Mercedes Sprinter Parts & Accessories
Mercedes Sprinter Van Conversion Parts
The Sprinter is the most-converted van in North America, and it is also the one where "universal fit" costs you the most time. Every part in this collection is confirmed against a specific Sprinter generation and wheelbase — NCV3 (2007–2018, chassis 906) or VS30 (2019+, chassis 907), in 144", 170", 170" EXT and dually configurations. That covers the whole build: the NVC Wall Framing Kit that turns a bare shell into a framed, insulated, wire-chased structure; pre-cut 3M Thinsulate; CNC-cut 2tec2 and Lonseal flooring; GoCode's ABS trim kits, B-pillars, window trim rings and Innie Pocket Sleepers; MobiFrame swivels for both 906 and 907; Unaka roof racks and ladders for 144 and 170; Webasto and Espar heater kits with Sprinter-specific fuel tank taps; NW Conversions wheel-well and undercarriage water tanks; and TERRA X dash mounts for the VS30 cockpit. We build Sprinters in Roanoke, so the fitment notes below come from vans on our lift.
How to Choose Sprinter Parts
1. Know your chassis code, not just your model year
This is the first question we ask on the phone. NCV3 / 906 is 2007–2018. VS30 / 907 is 2019 and newer. They differ in seat base geometry, dash architecture, roof rail design, B-pillar shape and fuel port location. Parts that care:
- Swivel seats — 906 driver/passenger and 907 driver/passenger are four different part numbers
- Dash mounts — NAVIDOK Overlander and Overlander X are 2019+ VS30 only; VISORDOK TubeTrak comes in VS30 and NCV3 versions
- Trim kits — GoCode kits are for 2014+ Cargo and Crew High Roof vans
- Ladders and racks — roof rail differences drive bracket choice
Flooring and insulation kits span 2007+ because they're cut to the cargo box, which changed less.
2. Frame it right, and everything downstream gets easier
The NVC Wall Framing Kit ($3,480 for 144, $3,780 for 170, 2019–current) is our own product and the thing we'd tell anyone building a Sprinter from bare metal to look at first. What it changes:
- Wood, not steel. The framing is a continuous thermal break rather than a heat highway. Metal furring bolts cold straight through to your wall panels; this doesn't.
- Seven fasteners into the van, total. In a full install, only seven fasteners touch the van, threading into interior structural roof ribs near the slider and headliner. None penetrate the body — the exterior sheet metal and weatherproof outer skin stay untouched. Every hole you don't drill is a rust site that doesn't exist.
- Wire chases built in. Every vertical pillar and ceiling rib includes a wire-routing chase with pre-drilled zip-tie holes, so wiring never rubs on cut steel edges — the failure that shows up 30,000 miles later as an intermittent short.
- Known geometry. Roughly 68.5" interior framed width at the floor, with the van's curves simplified to flat, known angles. Cabinet building gets dramatically simpler. Ceiling and upper wall L-track centerlines are each 12.5" from the interior finished wall panel corner, which makes prefab cabinets land where you expect.
- Two roof appliance boxes included for a 14" x 14" fan or A/C cutout, with scribed cut lines on the ceiling ribs.
Assembly is about 10 hours. Add the L Track Inserts ($40) if you want gear track — 162 inserts for a 144, 222 for a 170, 246 for a 170 EXT, sized for L-track at 4" or greater hole spacing, mounted with 1/4"-20 bolts.
3. Buy the interior trim as a kit, not as pieces
The GoCode Full Interior Trim Kit ($969–$1,819) is a 7-piece ABS set covering B-pillars, over-slider threshold, C-pillar, and rear door threshold, installing in under an hour. Finish options: RAW 3/16" haircell ABS (paint or upholster it yourself), SEM Ultra-Black matte for an OEM look, or factory-upholstered in Grey Heather or Black Marathon Tweed. Audio versions add 4" speakers or grill-ready screens. Individual pieces are available if you only need the slider threshold ($170) or the D-Pillar rear door threshold ($467.50+).
Add the Bugwall Fast Track Rail ($85) if bug screens are in your plan. It builds a slide track into the slider and rear door trim so a screen goes in in 15 minutes with no adhesive, comes out for stealth camping, and manages water at the frame. It works exclusively with GoCode Sprinter trim kits on 2014+ Cargo/Crew High Roof vans.
