How do I measure for the right U-bolt size?

Measure axle diameter, spring stack height, and the required leg length (from inside the bend to the end of the threads). Choose a diameter and length that match those dimensions and your bracket thickness.

Should I replace nuts and washers when installing new U-bolts?

Yes. U-bolt nuts and washers experience fatigue over time. New hardware helps maintain clamping force and reduces the risk of loosening under load.

Do these U-bolts come with a warranty?

All U-bolts and related hardware include a lifetime structural warranty covering material and manufacturing defects.

When should I recheck torque after installation?

Recheck torque after the first 100 miles and during routine maintenance. Always follow your vehicle service manual for torque values and patterns.

What finish should I pick for wet or salty climates?

Zinc-plated or black-oxide finishes add corrosion resistance, making them a smart choice for trucks and SUVs driven in wet, snowy, or coastal conditions.
