Mercedes Sprinter Wide Body Kit: Fender Flares and Arch Extensions

Information: Mercedes Sprinter Wide Body Kit: Fender Flares and Arch Extensions

A mercedes sprinter wide body kit adds fender flares and wheel arch extensions that widen the visual stance of your VS30 or W907 Sprinter by up to 40 mm per side, allowing fitment of wider wheels and giving the van a muscular, purpose-built appearance. At DL Auto Design we manufacture these parts in-house in Lithuania from ABS plastic and fiberglass, supply them paint-ready or finished, and ship worldwide with EU 0% VAT for non-EU buyers including the United States.

Why US Sprinter Owners Are Choosing Wide Body Arch Kits in 2025

The Mercedes Sprinter VS30 - sold in the US as the 2500, 3500 and 3500XD - is increasingly used for luxury shuttle, camper van and high-end cargo builds. Owners want a wider, more aggressive stance that separates their van from a standard fleet unit. Sprinter fender flares are the single most visible change you can make to the exterior without cutting metal.

Wide fender flares also serve a practical purpose. If you have fitted wider aftermarket wheels or leveling spacers, factory arches often do not provide enough coverage to meet US state tire-coverage rules. Arch extensions bring the body line out to cover the tread legally and cleanly.

Demand for wheel arch kits has grown alongside the camper-van and van-life movement. A widebody stance signals a premium, custom build and raises resale value on conversion vans in the US market.

Generation and Wheelbase Fitment: Getting It Right Before You Order

Fitment is the most critical factor when buying a sprinter fender flares kit. The wrong generation or wheelbase produces gaps, mis-drilled mounting holes and panel gaps that are expensive to fix.

We at DL Auto Design produce arch flares specifically keyed to the W907 body shell. Our Mercedes Sprinter W907 Arch Flares are engineered to the exact OEM body contour of the 2019-2025 platform so no gap-filling or custom fabrication is needed on installation day.

Wheelbase length - L1 through L4 - affects the rear quarter panel geometry. Always confirm your wheelbase code with your VIN or door-jamb sticker before placing an order. Our product pages list compatible wheelbase codes for each part.

Materials: ABS Plastic vs Fiberglass for Fender Flares

The material you choose affects weight, flexibility, paint adhesion and long-term durability. We offer both options so you can match the choice to your build goals.

• ABS plastic: Impact-resistant, slightly flexible at low temperatures, bonds well with factory paint primers. Recommended for daily-use vans, rental fleets and builds that may encounter minor parking impacts.
• Fiberglass / FRP: Lighter than ABS on large panels, easier to sand and shape for custom paint prep. Preferred for show builds, luxury camper conversions and cases where weight saving matters.

Both materials ship paint-ready with a smooth primer-compatible surface. We also offer pre-painted parts if you supply your Mercedes paint code, saving you bodyshop time and cost.

What a Complete Sprinter Wide Body Kit Includes

A true wide body kit is more than fender flares alone. To achieve a coherent, factory-quality look across the whole van, the arch extensions need to read as part of a unified exterior design.

1. Front arch flares - extend the front wheel opening to match wider front tires or spacers
2. Rear arch flares - cover the extended rear track, critical for rear dual-wheel 3500 XD builds
3. Side skirts - bridge the visual gap between front and rear arches, keeping the body line continuous
4. Matching front bumper - a sport or tuning bumper that shares the same design language as the arch kit

For buyers who want a complete exterior transformation, our Mercedes Sprinter W907 W910 Full Body Kit with Front Grille Diamond bundles front, side and rear elements into one matched package, eliminating the risk of mismatched panel profiles.

Parking Sensors, Cameras and ADAS: What to Know

The 2019-2025 VS30 / W907 Sprinter may be equipped with front and rear parking sensors, a reversing camera, lane-keep assist and active brake assist. Any arch extension or bumper work that affects the front or rear fascia must account for sensor housings and radar sight lines.

We design our arch flares not to interfere with side radar or ultrasonic sensors. However, if your van has factory side-mounted parking sensors in the wheel arches, confirm with our team before ordering. We can advise on cutout requirements at no extra charge.

Rear arch flares on dual-rear-wheel 3500 models sometimes cover the inner rear-facing sensors. We include mounting notes with each kit and recommend verifying sensor function in a parking-lot test before final bodyshop paint.

