Question:
Original 3500# axles. Custom made trailer 20+ years old. Will a bit heaver spring fit - like the 4800# spring. I am in Afghanistan, trailer is in Arizona. The 25.25 eye to eye dimension looks to be common. Thanks

Expert Reply:
If the measurements on your trailer match the 4-Leaf Double-Eye Spring, part # PR4B or part # PR4, they will bolt up to your trailer.
My contact at Redline informed me that the heavier 4-Leaf Double-Eye Spring, part # PR4 will work, but it will give you a rougher ride. Also the weakest link on the trailer will be the 3,500 lb axles when using the 4,800 lb leaf springs.
It is recommended to use the Leaf Springs For 3,500 lb Axles, part # PR4B for your trailer with 3,500 pound axles.
Installing a larger capacity leaf spring like part # PR4, will not increase the capacity of your trailer. You will want to stay within the weight capacity limitations of your trailer.
