Trailer Leaf Spring Bolts and Bushings

Below are a selection of both leaf spring mounting bolts and leaf spring bushings. More commonly on Boat Trailers, you will see 1/2 inch diameter Leaf Spring Bolts used. They are typically the 1/2 inch by 3 1/2 inch Leaf Spring Bolts. However, in some cases boat trailers were designed to use 9/16 inch diameter spring bolts. We have both available for you in zinc plated and stainless steel. Check the diameter and length bolt your require to ensure proper fit. 
Leaf Spring bushings are nylon and are designed to be installed into the eyes of your trailers leaf springs. It is very important to have the proper size leaf spring bushing installed in the eye of your spring to prevent excess movement of your leaf spring mounting bolt. We have seen Leaf Spring Mounting Bolts wear away at the eyes of trailer leaf springs because fresh and proper sized bushings were not installed. Check the condition of your leaf spring bushings when replacing leaf spring mounting bolts.
