I checked with SumoSprings and they told me without the spacer the #SSR-130-54 is 5 inches tall and with the spacer is 6 inches tall.

Yes, we do have confirmed SumoSpring fits for your 2018 Thor Vegas 27.7. For your 2018 Thor Vegas built on a Ford E-450 van chassis you can use front SumoSprings #SSF-106-40 or #SSF-106-47 if the vehicle is 2-wheel drive. There is no SumoSpring…

This is a great question and one that can cause some confusion. SumoSprings capacity is determined by how much weight it takes to compress the spring down to 50% of its original body height, so a spring like the #SSF-106-40 will compress down to half…

For the front axle of your 2006 Ford Class C E-450 motorhome we have the SumoSprings kit part #SSF-106-40 as only option. This will give your RV an additional 500 lbs of suspension support. The different colors of kits mostly relates to different…
