Grade 8 Strength Where It Counts

Grade 8 steel is the standard for high-stress fastener applications, and leaf spring U-bolts are among the highest-loaded fasteners on a truck's suspension. Using hardware rated to that specification means the leaf spring pack stays properly located on the axle under load, over rough terrain, and during towing. Those are the conditions where a DRW or heavy-duty Ram is most likely to be working hard. Undersized or lower-grade U-bolts can stretch or loosen over time; grade 8 hardware resists that.

Corrosion Resistance Built In

The black E-coat finish applied to each U-bolt provides a barrier against moisture and road salt. That protection is relevant for any truck that sees winter roads or off-pavement use. Because U-bolts sit close to the axle and are difficult to inspect regularly, a corrosion-resistant finish reduces the risk of hidden degradation between service intervals.

Complete Hardware Included

The kit ships with the U-bolts, nuts, and washers needed for installation, so no separate hardware sourcing is required. The 17-inch length is sized to work with a variety of leaf spring and rear block combinations on the covered platforms.

Features

• 17-inch length: compatible with a variety of leaf spring packs and rear block heights on covered fitments
• Black E-coat finish: corrosion-resistant coating for extended service life
• Complete kit: U-bolts, mounting nuts, and washers all included

Specifications

Who This Is For and Isn't

This kit suits owners of a 1999–2010 Ford F-350 Super Duty with dual rear wheels, a 2003–2013 Dodge Ram 2500, or a 2003–2012 Dodge Ram 3500 who are replacing U-bolts as part of a leaf spring, add-a-leaf, or rear block installation, or replacing worn or corroded factory hardware.

This kit does not fit single-rear-wheel (SRW) F-350 variants; per Application Note #702, the F-350 fitment is limited to DRW/Dually configurations only. It is not designed for front suspension applications.

Common Questions

Does this kit fit a single-rear-wheel F-350?

No. Per ICON Application Note #702, this 17-inch U-bolt kit is compatible only with the Ford F-350 Super Duty in Dual Rear Wheel (DRW/Dually) configuration for model years 1999–2010. Single-rear-wheel F-350 variants are not a supported fitment for this kit.

What hardware is included in the kit?

The ICON 17-inch U-bolt kit includes the U-bolts themselves along with all mounting nuts and washers needed for installation on the covered Ford and Dodge platforms. No additional fasteners need to be sourced separately.

Will these U-bolts work with an add-a-leaf or rear lift block?

The 17-inch length is designed to be compatible with a variety of leaf spring pack and rear block configurations on the 1999–2010 Ford F-350 DRW, 2003–2013 Dodge Ram 2500, and 2003–2012 Dodge Ram 3500. Confirm the specific block height and spring pack thickness are within the range your installer expects for this length before ordering.

What does the E-coat finish do?

The black E-coat (electrocoat) finish on each U-bolt provides a corrosion-resistant barrier against moisture and road salt. This helps protect the hardware from degradation during the extended periods between suspension service intervals typical of heavy-duty truck use.
