Grade 8 Steel Where It Counts

Grade 8 is the highest common SAE bolt grade for automotive fasteners, meaning these U-bolts are rated for the clamping loads a heavy-duty leaf-spring rear suspension generates under load and off-road stress. Using hardware below that grade risks spring walk or axle shift, both of which affect steering and braking. Specifying grade 8 here removes that variable.

Corrosion Resistance Built In

The black E-coat finish is an electrodeposition primer applied before the hardware ships, giving the steel a uniform barrier against moisture and road salt. On a rear axle that sees mud, water crossings, and winter roads, a bare or zinc-plated U-bolt will surface-rust quickly; the E-coat extends service life without requiring additional treatment at install.

Complete Hardware Included

The kit includes the U-bolts, nuts, and washers needed for installation, so no separate hardware order is required. The 15" length is compatible with a range of leaf spring and rear block combinations used on these platforms, giving flexibility when pairing with add-a-leaf packs or lift blocks.
