebound stages in each mode:
Urban road section: The number of rebound cycles is between -21 and -30.
Off-road section: Rebound count ranges from -11 to -20.
Competition or desert stage: the number of rebound segments ranges from -1 to 10.

Note: When tightened fully in the clockwise direction, the damping force is at its maximum, and the gear position is 0.

GP version Function Adjustment

Functional adjustment of the GP‑version shock absorber

The shock absorber can adjust compression and rebound damping in discrete stages according to different driving modes, with the following ranges of stages for each mode:
Off-road mode (cross-country/desert): Compression stroke range is -1 to -3, rebound stroke range is -4 to -6.
High-speed control mode: compression stroke count: -4 to -6, rebound stroke count: -1 to -3
Comfort Mode: Compression stroke range is -7 to -9, rebound stroke range is -7 to -9.

Note: When tightened fully in the clockwise direction, the damping force is at its maximum, and the gear position is 0.

Competitive Mode Feature Adjustment

Low-speed damping adjustment

Controls the damping force of compression. Controls body roll.
(-5)-(-10) section: Competition Mode (Extreme Off-Road, Racing)
(-10)-(-18) section: Normal mode (city, standard off-road)
(-18)-(-25) section: Comfort mode (city, climbing)

Low-speed adjustment method
Use the DN‑specific adjustment tool to make the setting: turn clockwise toward the “+” mark all the way to close, then turn counterclockwise toward the “_” mark until you reach the desired position.

Competitive Mode Feature Adjustment

High-speed damping adjustment

At high speeds, it effectively cushions large impacts from vehicle jumps. It features an adjustable force range and a wide application scope.

High-speed adjustment method
Use a 17mm socket wrench to adjust: turn counterclockwise toward the “–” mark for loosening, and clockwise for tightening.
Rotating in the direction of the “+” sign increases stiffness, allowing you to adjust both comfort and firmness according to road conditions.
(-8)-(-13) Section: Competition Mode (Extreme Off-Road, Racing)
(-13)-(-18) section: Normal mode (city, standard off-road)
(-18)-(-25) section: Comfort mode (city, climbing)
