Why Vigor Wins

What Makes Vigor Different

Every Vigor air suspension product is built from the ground up with uncompromising quality. From materials to manufacturing, our products are engineered to outperform — not just meet — OEM expectations. Here’s what sets us apart.

🔩 Reinforced Bead Plate

Crafted from ultra-durable steel, our bead plates feature Cr3+ white zinc plating for over 240 hours of salt spray resistance — 60% longer than typical market alternatives. Designed to resist corrosion even in the harshest environments.


⚙️ Precision Pistons

We use only DuPont® industrial-grade plastic and forged aluminum for piston construction. This delivers high heat resistance, zero deformation under load, and long-term durability — even under severe impact and vibration.

🔧 Grade 8.8 Threads

All threaded components meet Grade 8.8 tensile standards for maximum torque strength and safety. Thread fitment is measured to OEM tolerance for consistent install reliability every time.

 

🛡️ Advanced Rubber Bellows

Our bellows use a proprietary NR/VR blend for enhanced elasticity, flexibility, and fatigue resistance. Rated up to 300 PSI burst pressure and certified for anti-aging and ozone stability for over 500,000 compression cycles.

🔬 OEM-Level Testing Standards

Every Vigor product is tested in-house for pressure fatigue, vibration exposure, and environmental stress. Lab protocols simulate real-road conditions to ensure every unit you receive is ready for performance — not guesswork.


✅ 100% In-House QC

From raw material inspection to final air seal testing, our quality control team inspects each product through 7 checkpoints. No outsourcing. No exceptions. Just certified Vigor strength in every unit.

“I swapped out OEM for Vigor and never looked back — stronger, smoother, and built to last. Worth every penny.”
