Hellwig 7182 1-1/2" Rear Sway Bar Kit 1999-2022 Ford E-350 DRW Cutaway Chassis

Vehicle Fitment

• 1999-2022 Ford E-350 Super Duty - Dual Rear Wheel (DRW) Cutaway Chassis, 2WD - with rear disc brakes and factory rear sway bar only

Fitment Notes

• CUTAWAY CHASSIS ONLY - the 7182 is engineered specifically for the Ford E-350 Super Duty Dual Rear Wheel (DRW) Cutaway Chassis configuration. It does NOT fit the standard E-350 cargo van, passenger van, or Club Wagon body-on-frame configurations. Verify that your vehicle is the cutaway chassis variant before ordering.
• REAR DISC BRAKES REQUIRED - this sway bar fits E-350 DRW Cutaway Chassis vehicles equipped with rear disc brakes only. The 7182 does NOT fit vehicles with rear drum brakes. Verify your E-350's rear brake configuration before ordering.
• FACTORY REAR SWAY BAR REQUIRED - the 7182 is designed to replace the factory-installed rear sway bar using the factory axle saddle mounting points. The vehicle must be equipped with a factory rear sway bar for this installation to proceed as a direct replacement. Per the installation instructions, if no factory sway bar is present, axle U-bolts may be used - but this product is specified for factory sway bar applications only.
• The Ford E-350 DRW Cutaway Chassis is commonly used as the base for Class C motorhomes, shuttle buses, ambulances, box trucks, airport/hotel vans, and small school buses. This sway bar is widely used in all of these applications.
• This bar is distinct from the Hellwig 7180, which fits the Ford E-450 platform. The E-350 DRW Cutaway and E-450 are separate chassis platforms with different rear axle geometry and sway bar mounting configurations - the 7182 and 7180 are not interchangeable.
• All mounting hardware, polyurethane bushings, end links, and brackets are included - no additional hardware purchases are required.

Features

• 1-1/2" (38mm) solid bar diameter - significantly larger and stiffer than the factory rear sway bar, providing substantially more torsional resistance to body roll, lateral sway, and crosswind deflection on the E-350 DRW Cutaway Chassis platform.
• Solid construction from heat-treated chromoly steel (ASTM 4140) - delivers a tensile strength of 170,000 psi and superior fatigue resistance compared to conventional mild steel factory sway bars, engineered to withstand the demanding torsional stress cycles of high-profile, heavy-duty chassis operation over the full service life of the vehicle.
• High-durometer polyurethane bushings at all mounting points - more compression-resistant and durable than factory rubber bushings, maintaining precise bar positioning under sustained load and eliminating the deflection and bushing decay that degrade factory sway bar performance over time.
• Forged integral end-link landings - maximum strength at the bar's attachment points with no welded or press-fit brackets that can fatigue and fail under repeated torsional stress.
• Reduces side-to-side body roll in corners and during lane changes - particularly critical for high-profile E-350 DRW Cutaway applications (motorhomes, shuttle buses, box trucks) where a tall body, high center of gravity, and large frontal area create significant lean and sway under cornering and crosswind loading.
• Dramatically improves crosswind stability on the highway - reduces the lateral displacement and body lean caused by passing truck wake, bridge gusts, and high-speed lane changes that are amplified by the E-350 DRW's tall, boxy body configurations.
• Improves overall handling balance by reducing rear body roll, resulting in more neutral steering response and better tire grip distribution across all four wheels during cornering.
• Designed to replace the factory rear sway bar using factory axle saddle mounting points - bolt-on installation with the vehicle's weight on the suspension (do not raise by frame during installation). No drilling required.
• Maintains everyday ride comfort during straight-line driving - sway bars do not affect spring rate, so the 7182 will not create a stiffer or harsher ride on normal highway travel.
• Hammertone powder coat finish for corrosion resistance in the harsh underbody environment encountered in year-round commercial operation of E-350 DRW Cutaway vehicles.
• Manufactured at Hellwig's ISO 9001 and ISO 14001 certified facility in Visalia, California - made in the USA since 1946, backed by Hellwig's Limited Lifetime Warranty against manufacturing defects.

Product Description

The Hellwig 7182 is a 1-1/2" solid chromoly rear sway bar kit engineered specifically for the 1999-2022 Ford E-350 Super Duty Dual Rear Wheel (DRW) Cutaway Chassis - the foundation for a wide range of Class C motorhomes, shuttle buses, ambulances, box trucks, and specialty commercial vehicles. Three critical fitment requirements must be met for the 7182 to install correctly: the vehicle must be the DRW Cutaway Chassis configuration (not a standard E-350 van), it must be equipped with rear disc brakes, and it must have a factory-installed rear sway bar that the 7182 will replace. Buyers who meet all three criteria will find the 7182 to be one of the most impactful single suspension upgrades available for the E-350 DRW Cutaway platform - replacing the undersized factory bar with a larger, stiffer chromoly unit that delivers a dramatically more stable, controlled ride under the high-profile body configurations these chassis typically support.

The 7182 is manufactured from heat-treated ASTM 4140 chromoly steel with a 1-1/2" solid cross-section and a tensile strength of 170,000 psi, providing substantially more torsional stiffness than the factory bar. Hellwig uses high-durometer polyurethane bushings throughout - at the center axle mounts and end link attachment points - rather than the rubber bushings used at the factory, maintaining precise bar positioning under sustained load and eliminating the gradual degradation in handling performance that occurs as factory rubber bushings compress, crack, and deteriorate over years of commercial service. All mounting hardware, end links, saddle brackets, and installation instructions are included; no additional purchases are required.

Installation uses the factory axle saddle mounting points and frame end link attachment locations - a direct bolt-on procedure requiring no drilling or permanent chassis modifications. The installation instructions specify that the vehicle weight must remain on the suspension throughout installation (do not raise by frame), allowing the bar to be properly aligned before final torque is applied. The 7182 complements a front sway bar upgrade and upgraded shock absorbers for a comprehensive handling improvement package on the E-350 DRW Cutaway. Note that this bar is a separate and distinct product from the Hellwig 7180, which is engineered for the Ford E-450 platform - the two are not interchangeable. Manufactured at Hellwig's ISO 9001 and ISO 14001 certified facility in Visalia, California and backed by a Limited Lifetime Warranty.