4. Widen the bed without cutting flares
The Sprinter 144 Innie Pocket Sleeper Pair ($492.15) is the clever one: pre-formed capsules that replace the rear quarter window trim rings and let you sleep east-west up to 77" inside the van body — no exterior flares, no extended pod. GoCode estimates over 50 hours saved versus fabricating capsules yourself. Compatible with window installs and 10x33 trim rings, and paintable or upholsterable to match the rest of the interior. The Vanspeed Capsule Trim Ring Pair ($573.75) covers the same problem for that platform.
5. Water: plan the tank around the wheel well
NW Conversions rotomolded tanks are shaped for specific van geometry, which keeps water weight low and out of your floor plan. For Sprinters: 20, 22, 24, 33 and 36 gallon wheel-well tanks in left, right and centered offsets; 19 and 25 gallon slim dually tanks; 28 gallon spare tire tank; and 11 and 22 gallon undercarriage tanks. USA-rotomolded, BPA-free food-grade plastic with flexible port options. Choose the side that balances your galley — if your kitchen is on the driver's side, put the tank on the passenger side.
6. The upgrades that make a Sprinter feel finished
- ETON Front & Center Sound Upgrade ($466.65) — a 1-for-1 plug-and-play replacement for the five factory VS30 speakers (2018+): 6.5" woofers, 25 mm tweeters in vehicle-specific mounts, 80 mm center. No cutting or rewiring; crossovers, seals and a lever tool included.
- Window trim rings — 3310 awning ($106.25), rear half-slider ($106.25), universal driver mid ($211.65), flare trim ring pair ($492.15), and 10x33 bunk window rings with storage cubbies ($169.15+).
- TERRA X cockpit — NAVIDOK Overlander/Overlander X, VISORDOK TubeTrak, CUPDOK, Charge Groove. See dash mounts.
Frequently Asked Questions
How do I tell if I have an NCV3 (906) or a VS30 (907) Sprinter? Model year is the quick answer: 2007–2018 is NCV3/906, 2019+ is VS30/907. The dash is the obvious visual tell — VS30 has the MBUX-era center screen and a different center console. If you're ordering a swivel or a dash mount, confirm the year on the door jamb sticker before you buy, because those two categories are the least forgiving.
Which Sprinter heater kit do I need, and will it fit my fuel system? Diesel Sprinters use the Espar AS3 D2L full kit ($1,525) or a Webasto diesel unit; gas Sprinters use the Espar AS3 B2L ($1,600) or the Webasto gasoline kits. Sprinters have an unused factory auxiliary fuel port, and both the Webasto 10-7-0010 tap kit and the Espar hoses are designed to use it (Espar ships a standpipe, not a T-piece; many builders add the Dorman 800-188 adapter). Important: the Webasto push-lock tank fitting does not fit 2021+ gasoline Sprinters — those tanks must be drilled for a standpipe. See heaters.
Will a swivel seat fit my Sprinter if it already has the factory swivel? No. MobiFrame Sprinter swivels are not compatible with any seat base that already has a factory Mercedes swivel installed. Keep the factory swivel and change the seat instead. Full detail in swivel seats.
What roof rack fits a 144 vs. a 170? Unaka builds rack lengths per wheelbase: Sprinter 144 High Roof (Premium $1,100; Premium Light Bar $2,100) and 170 High Roof (Premium $1,200; Premium Light Bar $2,400), plus a 170 EXT Premium Light Bar at $2,600. If you only want crossbars, the Sprinter Low Profile Crossbar Kit ($70) mounts to your OEM rail. Ladder note: the Sprinter Side Mount Ladder V2 works with OEM rails using the adapter kit ($75) — no rack required. See roof racks & ladders.
Can I use these parts on a Revel, Storyteller, Jayco Terrain or Ekko? Many, yes — these are Sprinter-platform vans. TERRA X specifically lists the NAVIDOK Overlander as compatible with Winnebago Revel, Storyteller Overland, Jayco Terrain and Tiffin, and the Charge Groove with those plus Winnebago Ekko and Leisure Travel. Revel owners must choose the "Modified Dash" option on the Overlander X — the Revel dash requires a different upper mounting bracket.
What order should I install all this in? The order we work in: strip and clean → sound deadening → framing → wiring rough-in → insulation → subfloor → finish floor → wall/ceiling panels and trim → cabinets → swivels and cockpit → roof appliances and rack. The two things people most often do out of order are swivel seats (do them before the finish floor) and roof cutouts (plan fan, A/C and solar as one layout before you drill anything).
