Recommended Superspring SumoSprings For 2007 E450 Class C Motorhome RV  

Published 04/10/2017



Question:

And for another good question: I was originally looking at the Ultra-Fab #UF48-979033. This has a weight of 51 lbs. and has been rated for rear carrier on RV and Trailer. That would give me an option. Thoughts? Also, Depending on the trip, I may not have the bike on the front of the RV. What will the characteristic be with the 1000lb rated SumoSprings assuming there will be no weight or a bicycle rack on the front?

The only front mounted hitch confirmed to fit your 2007 E450 Cutaway motorhome is the Draw-Tite Front Mount Trailer Hitch Receiver - Custom Fit - 2" # 65001. This hitch has a maximum 500 lb vertical load. For a motorcycle carrier, I recommend the etrailer Motorcycle Carrier w/ Ramp for 2" Hitch - 76" Long - Steel - 500 lbs # e98873 which weighs about 58 lbs leaving you a capacity of 442 lbs for your motorcycle. The Ultra-Fab # UF48-979033 would also work, weighing in at 51 pounds.

For your vehicle front suspension, I recommend using the SumoSprings Solo Custom Helper Springs - Front Axle # SSF-106-47 with the 1000 lb capacity. This will make sure you aren't at maximum support capacity when carrying the bike so there won't be as rigid a ride.

The Ultra-Fab Dirt Bike Carrier for 2" Hitches - With Ramp - 80" Long - 500 lbs # UF48-979033 is a great option for your front mounted hitch. I recommend using an anti-rattle locking pin with this carrier like # 63232 to hold this carrier snug. The 1000 lb rated SumoSprings will compress and add more rigid support as weight is added. Without the added weight, you shouldn't notice much difference on the front of your Motorhome unless you hit a significant pot hole causing the springs to compress and become more rigid. Even in this case, they will help your factory suspension. You won't have significant increase in kick from the 500 lb capacity springs to the 1000 lbs springs.
