If you are shopping Thor Motor Coach suspension upgrades, here is the honest truth. Thor builds a lot of different RVs on a lot of different chassis. The right suspension parts depend on the chassis under your coach, not just the Thor name on the front cap.

Here are a few common Thor chassis setups so you can get pointed in the right direction:

• Class A gas like Hurricane rides on the Ford F53 chassis
• Smaller Class A gas like Vegas rides on the Ford E-Series chassis
• Class C like Chateau and Quantum are built on the Ford E-Series, with some ESpec models offering a Chevrolet chassis option
• Class B+ like Gemini AWD is built on the Ford Transit chassis
• Sprinter Class C like Tiburon is built on the Mercedes-Benz Sprinter chassis
• Super C like Magnitude Grand rides on Ford F-550 or F-600 chassis depending on the model
• Diesel pusher like Palazzo GT is built on a Freightliner XC-S chassis

Once you know your chassis, the upgrade path gets a lot easier. If the coach keeps rocking after bumps or feels like it floats, start with proper RV shocks. If it leans hard in turns or gets pushed around by wind and passing trucks, you are usually looking at sway control. If it wanders and you are making constant steering corrections, steering control and axle control parts can make a big difference.

Shop the parts above to tighten up handling and make your Thor easier to drive. If you are not sure what chassis you have, contact us before ordering with your year, model, and any chassis info you can find. We will help you match the right parts the first time.
