TRA-2728

3 LEAF TRAILER SPRING

This is a 3-leaf trailer suspension spring designed for heavy-duty trailers with a capacity of 11,200 lbs. It serves as a critical component of the trailer's suspension system, absorbing road shock and supporting the load weight over the axle. The spring features hook ends (HK-1 type) on the top leaf at both the short and long ends, eliminating the need for standard eye bushings. You would typically replace this spring when the original is broken, sagging, or fatigued, which can cause uneven tire wear or poor ride quality, and it is recommended to replace springs in pairs to maintain even suspension geometry.
