When sourcing Off-Road SUVs, buyers must prioritize drivetrain capabilities and chassis strength. Ensure the vehicle features a True 4WD (Four-Wheel Drive) system with low-range gearing for high-torque requirements. Key technical specs include a minimum ground clearance of 210mm, approach angles above 30 degrees, and departure angles above 25 degrees. For heavy-duty use, verify the presence of locking differentials (front, center, or rear) and a body-on-frame (ladder frame) construction, which provides superior torsional rigidity compared to unibody designs.
