SumoSprings Recommendation for 2020 Thor Axis on Ford E-450 Frame  

The SumoSprings I recommend for your 2004 E-450 Cutaway is part #SSF-106-40. These springs are progressive load springs which means they will stiffen as more weight is added to the front of your E-450. The springs work independently for offset loads…

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…

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 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…

For your 2014 Jayco 29d, I recommend using the Firestone Ride-Rite Air Helper Springs - Double Convoluted - Rear Axle #F2458 which will actually raise the frame when inflated to a higher psi versus just keeping it from dropping lower. Along with this…

Yes, those parts from SuperSprings will fit your 2023 Forest River East-to-West Entrada: - Front #SSF-106-47 - Rear #SSR-106-47-1 It is important to check and make sure you have 7" of clearance from your tire sidewall to the frame of your RV…

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…

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…
