Sprinter Fender Flares: ABS, PP and Rubber Arch Options

Information: Sprinter Fender Flares: ABS, PP and Rubber Arch Options

Sprinter fender flares are bolt-on or adhesive-mounted arch extensions that widen the wheel arch opening, cover wider tyres, and give the Mercedes Sprinter (VS30 / W907 / W906) a muscular stance without a full body conversion. At DL Auto Design we manufacture arch flares and wide-body kits from ABS plastic and fibreglass/FRP, engineered specifically for each Sprinter generation and wheelbase so every panel fits flush on the first attempt.

Why Add Fender Flares to a Mercedes Sprinter?

A stock Sprinter sits on relatively narrow arches designed around a utilitarian brief. Fender flares solve three real problems at once: they accommodate wider aftermarket wheels or dual-fitment tyres that creep past the OEM arch lip, they prevent gravel and road debris from being flung at following traffic, and they dramatically reshape the van's silhouette from fleet-plain to purpose-built custom.

For US buyers running a VS30 Sprinter 2500, 3500, or 3500XD, wider arches are a common first step before adding a lift kit or switching to all-terrain rubber. In Europe the same demand comes from conversion builders who want a wide-body aesthetic on a W907 or W910 VIP transport. Regardless of end use, the material and mounting method you choose will define how long the flares last and how clean the result looks.

Material Comparison: ABS, PP, Fibreglass and Rubber

ABS is the most popular choice for Sprinter owners who want a factory-quality colour match. The surface accepts automotive primer and topcoat without the adhesion problems that raw PP can present. Fibreglass delivers the sharpest body lines and is preferred for show-quality builds where every contour must be perfect, but it requires more careful handling during install to avoid cracking at the mounting points.

Rubber arch trims are the simplest solution - they clip or self-adhere over the existing arch edge and require no painting. They are widely used on commercial vans where function outweighs aesthetics, but they rarely achieve the integrated look that ABS or FRP flares provide.

Sprinter Generation Fitment Guide (W906, W907, W910)

Fitment is the single most critical variable when buying Sprinter fender flares. The three active Sprinter platforms share almost no body panels, and arch geometry changes again between wheelbases within each generation.

• W906 (NCV3, 2006-2018 / US model years 2007-2018): This generation uses a more rounded arch profile. Flares must clear the wider front track on High Roof variants and avoid the lower body crease line that runs behind the front wheel.
• W907 / VS30 (2018-present / US model years 2019-2026): The current generation has a sharper, more angular arch lip. Rear arch flares must also respect the lower body character line and the step-in panel above the rear wheel. This is the most requested fitment at DL Auto Design in 2025.
• W910 (4x4 and special-body variants): Shares the W907 front architecture but may have altered rear quarter geometry depending on the conversion. Confirm your exact chassis code before ordering.

Wheelbase matters equally. An L1 short-base van and an L4 extra-long van use the same arch cut-out width but the surrounding body panels differ, which can affect how a rear flare sits against the surrounding sheet metal. We always ask customers to confirm their wheelbase alongside the generation code.

Wide Arch Options for the Sprinter 4.5 and Extended Wheelbase Builds

The term Sprinter 4.5 refers to a US-market cab-chassis configuration (the 4500 series) that shares the VS30 / W907 platform. Wide arch flares for this variant must clear the rear dual-wheel setup on certain trims, so the rear flare profile is wider and set further back than on a standard cargo variant.

For extended wheelbase (L3 and L4) builds the rear flares also need to clear a longer flat rear quarter panel. We design our Mercedes Sprinter W907 Arch Flares to fit both standard and extended rear sections, with the mounting hardware adjusted accordingly so there are no unsightly gaps at the trailing edge of the flare.

Wide-body builds that add 30-50 mm of visual width per side typically combine arch flares with matching side skirts to maintain proportion. If you are building a complete exterior package, our Mercedes Sprinter W907 and W910 Full Body Kit bundles arch flares with front and rear bumpers and a grille so every panel is designed as a set.

ABS vs Fibreglass: Which Should You Choose?

Choose ABS if you want the part delivered paint-ready, plan to have the flares colour-matched at a body shop, and need a part that will survive minor car-park impacts without cracking. ABS is also marginally lighter than equivalent FRP sections, which matters on a van that is already close to its payload limit.

Choose fibreglass / FRP if you are building a show van or a VIP transfer vehicle where surface definition and panel-gap precision are the priority. FRP holds sharper edges and can be worked with filler and sandpaper more easily than ABS for a glass-smooth finish. The trade-off is brittleness at thin sections - fibreglass flares need careful mounting to avoid stress cracks around the fixing points.

Installation: Mounting Methods and ADAS Considerations

Most Sprinter arch flares use a combination of stainless self-tapping screws into the existing arch lip and automotive-grade double-sided tape along the flat contact surface. Some wide-body kits add a fibreglass backing plate bonded behind the arch to create a solid fixing surface without drilling the painted body.

On W907 and W910 Sprinters built after 2021 the front corners may house active parking sensors and, on some export markets, a blind-spot monitoring radar unit. Before drilling any fixing point in the front arch area, locate all sensor positions using the vehicle's electronic map or a sensor tester. Our ABS flares include pre-cut sensor apertures for the most common sensor layouts to prevent signal interference.

