SHOP NUTS, BOLTS & LEAF SPRING ACCESSORIES HERE!

ATS Springs offers a complete line of leaf spring nuts and bolts designed to keep your suspension safe, aligned, and performing at its best. Using the right hardware is critical for all leaf spring installations, whether on light-duty trucks, heavy-duty pickups, or vans.

Hanger Mounting Bolt Kits
Attach leaf spring hangers to the truck frame using Grade 8 bolts, locknuts, and washers. These bolts replace rivets or worn hardware for stronger, safer suspension mounts and improved alignment.

Spring Eye Bolt Kits
Designed for the spring eyes at each end of the leaf spring. Grade 8 bolts provide superior tensile strength and torque retention, reducing stretching and keeping your spring pack securely aligned. Metric sizes are available for select applications.

Leaf Spring U-Bolt Kits with Deep Nuts
U-bolts hold the leaf spring to the axle, while deep nuts provide additional threads for proper torqueing. Available in round, square, and semi-round bends, these kits prevent spring movement and maintain alignment under heavy loads. Old U-bolts should never be reused due to fatigue and stretching.

Leaf Spring Center Bolts (Center Pins)
Center bolts align individual leaves in the spring pack and prevent lateral movement. Available in standard and special head styles, these bolts keep your leaf spring working as a single, reliable unit.

U-Bolt Washer Kits
Thicker washers sit under U-bolt nuts for greater torque distribution and to protect spring and axle surfaces. Prevents loosening and ensures durability under repeated heavy-duty use.

U-Bolt Deep Nut Kits
Extra-thread nuts that allow for proper torqueing on deep U-bolts, commonly used in heavy-duty trucks and vans.

Clip Bolt Kits
Used with leaf spring clips (Kwik clips), these bolts keep individual leaves aligned and prevent squeaks, shifting, or uneven wear. Most can be installed without removing the leaf spring.

Why Grade 8 Hardware Matters
Grade 8 nuts and bolts are stronger, more durable, and better able to handle torque, load, and vibration than standard hardware. Using top-quality hardware helps:

• Maintain leaf spring alignment
• Prevent frame or axle damage
• Improve vehicle handling and safety
• Extend suspension component life

Trust ATS Springs for all your leaf spring hardware needs, whether you’re replacing a single bolt or installing a full suspension kit. Proper hardware ensures a safe, smooth, and long-lasting leaf spring installation.
