Spring Assy, Black, 9/16" x 3"

The Spring Assy, Black, 9/16" x 3" is a spring center bolt and nut assembly measuring 9/16-inch diameter by 3-inch length in black finish, available at Skipper B Trailers in Westwego, Louisiana. This bolt passes through the center of the leaf spring pack and the center hanger bracket, serving two critical functions — it holds all the leaves in the spring pack aligned together, and it locates the spring precisely in the center hanger so the axle stays in the correct position under the frame. The 9/16-inch diameter handles the clamping load that holds multi-leaf spring packs together under the constant flexing that suspension travel produces, and the 3-inch length accommodates the specific spring pack thickness and center hanger depth for this application. The black finish provides basic corrosion resistance for standard painted trailer frames.

Louisiana trailer owners servicing leaf spring suspensions encounter the center bolt when replacing springs, rebuilding spring packs, or diagnosing axle alignment issues. A sheared center bolt allows the individual spring leaves to shift laterally — the leaves fan out instead of staying stacked, the spring loses its ability to support the axle load properly, and the axle can shift position on the spring pack. On the rough roads between Westwego, Marrero, Harvey, Gretna, and the potholed parish roads throughout Jefferson Parish, a sheared center bolt turns a functional suspension into a sloppy, misaligned mess that affects tracking and tire wear on Interstate 10, Highway 90, and the Westbank Expressway. The center bolt also takes shear stress every time the trailer brakes — the braking force tries to push the axle forward against the spring, and the center bolt resists that force at the hanger. Replacing the center bolt during any spring service ensures the spring pack stays aligned and the axle stays located. Whether you're Fishing Fanatic Frank replacing a broken center bolt during a spring swap, a marine repair shop stocking spring hardware for customer trailer service in Greater New Orleans, a DIY mechanic rebuilding a leaf spring suspension, or any trailer owner performing spring pack maintenance, this assembly provides the bolt and nut together.

At $5.99, this spring bolt assembly provides both the bolt and nut for a complete spring center installation. The 9/16-inch by 3-inch size fits specific spring pack and center hanger configurations. Black finish for standard painted trailers. Measure your existing bolt to confirm diameter and length match. Perfect for spring replacement, spring pack rebuilds, center bolt replacement, and leaf spring suspension service throughout Southeast Louisiana.
