Archive's Stealth HD U-Bolt Flip Kit

Take control of your truck's rear suspension with our Stealth HD U-bolt flip kit. Designed to fit stock springs from 2.375" to 2.5" wide, this kit keeps your leaf packs tight and prevents them from rotating out of alignment—even on the toughest trails.

One of the key benefits of our kit is its design. It allows you to remove your bump stops without having to remove the U-bolts and plates, saving you time and hassle when you're working on your suspension.

If you purchase this kit, you'll also be eligible for a discount on future replacement U-bolts.

Optimize Your Suspension with Archive Speed Bumps

Options 3 and 4 of our kit feature our Archive Speed Bumps, which we engineered to give you the ultimate ride.

• Soft engagement and max bump travel for a smooth, progressive feel.

• No center hole to trap water, which can lead to rust and damage.

• Securely fastened with two tough 3/8" bolts.

• Made from high-strength steel, which is 30% stronger than the competition.

Note: The spring center bolt threads must be trimmed to a maximum height of 1/2" above the spring.

What's Included

• Two HD U-bolt plates with a kick-out for air bumps. These are powder-coated and made from high-strength HSLA 50ksi steel (30% stronger than mild steel).

• Four HD 9/16" round U-bolts (3 1/4" x 8 1/2") that can clamp leaf packs up to 3.5" thick (trim to fit).
