Why Sprinter Capsules Exist
Why Sprinter Capsules Exist
Factory Sprinter wall curvature limits sleeping width and usable interior space.
Without expansion, many van owners must:
• Sleep diagonally
• Build narrower beds
• Sacrifice layout flexibility
Sprinter Capsules extend usable width and create true horizontal sleeping space.

Description
Looking for extra room? Every inch is valuable when it comes to campervans, and now you don't have to sacrifice comfort for space.
Introducing the Vanspeed Capsules – your answer to extended sleeping space without the hassle. Crafted from durable lightweight fiberglass, these capsules add up to 10 inches of vital head-to-toe sleeping area. Their aerodynamic design and precise body fitment ensure a seamless integration with your Sprinter van. Perfect for the do-it-yourself enthusiast or the seasoned professional installer, these capsules are designed for a straightforward setup, ensuring you're ready for the road with ease and comfort.
Included with your purchase of the Sprinter Capsules are 2 gel coated driver/ capsules, SikaFlex urethane, as well as all the necessary hardware for installation.
If you prefer windows included w/ this purchase, click the Bunk Window add-on option before checkout.
We also offer the option to have your Capsules sprayed with Phoenix Coating.
Phoenix Coating helps protects against dents, scratches and off road pin striping, while staying easy to clean.
It is UV protected to prevent fading over time, and features a fine controlled texture finish that's not overly aggressive, leaving you a clean high end finish.

Sprinter Capsules FAQ's
Do capsules require cutting?
Yes. Installation requires cutting the factory body panel to integrate the expansion units into the van’s exterior wall structure. This is a structural modification that allows the capsule to extend beyond the factory curvature and create additional interior width. Professional installation is recommended unless you have experience with metal fabrication and body modification.
Are instructions included?
Yes. Detailed fitment guidance is provided to support proper alignment, sealing, and structural integration. The instructions outline cutting measurements, mounting procedures, and hardware placement to ensure a secure and weather-resistant installation.
Do they affect insulation?
Capsules integrate with standard van insulation strategies. After installation, the expansion area can be insulated and finished like the rest of the interior wall system. Proper sealing and insulation ensure thermal performance and moisture protection remain consistent throughout the build.
Will Sprinter Capsules affect the exterior appearance of my van?
Yes. Capsules extend the side body outward to increase interior width. The exterior profile will change to accommodate the expansion units, but they are designed to integrate cleanly with the van’s body lines and maintain a factory-like finish when properly installed.
Can tall people sleep sideways in a van with Capsules?
Yes. Capsules expand the interior width to 79.5 inches, allowing people 6’3” and taller to sleep east-to-west instead of lengthwise. Many users up to 6’6” can comfortably sleep sideways, depending on mattress thickness and interior trim.
