Are Trailer Leaf Spring Weight Capacities Listed Per Axle or Spring

Question:

is the capacity of leaf springs rated for the pair or individually? 3500lb spring? I have a 19ft bay boat with a 150 hp. My springs have gone completely flat and everything is rusted so I cant read anything on the trailer. It has the tapered spindles and hub assembly that I routinely replace/commonly bought at orielys or advanced. Im pretty sure they are 3 or 4 leaf. I want to replace the springs, bolts, ubolts Thank you for your time.

The leaf springs we carry like the part # e54SR are rated by the axle capacity they were intended to be used on. So this spring is designed for a 3,500 lb axle. It has an individual spring capacity of 1,750 lbs.

To pick out the u-bolts you'd need I'd need to know the diameter of your axles. Most likely it's 2-3/8 inch so you'd need the # SP01-040 for the U-bolts and then for plates # TRTP238175. Then for new shackle bolts you'd just need the # 126B2 and you'd be set.
