  • Description
This Marine Coated 20 inch Double Eye 3 Leaf Spring is rated to 1850 lbs per spring and coated for saltwater and freshwater use. The 3700 lb capacity for a pair of these leaf springs makes these a common option for 3500-pound capacity axles. The marine coated steel finish is suitable for land and boat trailers alike!

Spring Measurements and Specs:
Eye to Eye Measurement  20 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 1/4 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. 
-This Trailer Leaf Spring measures 1 3/4 inches wide
9/16 inch bushings come installed in the spring, these bushings are common on all types of trailers except boat trailers. If you are purchasing these for your boat trailer, you will need 1/2 inch bushings to be installed which are available as an add on for this product.  

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 Mounting Kits. Available in raw steel, hot-dipped galvanized, and stainless steel. 

Commonly when replacing leaf springs, the spring bolts may also be needing replacement. As stated before, if you are purchasing for a land trailer(not boat trailer) you will be using 9/16 x 3 inch bolts , if this is for a boat trailer, check out zinc plated or stainless steel spring bolts that measure 1/2 by 3 1/2 inches Leaf Spring Bolts and Bushings
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. Boat Trailer Suspension Parts
Boat trailers will commonly have bolt-on hangers or spring sliders.
