SuperSteer® Rear Trac Bar for 1992-2020 Ford E350 & E450 Class C Motorhome Without Factory Rear Sway Bar (Part Number SS402)

Eliminate “Tail Wagging the Dog” and Improve Rear Stability on Your Ford Chassis

If you’ve ever felt the rear of your coach shift when correcting the steering wheel, you’ve experienced the dreaded “Tail Wagging the Dog.” That sudden side-to-side movement of the rear axle forces constant steering correction and makes driving stressful — especially in crosswinds or when being passed by large trucks.

The SuperSteer® SS402 Rear Trac Bar is engineered specifically for the Ford E350 and E450 Class C Motorhome to eliminate uncontrolled rear axle side shift. By stabilizing the rear suspension, it dramatically improves tracking, steering response, and overall driver confidence.

With the rear axle firmly controlled, your motorhome tracks straighter, responds more predictably, and requires fewer steering corrections. The result is a safer, more relaxed driving experience for you and your passengers.

If you’re looking to improve stability, reduce driver fatigue, and gain better control of your motorhome, the SS402 Rear Trac Bar is one of the most effective suspension upgrades you can make.