Surface preparation is non-negotiable. Clean the arch lip and surrounding paint with isopropyl alcohol, allow it to dry fully, and apply the 3M or Tesa tape only to a surface above 15 degrees Celsius. In cold climates the tape bond can fail within weeks if applied to a cold panel. Prime bare ABS edges before painting to prevent peeling at the flare border.

Paint Options: Body Colour, Matt Black and Two-Tone

Sprinter fender flares leave our facility in one of three states: unpainted (bare ABS or FRP, sanded and primed ready for your body shop), factory-matched to a specific Mercedes colour code, or finished in satin / gloss black as a contrasting trim element.

Body-colour matching is the most popular choice for executive and VIP builds where the van needs to look like a factory product. Satin black is preferred on commercial ambulance conversions and off-road builds because it hides minor scuffs and does not require polishing. Two-tone - body colour on the upper body, black on the arch flare - is a current trend in the US market in 2025 for cargo vans used by creative agencies and tech companies.

Shipping to the US, Customs and VAT

We ship worldwide from Lithuania by air freight or ocean consolidation. US customers importing Sprinter body parts pay no EU VAT because we zero-rate all exports to non-EU destinations. US Customs classifies exterior plastic automotive parts under HTS Chapter 87, and import duty rates for ABS plastic parts are typically in the 2.5-3.5 percent range, though we recommend buyers verify the current rate with their customs broker before ordering.

Air freight to the US East Coast or West Coast takes 5-7 business days for standard shipments. Large fibreglass panels ship as oversized freight and may require 10-14 days. We provide full commercial invoice documentation, HS codes, and country-of-origin certificates with every shipment to simplify customs clearance.

TUV Certification and Road Legality

Several DL Auto Design body parts carry TUV certificates, which confirm that the component has been independently tested to European safety standards. For fender flares specifically, road legality in most EU countries requires that the flare fully covers the tyre tread width at all steering angles and does not add excessive projection beyond the bodywork envelope defined by national type approval rules.

In the US, arch flare legality varies by state. Most states require that the flare covers the full tyre width when viewed from directly above. There is no federal TUV requirement, but having a TUV-tested part is useful evidence if a state inspector questions the modification. Always check your state's vehicle modification statutes before installing wide-body arches on a registered commercial vehicle.

How to Order the Correct Arch Flares

1. Identify your Sprinter generation: W906 (2006-2018), W907 / VS30 (2019-present), or W910.
2. Note your wheelbase code: L1 (short), L2 (standard), L3 (long), or L4 (extra-long). US 2500 is typically L1 or L2; 3500XD is L3 or L4.
3. Confirm your body style: panel van, crew van, cab chassis (the 4500 series), or high-roof.
4. Choose your material: ABS for daily use and colour match; FRP for show quality.
5. Specify finish: unpainted / primed, painted to your Mercedes colour code, or gloss / satin black.
6. List any sensor positions you need apertures for (front parking sensors, corner radar).

Frequently Asked Questions

What are Sprinter fender flares made of?

At DL Auto Design we offer Sprinter fender flares in ABS plastic and fibreglass (FRP). ABS is flexible, paint-ready and ideal for daily use. Fibreglass is rigid and delivers sharper panel lines preferred on show builds. Rubber arch trims are also available as a simpler clip-on option for commercial vans.

Will fender flares from a W906 Sprinter fit a W907 VS30?

No. The W906 (2006-2018) and W907 / VS30 (2019-present) have completely different arch profiles and body panel geometry. Flares are generation-specific and must be ordered for your exact chassis code. Fitting a W906 flare on a W907 will leave visible gaps and incorrect curvature.

Do I need to paint Sprinter arch flares before fitting?

If you order unpainted ABS flares you should prime and paint them before installation. Applying body-colour paint after the flare is fitted makes masking difficult and risks overspray on the surrounding arch. We can supply flares pre-painted to your Mercedes colour code so they arrive ready to bolt on.

Are DL Auto Design fender flares legal on US roads?

Most US states require arch flares to fully cover the tyre tread width when viewed from above, which our flares do. However, vehicle modification laws vary by state, so we recommend checking your state's statutes before registering the modification. Several of our body parts carry TUV certificates, which can support legality discussions with inspectors.

How long does shipping to the United States take?

Air freight from Lithuania to the US East or West Coast typically takes 5-7 business days. Oversized fibreglass panels may require 10-14 days via freight consolidation. US buyers pay no EU VAT on their order. We provide all customs documentation including HS codes and country-of-origin certificates.

Can I fit Sprinter fender flares myself or do I need a body shop?

ABS flares with a clip and tape mounting system can be fitted by a competent DIY installer with basic tools in 2-4 hours per axle. Fibreglass flares that require drilling into the arch lip and use a backing plate system are better handled by a body shop that can also paint the flares at the same time. Always test sensor positions before drilling.

Sprinter fender flares are one of the highest-impact single upgrades available for a W906, W907, or VS30 van: they reshape the vehicle's stance, protect the bodywork from road debris, and open the door to wider wheel and tyre combinations. The right material - ABS for everyday use, fibreglass for show-quality builds - combined with correct generation and wheelbase fitment determines whether the result looks factory or afterthought. We at DL Auto Design design, manufacture and ship our arch flares from Lithuania to customers across the US and worldwide, with zero EU VAT for non-EU buyers and full customs documentation included.
