SUPERLIFT Suspension U-Bolt Kit - 4 Pack, Round 5/8" X 3-3/8" X 11", Zinc/E-Coat Finish, With Nuts & Washers

When you're installing a lift kit or replacing worn suspension components, you need strong, reliable U-bolts. This SUPERLIFT kit gives you four high-strength, round U-bolts made in the USA from low alloy steel with a yield strength of 90,000-115,000 PSI. The dimensions are 5/8-inch diameter, 3-3/8 inch inside width, and 11 inches long (thread length). They come with the necessary nuts and washers, and have a Class 2A National Fine thread.

They feature a durable anti-corrosion finish – either zinc or a black e-coat – to resist rust. These are essential for securely clamping leaf springs to your axle. Whether you're working on a truck, Jeep, or SUV, having fresh, grade-matched U-bolts is crucial for safety and performance. SUPERLIFT backs them with a limited lifetime warranty, so you can install with confidence. Just make sure these dimensions match your specific application.
