Weldtech Lift Kits – 4 inch Lift Vs. 6 inch lift for your Ford Econoline RV – Comparison

🚙 Weldtec 4‑Inch Lift: Balanced and Practical

✅ Advantages

• Stability & Handling: A moderate lift preserves better on-road handling, minimizing body roll and avoiding the “darty” feel noted by suspension pros sportsmobileforum.com+15thorforums.com+15youtube.com+15.

• Ground Clearance: Adds enough height to clear driveways and mild off-road terrain without over‑raising entry steps.

• Smoother Ride: Many users report a comfortable, less jarring ride—even on choppy roads—while still improving articulation sportsmobileforum.com.

⚠️ Considerations

• Entry Step Height: You’ll still add ~4″ to the step-in height; some owners say it can be a challenge for shorter users .

• Limited Tire Upgrades: Typically accommodates up to ~35″ tires without extensive trimming.

🚀 6‑Inch Lift: Maximum Clearance

✅ Advantages

• Extra Clearance: Great for serious off-road terrain or steep driveways—6″ gives a full 4″ better clearance compared to the 4″ kit.

• Aggressive Look & Larger Tires: Supports bigger wheels and gives your RV a more rugged appearance youtube.com+3sportsmobileforum.com+3youtube.com+3.

⚠️ Considerations

• Reduced Stability: The higher center of gravity can compromise stability at highway speeds; watch for increased body sway and “roll-over steer” thorforums.com.

• More Step Height: Entry becomes noticeably higher—possibly tough for kids or less mobile passengers.

• Potential for Obstructions: Some users report headlights, door clearance, or step rub issues depending on terrain thorforums.com.

• Reinforcement Needs: Might require upgraded bump stops, shock straps, and longer brake/steering lines to handle extra travel.

⚖️ Summary Comparison

🔧 Real User Feedback

“The 4″ lift … stability and ease of driving is SOOOO much better. … All of the squeaking/rattling inside the RV was gone.” sportsmobileforum.comthorforums.com+1sportsmobileforum.com+1weldtecdesigns.com

“I once caught the battery tray … on a 6″ rock, but otherwise the clearance has been fine.” thorforums.com

However, an experienced suspension engineer warns:

“The lift kit would make the Axis much less stable … risk creating … roll oversteer.” youtube.com+9thorforums.com+9youtube.com+9

🛍️ Product Options

Here are the WeldTec kits most relevant to your RV:

WeldTec Ford E‑Series Class C RV Lift Kit – Available in both 4″ and 6″ versions (“Performance” for 4″, “Off‑Grid/Baja Grocery Getter” for 6″). Includes leaf springs, shocks (Fox or King), and brackets tailored to Class C chassis. Priced around $5,600–$5,800.

✅ Which Should You Pick?

• Go 4″ if you:

  • Drive mostly highway and paved roads.

  • Want better clearance without major handling trade‑offs.

  • Care about keeping entry-step height manageable.

• Go 6″ if you:

  • Regularly tackle off‑road, steep driveways, or trails.

  • Prioritize maximum clearance and tire size.

  • Don’t mind supporting mods (longer lines, bump stops, perhaps step solutions).

⚠️ Final Considerations

1. Entry Step Solutions: For 6″, consider retractable steps or grab handles to aid boarding.

2. Suspension Extras: Add shock straps, bump-stop upgrades, and possibly swaybar tuning to preserve on-road safety.

3. Alignment & Handling: After installation, schedule a full alignment and consider sway-bar or adjustable-rate shocks if you go 6″.

Conclusion

For the Château 22E on an E‑350, most owners lean toward the 4‑inch lift—it provides a solid boost in clearance and comfort with minimal downsides. If you’re aiming for maximum off-road readiness and don’t mind a more involved setup, the 6‑inch can work—but demands careful handling of stability and convenience trade‑offs.
