Leaf springs are an integral part of your trailer suspension system. The double-eye spring is suspended at the ends by hangers that attach to its eye or, in the case of tandem-axle or triple-axle systems, into hangers in the front and rear and an equalizer or equalizers in the center. To determine the type of hangers or hanger kit you need, you must know the specific type of leaf spring you have, as well as your axle diameter and capacity. Depending on the hanger kits used with them, springs can be configured to work for single-, tandem- or triple-axle applications.
Please Note: To ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs.

Today well gonna be taking a look at part number PR4, the 4-Leaf Double-Eye Spring for 4,800-lb Axles.Before you order a spring for your trailer, there are a few things you will need to know first. This spring measures 25 inches long by 1 -inch wide. You will need to know the springs half-length which is measured from the center of the eye mount to the center of the spring here at the leaf bolt. This spring has a 12 5/8-inch half-length. You will need to know the spring height. To get this height measurement, youll need to draw an imaginary line from the center of the eye mount on either side across.
From this line you can measure to the spring surface which will give you your spring height. In this case, it is 3 inches.Youll notice it has two 9/16 mounting eyes with nylon bushings within them. These nylon bushings help to prevent metal on metal contact while the spring is on the trailer.With its 4 leaves it has the ability to support 2,400 lbs. When you multiply that by two per axle, you get your 4,800-lb total capacity.And that does it for part number PR4, the 4-Leaf Double-Eyed Spring for 4,800-lb axles. .

Exact replacement for broken spring. Installed as expected, removing the old spring is difficult due to rusty bolts and such. Be sure you have tools capable for high torque16552

Every I ordered arrived on time. I installed the new springs, shackles and bolts on my boat trailer in about 2 hours. Most of the 2 hours was spent removing the old rusty bolts. All the new parts fit perfictly and seem to be of high quality. I was very satisified with my purchase.5782
