Vehicle Fitment

• 2014-2018 Mercedes-Benz Sprinter 3500 (Dual Rear Wheel/Dually, 2WD & 4WD, All Engines)

Fitment Notes

• Fits Dual Rear Wheel (DRW/Dually) configurations only - does not fit Single Rear Wheel (SRW) Sprinter 3500 models.
• Does not fit Front-Wheel Drive (FWD) Sprinter 3500 models.
• Fits both 2WD and 4WD (4x4) rear-wheel drive configurations.
• This bar reuses the factory end links - end links are not included in the kit and must be retained from the original vehicle.
• This part number covers the 2014-2018 model years; earlier Sprinter 3500 applications (2008-2013) use a different Hellwig part number.
• Many RV conversions built on the Sprinter 3500 chassis use prior-year chassis; verify the actual chassis model year before ordering.

Features

• Purpose-built rear sway bar specifically engineered for the 2014-2018 Mercedes-Benz Sprinter 3500 Dually platform, including RV, camper van, and commercial hauler applications.
• 1-1/2" diameter solid 4140 chromoly steel bar - significantly larger than the factory bar - for over 20% greater roll stiffness and dramatically reduced body sway.
• Engineered to resist sway and wind drift, especially effective on high-profile van conversions, Class B+ and Class C RV builds, and cargo-loaded commercial vehicles.
• Reduces body roll by keeping weight distributed evenly across all four wheels during cornering, improving traction and safety.
• Reuses factory end links for a clean, OEM-style integration with no aftermarket link hardware required.
• OEM-style polyurethane bushings included for precise, noise-free fitment with superior roll resistance versus rubber bushings.
• Silver vein powdercoated finish for corrosion resistance and long-term durability in all operating environments.
• Heat-formed as a single piece from 4140 chromoly steel - more resistant to shape deformation than cold-bent aftermarket bars.
• Quick bolt-on installation using factory mounting locations - no cutting, drilling, or welding required.
• Made in the USA at Hellwig's ISO 9001:2015 certified Visalia, California facility. Backed by a Limited Lifetime Warranty.

Product Description

The Hellwig 7515 Rear Sway Bar is a direct-fit suspension upgrade engineered specifically for the 2014-2018 Mercedes-Benz Sprinter 3500 equipped with dual rear wheels. The Sprinter 3500's factory suspension is designed around ride comfort and load capacity for commercial use, but its factory sway bar is undersized for the demands placed on high-roof van conversions, Class B+ and Class C RV builds, slide-in campers, and loaded commercial cargo vans. The 7515's 1-1/2" solid chromoly bar delivers over 20% more roll stiffness than stock, dramatically reducing the side-to-side sway, wind sensitivity, and body lean that make these tall vehicles challenging to drive - particularly on highways or in crosswinds.

A standout feature of this kit is its use of the factory end links. Rather than requiring replacement aftermarket end links, the 7515 is engineered to retain the original Mercedes-Benz end links, simplifying installation and maintaining OEM integration. The bar itself is hot-formed as a single piece from heat-treated 4140 chromoly steel, making it more resistant to shape deformation at the bends compared to cold-bent aftermarket alternatives. OEM-style polyurethane bushings are included for precise fitment, reduced noise, and long service life. The silver vein powdercoat finish protects against corrosion in all weather conditions.

Fitment is confirmed for 2014-2018 Mercedes-Benz Sprinter 3500 models in both 2WD and 4WD configurations, but is strictly limited to Dual Rear Wheel (DRW/Dually) variants - Single Rear Wheel and Front-Wheel Drive models are not compatible. This part number is distinct from earlier Sprinter 3500 applications; owners of 2008-2013 chassis should verify their specific part number before ordering. Built at Hellwig's ISO 9001:2015 certified Visalia, California facility and covered by a Limited Lifetime Warranty, the 7515 is one of the most targeted and effective handling upgrades available for this platform.
