Grade-8 Strength Where It Counts

Grade-8 steel is the highest common SAE bolt grade for automotive hardware, meaning these U-bolts are rated for the clamping loads a heavy-duty rear suspension demands. Properly torqued grade-8 U-bolts resist loosening under the repeated flex and shock loads that come with towing, hauling, and off-road use, which are the conditions F-250 and F-350 owners encounter most.

Corrosion Resistance Built In

The black E-coat (electrocoat) finish bonds to the steel surface before any topcoat, reaching into threads and recesses that spray coatings miss. On a rear axle exposed to road salt, mud, and water, that base-level protection matters for long-term hardware integrity, particularly on a component that must be removed and retorqued any time the rear suspension is serviced.

Complete Hardware Included

The kit ships with U-bolts, mounting nuts, and washers, so no separate hardware sourcing is needed to complete the installation. The 12-inch length is compatible with a variety of leaf spring packs and rear block heights used on these Super Duty applications.
