Trailer Axle 8-12K Owners Manual FULL
Double-Eye Leaf Springs
Double-eye leaf springs have eyes at either end of the spring assembly with nylon bushings to assist in
preventing wear. U-bolts hold the springs to the axle with a plate.
The articulation of this suspension occurs when the eyes rotate on the wear surfaces provided in eyes of the
springs and on the equalizers. This suspension is also available in single and multiple axle configurations.
In trailers with 2 or more axles, the additional movement is maintained by an equalizer. This feature allows
for even load handling from axle to axle.
Double-eye suspension systems are available on 8,000 lb. axles. Tandem and triple axle mounting kits are
available for both 33” and 35” axle spacing.
Slipper Leaf Springs
Slipper springs have a loop eye formed on one end and a reverse radius on the other. The front eye is
secured to either the front hanger or rear of the equalizer with a bolt and nut. The slipper end rides against a
wear block located in either the front of the equalizer or the rear hanger.
A keeper bolt or strap is placed under the slipper end to contain spring when the trailer is lifted off the
ground. 8K tandem and triple axle attaching kits are available for both 33.5” and 36” axle spacing. 10K and
12K tandem and triple axle kits are also available for 42.25” or 48.25” axle spacing.
