SumoSprings for 2018 Thor Vegas on Ford E-450 Chassis  

The SumoSprings kit I recommend for your 2012 Ford E-350 passenger van towing a 6,000 lb trailer is the part #SSR-130-47 as it provides 1,500 lbs of additional suspension support which will be a solid amount of support without making the ride quality…

For your 2015 Thor Four Winds E450 C-Class built on a Ford E-series chassis we do offer front suspension enhancement kits. These are rubber jounce springs (no air bags are available) or sway bar type items. The links provided will let you see both…

The 2,800 lb capacity of the SumoSprings Solo Custom Helper Springs #SSR-130-54 is for both. This is the weight capacity at 50% compression. These are confirmed to fit your 2018 Ford E-Series Cutaway.

With SumoSprings #SSF-106-40 installed on your 2017 Thor motorhome built on the Ford E-350 van chassis the springs will be engaged all the time. This means that the vehicle won't have the natural sag that it would with the stock bump stops and…

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 option for 4-wheel drive models but if you have a 4x4 then you can instead use…

Hi Jeff, I can give you a hand here with suspension upgrades for your 2023 Jayco Greyhawk 27U, though honestly I'd go a different route than the Timbrens #TFEF350 and #TFERSD you mentioned. They'll do their job, but my goodness they can be…

For a 2WD 2018 Ford E-350 Class C cutaway chassis I recommend the SuperSprings rear axle kit #SSR-130-54 which is rated for 2800-lbs. Kit #SSR-106-47-1 will be too stiff. Since a flat towed vehicle does not really load tongue weight on the Thor's…

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.
