The BJ30 Offroad Retrofit transforms Beijing Offroad’s compact SUV into a fully equipped adventure vehicle. Designed for enthusiasts who demand both utility and style, this package includes four critical components: Fixed Side Steps, Roof Platform with Integrated Side Ladder, Electric Running Boards, and a High-Performance Antenna System. Each element combines rugged durability with intelligent engineering to conquer challenging terrains while maintaining the BJ30’s urban sophistication.
1. Fixed Side Steps: Robust Protection & Convenient Access
Material & Construction
-
Constructed from aerospace-grade 6061-T6 aluminum alloy with a black powder-coated finish for corrosion resistance.
-
Reinforced steel mounting brackets withstand up to 300kg dynamic load (200kg static).
-
Non-slip textured surface with diamond-pattern treads ensures secure footing in wet/muddy conditions.
Design Features
-
Low-Profile Integration: Maintains ground clearance (adds only 40mm height) while providing 320mm width for optimal foot placement.
-
Structural Reinforcement: Tubular design with internal ribbing prevents deformation during rock crawling or side impacts.
-
Terrain Adaptability: Angled edges deflect debris, and drain holes prevent mud/water accumulation.
Installation & Compatibility
-
Direct bolt-on replacement for factory side skirts using OEM mounting points (no drilling required).
-
Compatible with all BJ30 trims (2022–present), including models with factory rock rails.
Use Case Benefits
-
Enables easier roof rack access when combined with the roof platform ladder.
-
Acts as a partial barrier against trail obstacles (rocks, branches) to protect door panels.
2. Roof Platform with Side Ladder: Modular Cargo & Expedition Readiness
Platform Specifications
-
Dimensions: 1400mm (L) × 1100mm (W) × 50mm (H); weight capacity 150kg (dynamic)/300kg (static).
-
Laser-cut aluminum slats with hexagonal perforations reduce wind noise and allow tie-down flexibility.
-
Integrated LED light channels (optional) for nighttime cargo management.
Ladder System
-
Foldable 3-step aluminum ladder with 75° incline for ergonomic climbing.
-
Automatic locking hinges deploy with one-handed operation; folds flush against the platform when stowed.
-
Weight rating: 120kg per step; rubberized contact points prevent paint damage.
Engineering Highlights
-
Aerodynamic Profile: Wind tunnel-tested to minimize drag (adds only 0.02 Cd to vehicle coefficient).
-
Water Drainage: Channels direct runoff away from the sunroof/roof seams.
-
Security: Lockable crossbars deter theft of mounted equipment (e.g., spare tires, Pelican cases).
Practical Applications
-
Supports rooftop tents, jerry cans, or recovery gear while maintaining a low center of gravity.
-
Ladder enables safe loading/unloading without relying on tire steps or door frames.
3. Electric Running Boards: Smart Entry for Offroad & Urban Use
Deployment Mechanism
-
Motorized arms deploy in 0.8 seconds with a 40° downward angle; retract fully under chassis when inactive.
-
IP67-rated actuators withstand submersion in 1m water for 30 minutes.
User Experience
-
Auto-Sensing Triggers: Deploys upon door unlock via key fob or proximity sensor; retracts when doors lock or vehicle exceeds 15 km/h.
-
Override Modes: Manual control via cabin switch for wash mode or technical terrain.
Durability Features
-
3mm thick 304 stainless steel steps with anti-skid rubber inserts.
-
Self-diagnostic system alerts via dashboard if obstruction or motor fault is detected.
Performance Advantages
-
Improves accessibility for lifted suspensions (up to 2” over stock) without compromising breakover angle.
-
Silent operation with 65dB noise level during deployment.
4. High-Gain Antenna System: Reliable Communication
Technical Specifications
-
Frequency Range: 144–148 MHz (VHF) / 430–440 MHz (UHF) for amateur radio/GMRS compatibility.
-
Gain: 6dB (VHF), 8dB (UHF); max power handling 50W.
-
Construction: Carbon fiber whip with stainless steel base; length-adjustable from 60cm to 1.2m.
Mounting & Integration
-
Magnetic or permanent bracket options (roof/door hinge mounts).
-
Coaxial cable routed through factory grommets to minimize interior modifications.
Operational Benefits
-
Extends signal range to 15–20km in open terrain (vs. 5km for handheld units).
-
Flexible design prevents damage when brushing against tree branches.
Synergistic Advantages of the Full Retrofit Package
-
Weight Distribution: Combined weight under 45kg (excluding roof cargo) avoids significant MPG penalties.
-
Aesthetic Cohesion: Matte black finishes and angular designs complement the BJ30’s factory styling.
-
Turnkey Adventure Prep: Eliminates aftermarket compatibility issues with pre-engineered bolt-on solutions.
Ideal For:
-
Overlanding setups requiring quick access to roof-stored gear.
-
Urban users seeking rugged visual upgrades with retained pavement manners.
-
Radio operators needing dependable comms during remote travel.
This retrofit package elevates the BJ30 from a capable crossover to a serious offroad contender without sacrificing daily drivability. Each component undergoes 2,000km of mixed-terrain validation to ensure longevity under real-world conditions.
