The Freightliner XC chassis is a solid foundation for diesel motorhomes, but like most stock setups, it can be improved. If your RV feels rough over bumps, sways too much in turns, or has too much steering play, a few key upgrades will make a big difference.

Shocks – First Step to a Smoother Ride

Freightliner XC motorhomes can be heavy, and factory shocks aren’t always up to the task. Upgrading to heavy-duty shocks improves ride quality and stability.

• Bilstein B6 5100: Great for controlling bounce and keeping the ride stable.
• Koni FSD: Adjusts automatically to road conditions, providing a smoother ride.

Rear Track Bars – Stops Side-to-Side Movement

Excessive movement in the rear axle can make steering feel loose and unpredictable. A rear track bar helps keep everything centered.

• SuperSteer Rear Trac Bar: One of the best solutions for improving stability.

Sway Bars – Reduce Body Roll

A stiffer sway bar improves handling in curves and crosswinds.

• Roadmaster Anti-Sway Bars: Reduces lean and makes the RV feel more planted.
• SuperSteer Sway Bar Kit: Great for extra stability, especially on long drives.

Steering Stabilizers – Keep the RV Tracking Straight

Steering stabilizers reduce driver fatigue and make highway driving easier.

• Safe T Plus Steering Stabilizer: Helps with tracking and absorbing road impacts.

Final Thoughts

The Freightliner XC chassis is already a good platform, but upgrading shocks, sway bars, and adding a rear track bar will transform the way your RV drives. These upgrades improve ride comfort, handling, and overall safety.
