Today well gonna be taking a look at part number PR424, the 4-Leaf Double-Eye Spring
for 3,000-lb Axles.Before ordering a spring for your trailer, there are a few things you
do need to know first. This spring measures 27 inches long by 1 inches wide. You do 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 13 -inch half-length. One measurement
you will need to do is to measure the spring height. To do that, youll draw an imaginary
line from the center of the mounting eye to the center of the mounting eye.
And using that imaginary line youll measure from it to the spring surface. In this case,
it is 2 inches.Youll notice that these springs has two 9/16 mounting points with nylon bushings.
These nylon bushings help to prevent metal on metal contact while the spring is installed
on the trailer.It does have 4 leaves in it giving it a 1,500-lb load capacity. When you
multiply that by two, you get your 3,000-lb total load capacity per axle.And that does
it for part number PR427, the 4-Leaf Double-Eyed Spring for 3,000-lb axles. .
