Question:
What is the difference between an 8K Dexter axle and a 7K Dexter Axle? What actually determines the weight rating? Is it just the leaf springs? Would there be any advantage of installing 8K springs on a 7K axle? Thanks!

Helpful Expert Reply:
Typically a Dexter 7k axle will have a diameter of 3 inches and an 8k axle will have a diameter of 3-1/2 inches. The thicker the axle the more weight it can handle. There really isn't an advantage to going with higher capacity leaf springs than needed. If the suspension is too stiff it doesn't really do it's job well as the ride would be rougher. Best recommendation I can make is to stick with the correct rated suspension you have on your trailer and then to not exceed the weight capacity of the trailer.
For a 7k rated leaf spring we have the part # e64SR which measures 24-7/8 inches in length.
