Description
EXA PORTAL GEARBOX SYSTEMS FOR GREAT WALL & TANK SERIES
The EXA portal gearbox system is an advanced engineering solution designed for Great Wall and Tank off-road platforms, specifically engineered to maximize ground clearance while optimizing drivetrain gear ratios. This system provides a strategic 109 mm (4.3-inch) lift at the hubs, allowing for the fitment of tires up to 40 inches without increasing the stress on the factory CV axles or differentials. For the Guatemalan market, where diverse terrains range from volcanic mountain tracks to coastal agricultural zones, these portal units offer unmatched mobility for expeditionary and industrial support vehicles operating near Guatemala City and Puerto Quetzal.
Direct B2B procurement through our specialized industrial sourcing hub ensures that global distributors receive factory-certified hardware with comprehensive technical audits. The EXA system utilizes lightweight aluminum alloy housings to minimize unsprung mass, paired with internal gears forged from a specialized molybdenum-titanium alloy for superior torque resilience. Every kit includes a high-performance disc braking system and is pre-configured for central tire inflation systems (CTIS), ensuring technical compliance with international fleet maintenance standards. Professional technical documentation and end-of-line quality verification are provided for every international export batch.
Global Sourcing Compliance Summary:
- Verified industrial banking gateways for secure B2B settlements between China and Central American hubs.
- Strict technical alignment of financial flows with factory serial numbers and ISO 9001 compliance.
- Risk mitigation via escrow-ready structures and multi-currency international trade frameworks.
- High-speed logistics handling for industrial components to minimize fleet downtime in specialized sectors.
Maintaining supply chain transparency is essential for the legal integration of high-value automotive components into professional fleets. We provide verified technical sourcing for special machinery and drivetrain assets, ensuring that all metallurgy affidavits and origin certificates are processed for swift import clearance. Each portal unit is dispatched with a technical validation affidavit, confirming that the gear tolerances and housing structural integrity meet industrial load ratings. This data-driven approach allows procurement managers to secure reliable assets for the most demanding technical projects in the Latin American market.
Technical Executive Summary:
Industrial Portal Gearboxes by EXA for Great Wall Tank 300 / Poer. Ground clearance increase: 120 mm. Gear reduction ratio: 1.67:1. Housing material: High-grade Aluminum Alloy. Features: Integrated CTIS preparation and performance disc brakes. System weight: 150 kg per set. Condition: New/Factory direct. Tire compatibility: up to 40 inches.
Technical integration of the EXA portal system into Guatemalan commercial fleets is supported by our specialized engineering team. We provide full consultation regarding sensor calibration and suspension geometry alignment for 4WD vehicles operating in mountainous volcanic regions. Utilizing synthetic lubricants with high thermal stability ensures that the portal gears operate without cavitation during prolonged low-speed technical climbs. Procurement managers can explore our industrial components catalog for scheduled maintenance kits and bearing assemblies.
Operational safety in specialized sectors depends on the mechanical resilience of the hub-reduction gears. The EXA portal units facilitate an institutional reduction in drive-line torque load, effectively moving the stress points to the portal unit itself. This ensures that the main transmission and axles operate within their engineered limits even on oversized tires. Direct sourcing of drivetrain components through our verified supply chain provides a reliable bridge to high-output industrial capacity in the PRC.

Procurement managers often inquire: "What is the total landed cost for a professional portal system under CIF or DDP terms in Guatemala?". To facilitate precise institutional budgeting, we have developed a logistics estimator for high-value industrial cargo reaching major regional hubs. This calculation accounts for the entire journey from factory gates in the PRC to final discharge at Puerto Quetzal. Utilizing direct maritime routes ensures a balanced approach between cost-efficiency and technical supply chain reliability.
Logistics Estimator (Updated: January 2026)
Shipping Route: PRC Hub -> Shanghai Port -> Puerto Quetzal (Guatemala) -> Guatemala City.
International Freight: from $1.55/kg (Industrial Promo Rate).
Regional Handling: CIF / DDP options available upon TDS finalization.
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 Central American 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 attachments.
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 industrial 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 gearboxes represent the definitive solution for converting GWM Tank 300 or Poer vehicles into institutional-grade off-road assets without compromising drivetrain reliability. The molybdenum-titanium alloy gears are essential for managing 40-inch wheel loads in mountainous Latin American terrains. Only direct factory audits and ultrasonic housing verification ensure your fleet maintains peak operational readiness in Guatemala."

Technical FAQ: EXA Portal Sourcing
How much will the ground clearance increase?
The EXA portals provide a pure axle lift of 109 mm. Combined with 37-inch tires, the total clearance gain is approximately 150 mm.
Is a main differential gear change required?
No. The 1.67 reduction ratio within the portal units compensates for oversized tires, unloading the factory drivetrain components.
Is CTIS included in the base B2B package?
Yes, our industrial sets include the central inflation hardware, including a 4L reservoir and reinforced plumbing as standard.
What is the gearbox warranty cycle?
The housings and internal gears are covered by a 12-month industrial limited warranty for corporate procurement batches.
How do portals perform in high-heat zones?
Units are tested in ambient temperatures up to +60°C. The aluminum alloy housing ensures superior heat dissipation for constant use.
Are international trade documents provided?
Yes. We supply full documentation, including Bill of Lading and Certificate of Origin for Guatemalan SAT customs clearance.
What wheel specifications are required?
R17 rims or larger with a positive offset of ET +30 or more are mandatory for correct gearbox clearance inside the wheel rim.
Is gear hardness verified during QC?
Absolutely. Technical audits include Rockwell hardness verification for the Mo-Ti alloy gears and ultrasonic casting inspection.
