Choosing the Right Sprinter Van Roof Rack

Selecting the perfect roof rack system for your Sprinter isn’t just about fitting something to the roof; it’s about finding the right solution that complements your van’s purpose and your personal style. Different racks offer varying benefits, from carrying capacity to aerodynamic efficiency and ease of installation. Understanding these differences will help you make an informed decision that you’ll be happy with for years to come.

Types of Sprinter Van Roof Rack Systems

Sprinter roof racks generally fall into a few main categories, each with its own advantages:

Crossbars: These are the most basic type, consisting of two or more bars that span the width of the van. They are excellent for carrying modular loads like kayaks, lumber, or bikes, provided you have appropriate mounting accessories. They offer a more budget-friendly option and are relatively simple to install.
Platform Racks (or Luggage Racks): These are full-sized, flat platforms that cover a significant portion of the roof. They are ideal for carrying larger, bulkier items, rooftop tents, or for creating an elevated outdoor living space. Platform racks often provide more tie-down points and a more unified look.
Ladder Racks: Primarily used by tradespeople and contractors, these racks are designed to securely hold ladders and other long, bulky equipment. They are built for strength and durability, prioritizing functionality for professional use.
Specialty Racks: These are designed for specific purposes, such as solar panel mounting systems, water tank carriers, or custom solutions for adventure gear.

Factors to Consider When Choosing

Beyond the type of rack, several other factors are crucial for selecting the best fit for your Sprinter:

Material: Most racks are made from aluminum or steel. Aluminum is lighter and more resistant to corrosion, making it a popular choice for many Sprinter owners, especially those in coastal areas. Steel is generally stronger and more affordable but heavier and more susceptible to rust if not properly treated.
Mounting Method: How the rack attaches to your Sprinter is critical. Options include:
- Rain Gutter Mounts: Older Sprinters might have rain gutters. These racks clamp onto the gutters, offering a secure attachment point without drilling into the roof skin.
- Fixed-Point Mounts: Many modern Sprinters come with pre-drilled, threaded mounting points on the roof. This is the most secure and aesthetically pleasing method, as it uses factory-designed locations.
- Bare Roof Mounts: Some roof rack systems can be installed directly onto the van’s roof skin, often with adhesive and specialized mounting hardware. This requires careful sealing to prevent leaks.
Weight Capacity: Always check the dynamic (while driving) and static (while parked) weight limits of the rack system. Ensure it can support the weight of your intended cargo and any accessories like a rooftop tent. Your Sprinter’s roof itself has a weight limit, so be mindful of that as well.
Aerodynamics: A more aerodynamic rack can reduce wind noise and improve fuel efficiency. Platform racks and some crossbar designs are more streamlined than others.
Ease of Installation: While many racks are designed for DIY installation, some are more complex than others. If you’re not comfortable with drilling, opt for a system that utilizes existing mounting points or explore professional installation.
Compatibility: Ensure the rack is specifically designed for your Sprinter van model year. Sprinter roofs can vary slightly between generations and wheelbases.

Step-by-Step Sprinter Van Roof Rack Installation Guide

The exact installation process will vary slightly depending on the specific roof rack model you purchase. Always refer to the manufacturer’s instructions as your primary guide. This general guide covers common installation methods, particularly for racks that utilize factory mounting points or require drilling into the roof.

Preparation is Key

Before you even think about touching a tool to your Sprinter, proper preparation is essential. This stage ensures accuracy and protects your van.

Read the Instructions: Seriously. Manufacturers spend time and resources creating these guides for a reason. Understand every step before you begin.
Clean Your Van: Thoroughly wash and dry the roof of your Sprinter. Remove any dirt, grime, or wax.
Inspect the Roof: Check for any existing damage, dents, or rust. Address these issues before proceeding.
Gather Tools and Materials: Lay out all your tools and materials as per the checklist above. Ensure you have everything within easy reach.
Map Out Mounting Points: Many Sprinters have pre-drilled mounting holes or mounting points. If yours does, locate them carefully. If you need to drill, use masking tape to mark your intended hole locations precisely. Measure, double-check, and then measure again.

Installation Process (Utilizing Factory Mounting Points – Most Common for Newer Sprinters)

This is the preferred method for many, as it uses the structural integrity designed by Mercedes-Benz.

