Their products are tested in extreme environments and have been proven in competitive racing applications, making them ideal for commercial applications that demand durability and consistency.

2. Implement Air Suspension Conversion Kits

Many commercial vehicles can benefit from converting their rigid leaf spring suspensions to air suspension systems. These conversions offer:

• Adjustable ride heights based on load
• Improved ride quality and fuel efficiency
• Lower impact on road infrastructure (ideal for municipalities)

Air suspension kits are especially popular among opérateurs de flotte et commercial vehicle upfitters who need to maintain flexible load conditions, such as refrigerated trucks or emergency response vehicles.

3. Regular Suspension Maintenance Program

Suspension optimization isn’t just about one-time upgrades. A structured maintenance program ensures that systems stay aligned and functional.

B2B Maintenance Checklist:

• Inspect shock absorbers every 20,000–30,000 km
• Check air suspension systems for leaks monthly
• Grease and torque suspension linkages regularly
• Monitor tire wear patterns for suspension issues
• Replace worn bushings, joints, and mounts as needed

These practices are essential for gestionnaires de flotte et service centers servicing multiple commercial vehicles.

4. Load-Specific Suspension Tuning

Suspension systems should be calibrated based on the typical loads carried by the vehicle. Tuning involves adjusting damping rates, spring stiffness, and ride height.

Recommended Tuning Options:

Type de charge	Suspension Tuning Focus
Light/Variable Loads	Adaptive air suspension
Heavy, Consistent Loads	Reinforced leaf springs with heavy-duty shocks
Off-Road Cargo	Long-travel shocks, increased rebound damping
High-Speed Deliveries	Stiff compression damping for stability

G-SAI offers fully-customizable suspension solutions based on load type and terrain. Their engineering team can fine-tune shock absorbers to match exact specifications, ensuring optimal performance.
