The Critical Role of Center Bolts in Leaf Spring Assemblies

Center bolts may appear simple, but they are structurally essential components within a vehicle’s leaf spring suspension system. At Tekay Automotive, we manufacture center bolts with the same attention to precision and quality as our U-Bolts and spring bushings.

These bolts pass through the center of the leaf spring pack, clamping all layers together to maintain alignment and ensure proper operation under dynamic loads.

🔍 Key Functions of Center Bolts:

  • Clamping Force: Keeps leaf spring layers compressed and in position

  • Axle Location Support: Works with U-Bolts to fix the axle in the correct spot

  • Prevents Shifting: Avoids lateral or longitudinal movement during braking and acceleration

  • Supports Load Distribution: Plays a part in ensuring the spring functions evenly under stress

 

At Tekay, we produce center bolts from high-tensile steel, offering superior strength and durability. Combined with our in-house production and quality checks, we guarantee that each center bolt delivers performance in line with OEM expectations.

From heavy-duty trucks to trailers and agricultural equipment, Tekay center bolts form a critical link in safe, high-performing suspensions.
