DVA Mechanics makes three mounting hardware kits for the Mercedes-Benz Sprinter roof, and the right one depends on what you're bolting to. Each kit covers 8 mounting points and installs into an existing track or T-slot channel, so nothing gets drilled into the roof. Pick the package that matches your setup below. Not sure which one you need? Call us at (920) 249-7744 and we'll sort it out before you order.
Which Kit Do I Need?
- Putting DVA DualTrack-T crossbars on factory Sprinter roof rails? Get the 25 mm × 25 mm T-Slot Hardware Kit.
- Need a heavy-duty M8 mount for the factory Sprinter roof track only? Get the 25 × 25 × 5 mm Slider + M8 Kit.
- Want one M8 mount that works on OEM tracks, LoadSpan-T and DualTrack-T? Get the 25 × 25 × 3 mm Universal Slider + M8 Kit.

The Three Packages
25 mm × 25 mm T-Slot Hardware Kit
The original kit. The T-slot bolts slide into the channel of a Sprinter's factory longitudinal roof rails and give DVA's DualTrack-T Cross Bar Rail Kit a solid mounting interface, so you keep the factory rails and add a modular L-Track and T-slot crossbar system on top. Enough hardware for two DualTrack-T bars. You don't need this kit for standard DualTrack-T installs or for installs onto DVA's LoadSpan-T rails; those include their own hardware.
In the box: 8 × 25 × 25 mm T-slot bolts, 8 × washers, 8 × nuts
25 mm × 25 mm × 5 mm Slider + M8 Hardware Kit
Thicker 5 mm sliders sized specifically for the channel profile of the factory Sprinter roof track. They slide in and give you a sturdy M8 mounting point for roof accessories without drilling. Built for the OEM track only; this one won't fit LoadSpan-T or DualTrack-T.
In the box: 8 × 25 × 25 × 5 mm sliders, 8 × M8 bolts, 8 × M8 washers
25 mm × 25 mm × 3 mm Universal Slider + M8 Hardware Kit
The most versatile option. The lower-profile 3 mm slider fits the factory Sprinter roof track plus DVA's LoadSpan-T roof tracks and DualTrack-T crossbars, so one hardware standard covers your whole roof.
In the box: 8 × 25 × 25 × 3 mm sliders, 8 × M8 bolts, 8 × M8 washers

Frequently Asked Questions
What's the difference between the 5 mm and 3 mm slider kits?
The number is the slider's thickness. The 5 mm slider is sized for the factory Sprinter roof track only. The thinner 3 mm slider also fits DVA LoadSpan-T tracks and DualTrack-T crossbars.
I'm mounting DualTrack-T crossbars to my factory roof rails. Which kit?
The 25 × 25 mm T-Slot Hardware Kit. It's enough for two DualTrack-T bars.
Do I need any of these for a standard DualTrack-T or LoadSpan-T install?
No. Those kits include their own mounting hardware. These kits are for mounting to factory rails or adding M8 mounting points to a track.
Does it require drilling?
No. Every kit slides into an existing track or T-slot channel.
