Description
EXA High-Output Portal Gearbox System for GWM Tank 300
The EXA portal gearbox system represents the pinnacle of drivetrain engineering for the GWM Tank 300, providing an institutional-grade solution for increasing ground clearance without compromising factory suspension geometry. This conversion kit delivers a strategic 109 mm (4.3-inch) axle lift, enabling the deployment of 40-inch tires on professional exploration and industrial support fleets in Yanbu Industrial City and the Western Province of Saudi Arabia. By utilizing a hub-reduction ratio of 1.67:1, the system effectively multiplies wheel torque while significantly reducing the mechanical load on the main differentials and half-shafts. The precision-cast aluminum alloy housings are engineered for optimal thermal dissipation, essential for high-cycle desert operations under extreme ambient conditions.
Direct B2B procurement via our portal gearbox catalog ensures that international distributors receive factory-certified hardware with comprehensive technical audits. The EXA system features an integrated Central Tire Inflation System (CTIS) and high-ventilation disc brakes, providing total control over tire footprint and stopping power in technical off-road environments. Our supply chain compliance protocol includes Rockwell hardness verification of the Molybdenum-Titanium alloy gears and ultrasonic casting inspections at our PRC hub. This rigorous engineering approach allows global procurement departments to secure verified drivetrain assets with a documented technical history and long-term operational resilience.
Technical Procurement & Compliance:
- 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 standards.
- Risk mitigation via escrow-ready payment structures and multi-currency international trade frameworks.
- High-speed industrial logistics solutions to minimize downtime in infrastructure and exploration projects.
Operational safety in heavy-duty off-road sectors depends on the mechanical stability of the hub-reduction units. EXA portal systems facilitate a strategic reduction in unsprung weight, improving suspension responsiveness on uneven terrain. We provide comprehensive global sourcing for special machinery and specialized drivetrain components, ensuring all units meet the load-rating requirements of Saudi industrial projects. Each kit is dispatched with metallurgy affidavits and technical certificates, facilitating seamless integration into professional fleets managed by major petrochemical and construction firms in the KSA.
Technical Executive Summary:
Industrial EXA Portal Gearboxes for GWM Tank 300. Axle lift: 109 mm (4.3"). Reduction ratio: 1.67:1. Housing: Precision Aluminum Alloy. Gears: Molybdenum-Titanium Alloy. Features: Integrated CTIS support and performance disc brakes. Load Rating: 40 tonnes destructive resistance. Professional B2B sourcing ready for the Yanbu Industrial sector.
For technical departments matching portal revisions with existing chassis, we provide specialized industrial components and service kits. The EXA portal hub design ensures that half-shaft operating angles remain near factory parameters, even at full articulation. This critical feature eliminates the vibrations and accelerated wear typically associated with extreme suspension lifts. Every international dispatch is protected by reinforced export crating and climate-controlled storage protocols during maritime transit to the Yanbu King Fahd Industrial Port.

Procurement managers often inquire: "What is the total landed cost for a professional hub-reduction portal system under CIF or DDP terms?". To ensure full transparency, we have developed a logistics estimator for industrial LCL cargo reaching the Port of Yanbu. This calculation accounts for the journey from factory gates in the PRC to the final technical discharge at your regional industrial hub. Utilizing direct maritime routes ensures a balanced approach between cost-efficiency and technical supply chain reliability.
Logistics Estimator (Updated: January 2026)
Shipping Route: PRC Industrial Hub -> Shanghai Port -> Port of Yanbu (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 seasonal logistical 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 Yanbu’s high-ambient desert environments. Only direct factory audits and ultrasonic housing verification ensure your fleet maintains peak operational readiness in Saudi Arabia."

Technical FAQ: Industrial Portal Sourcing
How much will the axle lift increase?
The EXA portal gearboxes provide a fixed hub lift of 109 mm. When paired with 37-inch industrial tires, the net ground clearance gain is approximately 150 mm.
Is a main differential gear swap required?
No. The 1.67 reduction ratio within the hub units compensates for oversized wheels, effectively разгружая the factory transmission and engine.
Is CTIS supported for Saudi industrial fleets?
Yes, the industrial set includes technical preparation for central inflation hardware, allowing for on-the-fly pressure adjustment in desert terrains.
What is the gearbox industrial warranty?
The aluminum housings and alloy gears are covered by a 12-month industrial limited warranty for corporate procurement batches.
Do portals perform in extreme desert heat?
Units are verified for high-ambient operations up to +60°C. The aerospace-grade aluminum construction provides superior thermal dissipation.
Are international trade documents provided?
Yes. We supply a full documentation set, including Certificate of Origin and metallurgy affidavits for KSA customs clearance.
What wheel specifications are required?
A minimum wheel size of R17 with a positive offset (ET) of +30 or higher is required to house the portal unit inside the rim.
Is gear hardness verified during audit?
Yes. Mandatory technical audits include Rockwell hardness testing of the internal gear sets and ultrasonic casting verification of housings.
