Will SumoSprings Trailer Helper Springs Increase Space Between Frame and Axle

Question

Question:

I’m considering some of your products but need some insight. I’m not trying to increase the payload of my tandem axle trailer but I’ve noticed when it’s loaded I have very little room for suspension travel and have noticed that the deck cross members have been contacting the axles. Will the sumosprings for under sling axles help with this? I should add I’m not attempting to overload my trailer or make a modification to do so!

The SumoSprings Trailer Helper Springs typically install compressed so they do tend to provide more space between the frame and axle in most cases but not by much and this is not really the goal of the system. If you don't have enough space between the frame and axle then this may be due to worn out leaf springs so I recommend checking this but I have attached the SumoSpring options below which are based on axle type and capacity.

SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 3K to 5K - Underslung part # TSS-106-40
SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 5K to 8K - Underslung part # SS33HR
SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 3K to 5K - Overslung part # TSS-107-40
SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 5K to 8K - Overslung part # SS26MV

We do not recommend moving from 7,000lb #e64SR to 8,000lb #DX74XR leaf springs as this creates a stiffer ride with more bounce. This causes more shock to transfer inside your RV which can cause damage to the trim and electronics. Instead I recommend…

No, you would definitely need to upgrade the entire axle, to include the axle beam and spindles, not just all of the other components to get a 5,200 lbs axle. If you could send me a measurement of your Hub-face-to-hub-face length and your…

Hey Phil! Thanks for getting back to me with those measurements! We have a leaf spring that is an exact replacement but I am guessing it's the pricey one you referenced. It is the 4-Leaf Double-Eye Spring for 4,400-lb Trailer Axles - 25-1/4"…

Hey Michael, at this time the unique bolt pattern of your current pin box does not have an aftermarket replacement. Maybe a more cushioned fifth wheel hitch could help but the A25 isn't a rough riding hitch generally speaking. You could look into…
