The 3" Length is also very common on trailers with 2,000 lb and 3,500 lb axles with 1 3/4" Wide Leaf Springs.These 9/16 inch Spring Bolts can be purchased along side the leaf springs and equalizer bars. These bolts are raw steel, and are splined to allow a secure fit. The nuts are self locking and must be installed with the grooves(shown) out. Feel free to check the measurements on your spring bolts before purchasing or call us if you need any assistance. This Grease-able Version allows the user the ability to apply grease to the inner sleeve where the bolt makes contact with the Leaf spring. This improves suspension function and reduces friction. In addition, the application of Grease acts as a corrosion barrier which helps increase the life span of your trailer bolts.
