LoadSpan™ Load-Spreading Roof Rails for Mercedes-Benz Sprinter
Full-Length Load-Distributing Rail System with Integrated Native L-Track for (2019–Present) 144", 170", and 170" Extended Mercedes-Benz Sprinter vans.
LoadSpan™ is a structural backbone engineered to spread load evenly across the entire roofline—reducing point stress and maximizing dynamic stability. With an integrated native L-Track channel, LoadSpan™ is the only front-to-back Sprinter rail system on the market that combines continuous load distribution with full L-Track accessory integration.
- Fits: Mercedes-Benz Sprinter 144" / 170" / 170" Extended (2019–Present)
- Install: Direct mount to factory roof hard points — no drilling
- Design: Rigid interlocking sections for full-length load distribution
- System: Integrated L-Track channel for universal accessory mounting
Available Lengths
| Sprinter Version | Rail Length (in) | Rail Length (cm) | Weight (kg) | Weight (lb) |
| 144" | 118.3 in | 300.6 cm | 3.8 kg | 8.4 lb |
| 170" | 158.5 in | 402.6 cm | 5.1 kg | 11.3 lb |
| 170" Extended | 173.5 in | 440.6 cm | 5.6 kg | 12.3 lb |
OEM Rails vs. LoadSpan™
OEM roof rails are engineered with a relatively compliant profile—meaning under real load they can deflect. That deflection matters: when weight is applied through a bracket, crossbar, or tie-down, the rail can bend locally and the force is transferred into the roof primarily near the load point. The result is a concentrated load path, higher localized stress at the roof interface, and less predictable stability under vibration, leverage, and shifting loads.
LoadSpan™ is engineered around stiffness and continuity. Its front-to-back rail architecture resists localized bending and instead distributes forces along the rail and into multiple factory roof mounting locations. Rather than allowing the rail to act like a spring at the load point, LoadSpan™ creates a shared load path across the full rail length for more stable, controlled roof loading.
LoadSpan vs. Other Sprinter Rail Systems
| Feature | LoadSpan™ | Typical Aftermarket |
| Rail Design | Rigid interlocking sections (2–3 per side) | Segmented with flex points |
| Load Distribution | Spreads across entire roofline | Concentrated at mount points |
| L-Track Integration | Native full-length channel | None or requires adapters |
| Drilling Required | No — uses factory hard points | Often requires drilling |
Why LoadSpan™
- Continuous load-spreading backbone: Rails distribute forces across the roofline instead of concentrating stress at isolated attachment points.
- Integrated native L-Track: Full-length L-Track channel enables direct attachment of standard rings, studs, anchors, and tie-down hardware without adapters.
- M6 / M8 slider compatibility: Supports accessories designed for OEM and third-party rails using standard M6 and M8 slider hardware.
- Maximum tie-down flexibility: Combine rapid-adjust L-Track accessories with rigid bolted mounts on the same rail system.
- No drilling required: Mounts directly to factory roof hard points for a secure installation without modifying the vehicle structure.
- Purpose-built for Sprinter geometry: Premium, integrated fit engineered specifically for Mercedes-Benz Sprinter rooflines.
- Designed for long-term structural stability: Optimized for vibration resistance, load cycling, and fatigue over extended service life.
L-Track Accessory Compatibility
LoadSpan uses industry-standard L-Track channels, compatible with thousands of existing accessories:
- DVA Accessories: Mounting clamps, light mounts, Starlink mounts, recovery board carriers
- Universal L-Track Fittings: Single studs, O-track rings, tie-down anchors, sliding mounts
- Cargo Systems: Most L-Track compatible cargo nets, straps, and tie-downs
Already own L-Track accessories? They'll likely work with LoadSpan. Contact us to verify compatibility.

Engineering Note: LoadSpan™ is designed to optimize how loads are transferred into the vehicle, not to inflate published load ratings. Final allowable load is governed by Mercedes-Benz roof specifications and vehicle configuration.
Frequently Asked Questions
Does this fit my Sprinter?
LoadSpan fits all 2019+ (VS30) Mercedes-Benz Sprinter vans — 144", 170", and 170" Extended wheelbases, all roof heights (Standard, High, Super High). Not compatible with 2018 and earlier (NCV3) models.
Do I need to drill into my roof?
No. LoadSpan mounts to factory roof hard points with no drilling required.
What's the load capacity?
Load capacity is determined by your Mercedes-Benz roof rating, not the rails — LoadSpan exceeds these limits by design:
Standard Roof: 660 lbs dynamic / ~1,320 lbs static
High Roof: 330 lbs dynamic / ~660 lbs static
Dynamic = while driving. Static = parked. Capacity includes the weight of the rails themselves (~8–12 lbs depending on length). Source: Mercedes-Benz Sprinter Operator's Manual, pages 151 and 286.
Can I mount crossbars to LoadSpan?
Yes. The integrated L-Track channel accepts standard crossbar feet, and the included M8 sliders work with most bolt-on crossbar systems.
Will this work with my roof rack / cargo box / solar panels?
LoadSpan's continuous L-Track channel supports most standard accessories including crossbars, awnings, solar panels, cargo boxes, and ladder racks. Contact us to verify your specific setup.
How long does installation take?
Most installations take 60–90 minutes with basic hand tools.
I have a camper conversion — will this work?
Yes. LoadSpan is ideal for camper builds requiring flexible mounting points. The full-length L-Track lets you position accessories anywhere along the rail.
What's the difference between the 144", 170", and 170" Extended versions?
Each version is cut to match your Sprinter's wheelbase. The rails span the full length of your roofline — select the version that matches your van.
What's the warranty?
LoadSpan is backed by DVA Mechanics' warranty against manufacturing defects. See full warranty details.
Can I return it if it doesn't fit my setup?
Yes. Unused products can be returned within 30 days. See return policy.
