We're excited about our newest addition to the Mercedes-Benz Sprinter suspension lineup: the SS112 Front Auxiliary Sway Bar.

This new product represents years of research, testing, and development focused specifically on improving the handling characteristics of Mercedes-Benz Sprinter 3500 and 4500 motorhomes.

At SuperSteer and Henderson's Line Up, we are committed to understanding how a vehicle performs in the real world, not just on paper. As Sprinter-based motorhomes continued to grow in popularity, we recognized the need to better understand the unique handling characteristics of these coaches. To accomplish that, we purchased our own Sprinter motorhome and began extensive testing and development to better understand the challenges owners experience every day.

What we discovered was that while the Sprinter chassis offers outstanding fuel economy, maneuverability, and ease of driving, many owners experience excessive body roll, rocking, and stability concerns that can reduce confidence behind the wheel.

The SS112 Front Auxiliary Sway Bar was developed to address one of the most common complaints we hear from Sprinter owners: excessive body lean during cornering and maneuvering.

Why Do Sprinter Motorhomes Lean So Much?

A Sprinter starts life as a commercial van. Then manufacturers add walls, cabinets, appliances, holding tanks, furniture, cargo, and everything else that transforms it into a motorhome.

All that weight sits higher above the chassis. As a result, when the coach turns, that weight wants to keep moving. The body begins to lean, and that's what drivers feel as sway or body roll.

During our testing, we also discovered something else. The Sprinter's rear shocks are mounted relatively close to the center of the chassis. Because of this, they don't have as much leverage to control the coach body as many people might expect. That's one reason why controlling the slow speed rocking and rolling motion on a Sprinter can be more challenging than simply installing a new set of shocks.

Many owners describe the symptoms as excessive body roll in corners, rocking when entering driveways, side-to-side sway in campgrounds, instability during lane changes, driver fatigue on long trips, and reduced confidence in crosswinds.

What Does the SS112 Front Auxiliary Sway Bar Do?

Simply put, the SS112 helps control how far your coach can lean. When you enter a corner, the weight of the motorhome naturally shifts toward the outside of the turn. The sway bar resists that movement and helps keep the coach flatter and more controlled. Benefits can include reduced body roll, flatter cornering, improved steering feel, increased driver confidence, and better overall control. The SS112 being a front sway bar, it (along with the 87-2657 Font Koni Struts) will make a more immediate improvement on initial cornering response. Keep in mind that rear suspension upgrades make a difference as well and will help reduce lean and rock/roll, but during an abrupt maneuver, the sway starts with a dive up front and then settles into a lean across the whole chassis.

Why Doesn't a New Set of Shocks Solve Everything?

A sway bar controls how far the coach leans. A shock controls how fast the coach moves.

A stiffer sway bar without proper damping can actually cause the coach to want to return toward center more aggressively because sway bars act like springs. They store energy and then release it. That's where quality shocks and struts become critical.

How Do Shocks and Struts Fit Into the Picture?

At SuperSteer, we offer the SS88-1889 Rear Shocks, custom-valved by Koni to our specifications. Up front, many owners pair their suspension upgrades with Koni adjustable front struts, which help improve front suspension control and damping. These components do not replace the job of a sway bar. They complement it.

Why We Developed the SS112

As we continued testing Sprinter motorhomes, we found that upgrades like the SS110 Rear Heat-Treated Sway Bar, SS88-198 Rear Shocks, Koni front struts, and our SS701 rear trac bar substantially improve handling.

But we also discovered there was still an opportunity to improve front body roll control. That's what led to the development of the SS112.

The Difference Between the SS112 and SS110

The SS112 is mounted at the front of the coach and is designed to improve front body roll control. The SS110 is mounted at the rear of the coach and is designed to improve rear roll control. Both sway bars help reduce body roll, but they work on different ends of the vehicle and address different aspects of handling.

Why Many Owners Choose a Complete Suspension Package

There is rarely one single part that fixes everything.

The SS112 helps control front body roll.
The SS110 helps control rear body roll.
The SS88-1889 Rear Shocks help control rebound and rocking.
Koni front struts improve front suspension damping.
Rear trac bars help control side-to-side axle movement.

When combined properly, the result is a coach that feels more planted, more predictable, and more enjoyable to drive.

Frequently Asked Questions:

Q: Is the SS112 a front or rear sway bar?

A: The SS112 is a FRONT auxiliary sway bar.

Q: Does the SS112 replace the SS110 rear sway bar?

A: No. It does, however, provide additional assistance to help control sway.

Q: Will the SS112 eliminate all sway?

A: No single suspension component can eliminate every handling issue.

Q: Do I still need good shocks if I install the SS112?

A: Absolutely. A good set of shocks works synergistically with a sway bar.
