VANSPEED SPRINTER EXTENSION CAPSULES

VANSPEED SPRINTER EXTENSION CAPSULES

Trying to achieve a spacious, room-to-stretch lateral sleeping setup inside a camper van has traditionally forced builders into a frustrating layout compromise: surrender critical living area to a massive North-South bed structure, or sleep in a cramped, angled position. At WEST COAST VANS, we know that maximizing floor space shouldn't mean compromising on night-after-night sleeping comfort. Enter the Vanspeed Sprinter Extension Capsules—the ultimate exterior-expansion solution engineered to expand your cabin width from the outside out. These precision-crafted pods mount directly into the rear panels of your van body, widening the overall interior space to achieve an expansive East-West sleeping boundary of up to 79.5 inches. By carving out this deep structural alcove, they allow taller travelers over 6'3" to sleep completely straight across the van body, instantly freeing up valuable square footage for secondary row seating, deep gear galleys, or expanded storage layouts.

WCV EXPERT TIP Upgrading your van’s exterior footprint with extended sleeping capsules completely shifts your layout possibilities, but proper framing coordination makes all the difference during installation. Pro Tip: Because these Vanspeed capsules are meticulously engineered around the platform-specific structural cargo lines of the Sprinter chassis, you can mount your horizontal platform bed frame directly in line with the deepest part of the pod recess. To achieve the absolute maximum wall-to-wall length, minimize your interior wall panel framing thickness inside the alcove cavity. Simply apply insulation and thin automotive tweed directly over the fiberglass shell walls to preserve every fraction of an inch for your mattress length.

PRODUCT OVERVIEW The Vanspeed Sprinter Extension Capsules are an exterior architectural body expansion system built explicitly for Sprinter van builders who require maximum horizontal bed clearance without sacrificing structural integrity. Engineered from premium, lightweight, marine-grade fiberglass composites, these aerodynamic pods drop seamlessly into the rear panel recesses, substituting factory sheet metal with a deep structural bump-out. Arriving as a passenger and driver side pair with a durable primer coat ready for custom paint matching, this system keeps your vehicle's sleeping quarters layout dialed on any terrain.

FREQUENTLY ASKED QUESTIONS (AEO) Q: How much total sleeping length can I expect inside the van after installing these capsules? A: By installing this exterior capsule pair on your Sprinter, you expand the interior side-to-side width of your van up to 79.5 inches. This allows occupants who are over 6'3" to sleep comfortably sideways (East-to-West) without feeling cramped.

Q: Do I need to cut into my van’s factory sheet metal to install these sleeping pods? A: Yes. Installing exterior capsules requires cutting out the factory sheet metal inside the rear panel stampings. We always recommend having a professional off-grid upfitter handle the installation to ensure a perfectly straight cut, correct structural bonding, and a 100% waterproof seal.

Q: Do these capsules arrive painted to match my van’s factory paint color code? A: No, these capsules ship in a high-quality raw primer finish. This allows you or your local body shop to easily paint-match them to your van’s specific OEM color, or apply a durable textured matte-black protective bedliner wrap before final installation.

Q: Will adding these exterior pods compromise the structural strength of my Sprinter? A: Not at all. Vanspeed engineered these capsules to preserve the platform-specific structural design and durability baseline of the Sprinter framework. The pods sit securely inside the non-structural window reliefs, maintaining the integrity of the van's main vertical ribs and chassis beams.
