Volvo VNL Gen III Leaf Springs, Hangers & Acc.

Frequently Asked Questions About Volvo VNL Gen III Leaf Springs, Hangers & Acc.

What model years are compatible with these VNL Gen III leaf springs and hangers?

These leaf springs and hangers are specifically designed for Volvo VNL models from 2018 to present (Gen III). They will NOT fit older VNL models from 2003-2017 (Gen II). Always verify your truck's build date and VIN before ordering, as some early 2018 models may still have Gen II suspension components. If you're unsure, check the part numbers on your existing components or contact us with your VIN for verification.

What's the difference between OEM and aftermarket leaf springs for my VNL?

OEM leaf springs are manufactured to Volvo's exact specifications and typically carry a higher price point but ensure perfect fit and ride quality. Aftermarket options can offer significant cost savings (often 30-50% less) and many are built to meet or exceed OEM specifications. Key differences include spring steel grade, arc height consistency, and bushing quality. For trucks under warranty, OEM is recommended. For older trucks or cost-conscious repairs, quality aftermarket brands like Dayton Parts or Triangle provide reliable alternatives.

Can I install these leaf springs myself or do I need special tools?

While leaf spring replacement is possible for experienced mechanics, it requires specific tools and safety equipment. You'll need heavy-duty jack stands rated for commercial trucks, a spring compressor, torque wrench capable of 450-500 ft-lbs, and proper lifting equipment. The job typically takes 4-6 hours per side. Critical safety note: improper installation can lead to catastrophic failure. Many drivers opt for professional installation ($300-500 per axle) to ensure proper torque specs and alignment are maintained.

How do I know when my leaf springs need replacement?

Common signs include: visible cracks or breaks in the leaves, excessive sagging (truck sits lower than normal), uneven tire wear, harsh ride quality, or suspension bottoming out under normal loads. Measure your ride height at the frame rails - if it's more than 2 inches below spec, replacement is likely needed. Also inspect for missing or shifted center bolts, broken spring hangers, or worn bushings. Regular inspection during PM services can catch issues before roadside failures occur.

What's included in a complete leaf spring kit versus individual components?

Complete kits typically include the leaf spring assembly, U-bolts, center pins, and bushings - everything needed for one spring replacement. Individual components are available for specific repairs. Spring hangers, shackles, and equalizers are usually sold separately unless you purchase a comprehensive suspension overhaul kit. For best results and to avoid multiple orders, replace springs in axle pairs and consider replacing worn hangers and bushings at the same time to maximize suspension life and maintain proper alignment.
