4 Pcs Leaf Spring Center Bolt - 5/16 x 4 Fine Threaded Leaf Bolts with Nuts-Universal for Truck/SUV/Trailer Leaf Packs

4 Pcs Leaf Spring Center Bolt - 5/16 x 4 Fine Threaded Leaf Bolts with Nuts-Universal for Truck/SUV/Trailer Leaf Packs

• Correct Size & Pack: Each bolt is 5/16" diameter x 4" length, sold as a pair and supplied with nuts for a ready-to-install kit.
• Fine-Thread, Cut-to-Length Design: Fine threads run most of the way down; any excess length can be trimmed after tightening for a clean fit.
• Ideal for Leaf-Pack Service: Recommended whenever adding/removing leaves or opening a spring pack—replace the center bolt for safety and reliability.
• Install Notes for Best Results: Clamp the spring pack with C-clamps before snugging the nut; some listings note these bolts are not hardened, so avoid over-torque. (Choose hardened/graded bolts for heavy-duty builds.)
• Wide Compatibility: Universal replacement where a 5/16" center bolt and ≤4" pack thickness are specified—commonly found on many trucks, SUVs, and trailers (verify hole size and length before ordering).
