20 inch Double Eye 3 Leaf Spring that is rated to 1850 lbs per spring. This would bring a pair of these 20 inch Double Eye Trailer Springs to 3700 pounds. These are common on 3500 lb trailer axles.  
Spring Measurements and Specs:
Eye to Eye Measurement  20 1/8 inches (Free Length Measurement)
-Does your spring measure slightly more than 20 inches, lets say 20 3/4 or so? You may have your trailer loaded, or the spring may be old and flattened out. It is not uncommon for leaf springs to measure longer than what the stock size is listed. 
Free Arch Measurement (see picture) 3 1/2 inches
-The free arch measurement is based off a stock, brand new spring. Your leaf spring will more than likely be flattened out, or possibly broken. 
Spring measures 1 3/4 inches wide
9/16 inch bushings come installed in the spring, 1/2 inch are available as an add on for this leaf spring.

These springs can be used on both square tube or round tube trailer axles on boats or land trailers. The only difference is in the style of U-Bolt Required to mount the spring to the axle. Check the condition of your U-Bolts and the required size and check our U Bolt Kits out here. Leaf Spring U-Bolt Kits. Available in raw steel, hot-dipped galvanized, and stainless steel. 

If you are planning on replacing the hangers, (brackets that are either welded or bolted to frame that hold leaf spring) and shackles (2 shackles towards rear of spring assembly for single per side or 4 in the middle for tandem trailer per side) We have single and double spring hanger kits available for Weld On assemblies that include all the necessary replacement hardware. Weld on assemblies are more common on non marine trailers.Spring Hangers
Boat trailers will commonly have bolt-on hangers or spring sliders.

Strong springs
I was very please with the delivery speed. It was difficult to find this length spring with this much load bearing capacity. These springs did the job where my last so called heavy duty springs failed miserably.

Perfect match
As with anything you buy on line there is always some reservation about fit. The advise on the web site is accurate and the products fit perfectly. Life is good when it all comes together. I must add, the best price, great web site, easy to find what I needed, and fast shipping... what more could on ole' boy ask for? Replaced (all) 4 leaf springs on a 7K Performance trailer with 3.5K axles and all the hardware as needed.

I was able to get a new axel and leaf spring for my trailer without having to talk with anyone and the shipping was fast. The quality of the parts were better than my originals.

20 Inch springs
Not much to say about these other than they fit perfectly and appear well built. Getting the old ones off was the hard part. Penetrating fluid and a cutting wheel comes in very handy!
