Frequently Asked Questions About Volvo VNL Gen III Shock Absorbers

Will these shock absorbers fit my 2018-2024 Volvo VNL truck?

Yes, these shock absorbers are specifically designed for Volvo VNL Generation III models from 2018 to present (2024). They are engineered to match the exact mounting points and specifications of the Gen III chassis. However, they are NOT compatible with pre-2018 VNL models (Gen I or Gen II) due to different mounting configurations and dimensions. Always verify your truck's VIN and model year before ordering to ensure proper fitment.

What's the difference between OEM and aftermarket shock absorbers for my VNL?

OEM shocks are manufactured to Volvo's exact specifications and typically carry a higher price point but guarantee perfect fit and performance. Aftermarket options from reputable brands like Gabriel, Monroe, or Bilstein often provide comparable or enhanced performance at a lower cost. Key differences include warranty coverage (OEM usually 1-2 years, aftermarket varies), ride stiffness options, and price points. Many drivers report aftermarket heavy-duty shocks lasting longer under severe service conditions, while OEM shocks provide the factory-intended ride quality.

Can I install these shock absorbers myself, or do I need special tools?

While shock absorber replacement is possible for experienced DIY mechanics, it requires specific tools including a spring compressor (for front shocks), torque wrench, and proper jack stands rated for commercial vehicles. The front shocks typically take 2-3 hours per side, while rear shocks average 1-2 hours per side. Common challenges include accessing upper mounting bolts in tight spaces and safely compressing springs. Most customers recommend professional installation for safety reasons, especially if you lack commercial truck experience or proper lifting equipment.

How do I know when my VNL shock absorbers need replacement?

Common signs include excessive bouncing after hitting bumps (more than 2-3 oscillations), visible oil leaking from the shock body, uneven tire wear patterns, nose-diving during braking, or a noticeably rougher ride quality. Physical inspection should reveal any bent shafts, damaged bushings, or corrosion. Most VNL drivers report needing replacement between 150,000-250,000 miles under normal highway conditions, though severe service applications may require replacement as early as 75,000-100,000 miles.

Should I replace all four shock absorbers at once or can I do them individually?

While you can technically replace shocks individually, it's strongly recommended to replace them in pairs (both fronts or both rears) at minimum. Mismatched shock absorbers can cause uneven ride height, poor handling characteristics, and accelerated wear on the newer shock. For optimal performance and ride quality, replacing all four ensures balanced suspension performance. Many fleets follow a full-set replacement schedule to maintain consistent handling across their vehicles and simplify maintenance tracking.