Locate and Access Mounting Points: Most Sprinters, particularly those equipped for roof racks from the factory, have threaded mounting studs or bosses located along the roof seams. These are often covered by small plastic caps or trim pieces. Carefully remove these covers.
Prepare the Mounting Points: Clean the area around each mounting point thoroughly with rubbing alcohol or acetone to ensure a clean surface for sealant.
Install Brackets: Place the roof rack’s mounting brackets over the factory mounting points. Ensure they are oriented correctly as per your rack’s instructions.
Apply Sealant: Apply a generous bead of high-quality automotive sealant (like Sikaflex 221) around the base of each bracket where it will contact the roof, or directly into the threaded mounting holes if specified by the manufacturer. This is critical for preventing water intrusion.
Secure the Brackets: Fasten the brackets to the Sprinter using the provided hardware (bolts, washers). If your rack kit specifies a torque setting, use a torque wrench to tighten them appropriately. Follow the tightening sequence recommended by the manufacturer, often tightening fasteners in a criss-cross pattern.
Repeat for All Brackets: Continue this process for all mounting points required for your roof rack system.
Clean Up Excess Sealant: While the sealant is still wet, carefully remove any excess that squeezes out around the brackets with a lint-free cloth.

Installation Process (Drilling into Roof Skin – Use with Caution)

If your Sprinter doesn’t have factory mounting points or your rack system requires drilling, proceed with extra care. The integrity of your roof seal is paramount.

Mark Drilling Locations: Using your measuring tape, level, and masking tape, accurately mark the exact locations where you need to drill holes. Use the roof rack’s template or measurements provided in the instructions. Ensure the tape extends slightly beyond the drilling point to help catch any stray marks.
Drill Pilot Holes: Select a drill bit that is slightly smaller than the desired final hole size. Drill a pilot hole at each marked location. Start slowly and let the drill do the work.
Enlarge Holes (if necessary): If the instructions require larger holes for fasteners or mounting feet, carefully enlarge the pilot holes using the specified drill bit size or a step bit.
Deburr and Clean Holes: Remove any sharp metal burrs around the drilled holes using a deburring tool or a countersink bit by hand. Clean out all metal shavings from the holes and the surrounding roof surface.
Apply Primer (Optional but Recommended): If you have bare metal holes, apply a thin layer of metal primer to prevent corrosion. Allow it to dry according to the primer’s instructions.
Apply Sealant: Place a generous amount of automotive-grade sealant around the inside of each hole and/or over the designated mounting area on the roof. Then, apply sealant to the bottom of the mounting feet or brackets that will contact the roof.
Position and Secure Mounts: Carefully place the mounting feet or brackets over the holes, ensuring they align correctly. Insert the provided bolts through the mounts and into the holes.
Tighten Fasteners: Secure the mounts by tightening the bolts. If specified, use a torque wrench to tighten to the manufacturer’s recommended torque settings, following any specific tightening patterns.
Seal Around Fasteners: Ensure sealant completely surrounds each fastener and fills any gaps between the mount and the roof. Clean up any excess sealant.
Continue with Rack Assembly: Once all mounting points are secured, follow the remaining instructions to assemble the crossbars or platform onto the installed mounts.

Final Checks and Sealing

Once the main framework of the roof rack is attached to your Sprinter’s roof:

Attach Crossbars or Platform: Install any crossbars, platform sections, or side rails according to your specific rack’s instructions.
Tighten All Hardware: Ensure all bolts, nuts, and screws are tightened to the manufacturer’s recommended torque specifications. Overtightening can damage components or the van, while undertightening can lead to a loose rack and potential safety hazards.
Inspect for Gaps: Look carefully around all mounting points. If you see any small gaps where water could potentially enter, apply a bit more sealant.
Test Stability: Gently push and pull on the rack to check for any movement or looseness. It should feel solid and securely attached to the van.
Clean Up: Remove all excess sealant, tape, and debris from your Sprinter and its roof.
Allow Sealant to Cure: Refer to your sealant manufacturer’s instructions for proper curing times. Avoid washing the van or exposing it to heavy rain for at least 24-48 hours after installation.
