What Is the Correct Torque for Trailer U-Bolts?

A properly torqued U-bolt is designed to stretch slightly, which creates a spring-like clamping force. This force acts much like a spring clamp, ensuring the suspension components remain tightly secured together under load and during road vibrations.

For 1/2-inch U-bolts, which are the most commonly used size on Venture Trailers, the recommended torque specifications range between 45 ft/lbs and 70 ft/lbs. Applying torque within this range allows the U-bolt to maintain proper preload without over-stretching or under-clamping, both of which could compromise suspension integrity.

• Under-tightening can result in loose suspension components, uneven wear, or even failure while towing.

• Over-tightening may overstress the U-bolt, leading to premature fatigue, thread damage, or breakage.

Routine inspection and re-torquing are also essential, since U-bolts may relax slightly after initial installation due to settling of suspension components.
