This Trailer Leaf Spring is referred to as a Reverse Curve Spring. When determining if you have a reverse curve spring, look at the rear of your spring to determine how your spring is mounted. Typically, on a reverse curve spring set up on your boat or land trailer, you will notice the spring bolts directly into a "hanger" directly with a single bolt. The front eye of the spring will also be bolted into the "hanger" with one single bolt.
The spring action is caused by the motion of the spring sliding inside of the hook of the spring along the spring bolt.
In some cases noticing you have a reverse curve spring is difficult because of corrosion around the rear "curve", making it appear that the spring is indeed closed.
This reverse Curve Trailer Leaf Spring measures 26 1/4 from center of front eye to center of rear curve. Keep in mind that springs do stretch overtime because of age and weight on the trailer.
This spring has 4 leafs, giving it a carrying capacity of 2350 lbs per spring, a total of 4400 lbs for a pair of springs. This Reverse Curve Trailer Spring is 1 3/4" Wide.
The Free Arch Measurement of this Leaf Spring is 3 1/2 inches stock
