DOUBLE EYE TRAILER LEAF SPRINGS
TRAILER LEAF SPRINGS (DOUBLE EYE)
Trailer leaf springs generally do not require maintenace or service other than rinsing off when used in salt water. Lubricant can be applied to moving parts for simple care. Leaf Springs are the most important part of a trailers suspension system. Double eye leaf springs attach at the eyes by spring hangers, or in the case of tandem or triple axle suspensions, into spring hangers located in the front and rear and equalizer(s) in the center. When determining the type of spring hangers or hanger kit you need, you must know the type of leaf spring you have and the trailer axles diameter and capacity. Trailer Leaf Springs can be configured to work with single, tandem or triple-axle suspensions.
An inside diameter of 9/16" is the most common size for trailer leaf springs. Some older running trailers used 1/2" bushings and bolts.
1-3/4" Wide Trailer Leaf Springs are manufactured using HD spring steel. Double Eye springs come complete with 9/16" I.D. nylon bushings.
