- Nitrogen gas-charged twin-tube design: the Excel-G is built to restore the vehicle's original ride control, stability, and handling rather than change it.

- Triple-lip fluid seal: designed to reduce the chance of oil and gas leaking out.
- Thick strut bodies and brackets: minimize flex to help maintain correct alignment across driving conditions, supporting the electronic safety systems that depend on the suspension.
Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement. If worn rear shocks are behind excessive bounce, nose dive, or poor stability, this unit replaces them.
