They do not have leaf springs that are specifically designed for boat trailers that are used in salt water. Since the leaf springs will flex there is no kind of plating or coating that will stay attached to the spring. Also, the process that is used to plate or coat a part can use high temperatures that could cause premature failure of the spring.
As long as you get the leaf springs with the correct weight rating and the correct measurements to fit your boat trailer you should have no... view full answer...
I spoke with my contact from Roadmaster and she said that the steel used for the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers # RM-2460-2570 is from America.
Although American steel tends to be stronger, when it comes to leaf springs the biggest mistake people make is overloading them which does cause them to wear prematurely to the point of failure. No matter what kind of leaf springs you install on your trailer be sure that you stay within the weight ratings... view full answer...
The etrailer Leaf Springs we offer like the 5-Leaf Double-Eye Spring part # e34SR are very durable and have a great reputation for performance and longevity. In fact, we have hundreds of customer reviews on these leaf springs and most have given the highest rating possible. I am not sure which other leaf springs you are referencing but I can confirm the above are a quality option you can rely and depend on.
In regards to suspension enhancement, the Equa-Flex Cushioned Equalizers part... view full answer...
This 5-Leaf Slipper Spring # SP-106275 that you referenced is a 3,000 lb spring designed to be used on 6,000 lb trailer axles.
I went out into out warehouse to see if these were made in China, and I found the letters MCK stamped on the spring and that means it was made in China.
I attached an FAQ article on slipper spring trailer suspensions for you to check out also. view full answer...
Leaf springs like the # e84SR are made of high carbon steel. Each of the three leaves in this spring is 1/4-inch thick, so the overall thickness at the center is 3/4-inch, 1/2-inch as you move outward to the 2-layer section and finally of course 1/4-inch at the 1-layer section. Please refer to the linked photo that I prepared for you. view full answer...
The Trailer Leaf Slipper Spring, part number SP-040275, is not galvanized or coated it is a solid steel leaf spring. The leaf springs are shipped with a light coat of paint for rust protection but are not rust proof. Coating or treating the springs would not work because of the flexing and rubbing the springs are subject to under the trailer. The leaf springs can be painted but the paint will not last long with the constant flexing and road debris hitting them. The mounting hardware... view full answer...

According to Dexter Axle their leaf springs are made in the US so I've linked our selection of those for you to filter through. If you can let me know the length of leaf spring you're needing to replace I'd be more than happy to see if we have one that fits your application!
For example, the Dexter Axle Double Eye Leaf Spring # 072-017-00 measures 20-1/4" center-eye to center-eye when no tension is placed on it. view full answer...
The 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles # e34SR is made in China like all the leaf springs we currently carry. I have included an image of the tag on the spring showing its origin. view full answer...
I spoke with Malone and the Malone MegaSport Kayak Trailer part # MPG535 is USA made and assembled save for the leaf springs and wheels/tires. I don't think there are many leaf spring manufactures in the USA and I know there are only a few trailer tire manufactures. The trailer does have a five year warranty on the other hand so if anything were to go wrong with those parts then you would be covered. view full answer...
With the trailer towing up to 5,000-lbs you can replace both axles on your trailer with 2 sets of the Timbren Axle-Less Trailer Suspension System, part # ASR3500S04, and they will be more than sufficient. The system is designed to make the ride much smoother regardless whether you are hauling a load or not.
The progressive springs get stiffer as more weight is added but are always engaged to reduce rattle and bottoming out. The axle-less system does come with a 4-bolt brake flange installed... view full answer...
Unless your axles were custom made/modified, the 3" diameter will denote an axle in the capacity range of 5,200 pounds (like the Dexter # 6340624) up to 7,000 pounds (like the Dexter # 8327834). If there was a previous owner of your trailer, they may have upped them to a heavier capacity, but even some manufacturers will equip trailers with heavier duty parts than needed. Especially if it is a newer trailer. Demand has been much higher than supply recently so I have seen a couple trailers... view full answer...
Typically, when the outside edges of a tire are showing wear its because the tires are under-inflated. The solution is to inflate the tires to the maximum pressure listed on the sidewall.
Now if the outside of tires have what looks like gouges are taken out of the rubber most likely it is broken suspension components or its a bent axle or spindle.
Unlike passenger vehicle tires, you always want to have trailer tires inflated to the maximum tire pressure for the best performance and wear.