Installation Overview and Paint Preparation

Wide fender flares on a Sprinter are typically a one-day bodyshop job when the parts arrive paint-ready and correctly fitted to your generation. Below is the standard process we recommend to US installers.

• Clean and degrease the arch area with panel wipe
• Dry-fit the flare, mark mounting points, drill pilot holes
• Apply 3M VHB automotive tape to the bonding surface for a weather-tight bond
• Secure with stainless M6 bolts through pre-drilled flanges where applicable
• Skim-fill any small gaps with flexible polyurethane body filler
• Sand to 400 grit, apply filler primer, top coat to match vehicle color code

Parts ordered pre-painted from us arrive color-matched to your Mercedes paint code and need only a light clear-coat blend at the edges. This cuts shop time by approximately half compared to raw parts.

Shipping to the US, Duties and VAT

We ship all parts from Lithuania to US addresses via DHL Express, FedEx or freight forwarder depending on kit size. Typical transit time to US ports is 5 to 9 business days for express shipments.

US customers are non-EU buyers and therefore pay 0% EU VAT on every order placed through our website. You pay only the product price plus shipping. US import duties (HTS codes for automotive body parts, typically 2.5% for plastics) are the buyer's responsibility at the border, but our team provides accurate commercial invoices and HS codes to simplify customs clearance.

Full body kits ship in flat-pack crates dimensioned to minimize freight class costs. We provide tracking from despatch to delivery and can consolidate multi-part orders into a single shipment.

TUV Certificates and Road Legality

Many of our structural exterior parts carry TUV material or design certificates issued in the EU. Arch flares and fender extensions are cosmetic bolt-on parts and do not require TUV homologation in most US states, but they must not reduce tire coverage below the tread width. Always check your state DMV guidelines on fender coverage before fitting wider wheels.

For European customers importing a US-specification W907, our TUV-certified parts help satisfy periodic technical inspection requirements. Certificate documentation is supplied with qualifying products.

Choosing the Right Finish: Gloss Black, Body Color or Matte

Wide fender flares look intentional in three finishes. The right choice depends on your build theme.

• Body color match: Seamless, OEM-plus look. Best for luxury shuttle and conversion builds where buyers want a factory-custom appearance.
• Gloss black: Contrasting sport look. Popular on white and silver Sprinters in the US market. Fast, low-cost finish option.
• Matte or satin: Textured finish that hides minor surface imperfections. Popular for overlander and expedition builds.

Frequently Asked Questions

Will these fender flares fit my 2022 Mercedes Sprinter 3500?

Yes. The 2022 Sprinter 3500 is a W907 / VS30 platform. Our W907 arch flares are designed for the 2019 to 2025 model years. Confirm your wheelbase code (L1, L2, L3 or L4) when ordering so we supply the correct rear quarter geometry.

Do I need to cut the factory fenders to install wide fender flares?

No cutting of metal is required for our bolt-on arch extension kits. They mount over the existing factory arch using adhesive tape and bolts through pre-drilled flanges. A bodyshop can complete the installation in one day.

How much wider do the arch flares make the Sprinter?

Our W907 arch flares extend each wheel arch by approximately 30 to 40 mm per side. This allows fitment of wheels up to 40 mm wider per axle without the tire extending past the body line.

Are ABS or fiberglass arch flares better for a camper van build?

For a camper van that sees daily road use, ABS is more forgiving of minor impacts and temperature changes. Fiberglass saves weight and is easier to achieve a show-quality paint finish on, so it suits high-end conversion builds where weight reduction matters.

Do US buyers pay EU VAT on orders from DL Auto Design?

No. Buyers outside the EU, including all US customers, pay 0% EU VAT on every order. You pay only the listed product price plus shipping. US import duties are assessed at the border and are the buyer's responsibility.

Can I order the arch flares pre-painted to my Sprinter color?

Yes. Supply your Mercedes paint code when ordering and we will apply a matched factory color before shipping. Pre-painted parts need only a light clear-coat blend at the edges, significantly reducing installation time at the bodyshop.

A mercedes sprinter wide body kit with fender flares is the most impactful single exterior upgrade available for the VS30 / W907 platform in 2025, combining a stronger visual stance with practical wheel and tire coverage.
