Description
EXA High-Performance All-Wheel Drive Portal Gearbox System
The EXA industrial portal gearbox system is a definitive drivetrain engineering solution for Great Wall and Tank 4x4 platforms, designed to maximize operational ground clearance while maintaining powertrain integrity. For procurement departments serving the heavy industry and maritime sectors in Ras Al-Khair, Saudi Arabia, this system provides a critical 109 mm (4.3-inch) axle lift, enabling the deployment of 40-inch wheel configurations on industrial support fleets. By utilizing hub-reduction technology with a 1.67:1 ratio, the system effectively unloads the factory differentials and half-shafts, significantly increasing the mean time between failures (MTBF) in harsh desert environments. The integration of high-grade molybdenum-titanium alloy gears ensures that the assembly can withstand vertical stress loads of up to 40 tonnes, meeting the highest technical requirements for off-road industrial use.

Direct B2B procurement through ChinaCar.pw facilitates a streamlined path for global special machinery sourcing, focusing on technical transparency and OEM-tier quality control. The EXA system is engineered for thermal resilience, operating efficiently in ambient temperatures up to +60°C, a prerequisite for the KSA industrial sector. Each kit is supplied as a comprehensive conversion package including high-ventilation disc brakes and integrated Central Tire Inflation System (CTIS) preparation. Our commitment to supply chain compliance ensures that every international export batch is accompanied by metallurgy affidavits and end-of-line dynamometer test logs, providing the legal and technical assurance required for large-scale corporate fleet integration.
Global Sourcing & Compliance Summary:
- Verified industrial banking gateways for secure B2B settlements between China and Middle Eastern hubs.
- Strict technical alignment of financial flows with factory serial numbers and ISO 9001 quality audits.
- Risk mitigation via escrow-ready payment structures and multi-currency international trade frameworks.
- High-speed industrial logistics solutions to minimize downtime in petrochemical and infrastructure projects.

Procurement managers often ask: "What is the total landed cost for a remanufactured portal power unit under CIF or DDP terms in the GCC market?". To facilitate institutional planning, we have developed a logistics estimator for industrial LCL cargo reaching the Port of Ras Al-Khair. This calculation accounts for the journey from factory gates in the PRC to final technical discharge at your industrial hub. Utilizing direct maritime routes ensures a balanced approach between technical reliability and technical supply chain speed.
Logistics Estimator (Updated: January 2026)
Shipping Route: PRC Hub -> Shanghai Port -> Port of Ras Al-Khair (KSA) -> Local Facility.
International Freight: from $1.55/kg (Industrial Promo Rate).
Regional Handling: Custom CIF / DDP options provided upon TDS approval.
Note: Final landed cost is calculated strictly after technical documentation finalization. Pricing is subject to currency fluctuations, cargo density, and current carrier surcharges.
Technical compliance and data-backed sourcing are the foundations of our partnership with Middle Eastern industrial firms. We provide comprehensive technical dossiers, including Certificates of Origin and metallurgy affidavits for the molybdenum-titanium internal components. Our secure financial frameworks facilitate transparent transactions, ensuring a robust bridge between global capital and Chinese high-output industrial capacity. Professional procurement teams can rely on our expertise in supply chain risk mitigation for high-value drivetrain assets.
Global B2B / B2C Settlement Protocol
International transaction security in 2026 is maintained through the integration of verified industrial banking hubs, SWIFT settlement structures, and comprehensive trade compliance documentation. We utilize dedicated infrastructure for the procurement of high-value drivetrain systems for both corporate entities and individual professional buyers. This guarantees total legal transparency and protection against supply chain disruptions. Rigorous financial auditing ensures that all procurement flows meet global trade compliance and anti-money laundering standards.
"EXA portal systems represent the definitive solution for converting GWM Tank 300 or Poer vehicles into institutional-grade industrial assets without compromising axle durability. The molybdenum-titanium alloy gears are essential for managing 40-inch wheel loads in high-ambient Saudi industrial environments. Only direct factory audits and ultrasonic housing verification ensure your fleet maintains peak operational readiness in Ras Al-Khair."

Technical FAQ: Industrial Portal Sourcing
How much will the axle lift increase?
The EXA portal units provide a clean axle lift of 109 mm. When combined with 37-inch industrial tires, the total ground clearance gain is approx 150 mm.
Is a main differential swap required?
No. The 1.67 hub reduction ratio compensates for oversized tires, significantly reducing the stress on the factory transmission and differentials.
Is CTIS supported for KSA fleets?
Yes, the industrial kit includes the Central Tire Inflation System hardware, allowing for on-the-fly pressure adjustment in desert terrains.
What is the gearbox warranty cycle?
The housings and internal gears are covered by a 12-month industrial limited warranty for corporate B2B procurement batches.
Do portals perform in extreme heat?
Units are verified for high-ambient operations up to +60°C. The aluminum alloy construction provides superior thermal dissipation for continuous use.
Are international trade documents provided?
Yes. We supply full B2B documentation, including Certificates of Origin and metallurgy affidavits for Saudi customs clearance.
What wheel specifications are required?
Minimum wheel size is R17 with a positive offset of ET +30 or higher to ensure the hub gearbox fits within the wheel rim geometry.
Is gear hardness verified during QC?
Absolutely. Technical audits include Rockwell hardness verification for the Mo-Ti alloy gears and ultrasonic casting inspection for the housings.
