The Denza X is one of BYD's larger crossover SUVs sold under the Denza brand, positioned above the everyday BYD SUV lineup. Owners looking to upgrade the entry experience or add finishing touches will find running boards, illuminated sills and small trim pieces here, each sized around the Denza X's body rather than adapted from a different SUV.
The Denza X shares some underlying components with other BYD SUVs, but its exterior dimensions and door cut lines are its own, so aftermarket accessories are built and listed specifically for this model.
Auto-deploying side steps drop down when a door opens and retract while driving, adding a visible upgrade and easier entry for a taller SUV body.
These kits gently pull doors the last few centimeters shut, reducing the force needed to close them fully and cutting down on slammed-door noise.
Running boards typically use an aluminum alloy frame with a non-slip step surface, while soft-close kits are actuator-based add-ons that work alongside the factory latch rather than replacing it. Both are designed for bolt-on installation without permanent modification.
Soft-close kits are aftermarket add-ons; check with your dealer regarding any warranty implications before installation.
Power running boards retract while driving, so they do not reduce usable ground clearance once the vehicle is moving.
Most kits are designed for straightforward bolt-on or plug-and-play installation, though some owners prefer a professional install for wiring-based kits.
