Peterbilt 379 Bumper Flip Kits

Frequently Asked Questions About Peterbilt 379 Bumper Flip Kits

What is a bumper flip kit and what does it do?

A bumper flip kit is a set of mounting brackets and hardware that changes the angle or position at which your bumper attaches to the frame. On a Peterbilt 379, these kits are typically used to tuck the bumper closer to the grille and frame rails, eliminating gaps and giving the front end a tighter, more custom look, especially after installing a bumper that was not originally designed for that specific frame height or setup.

Will a flip kit fit my specific 379 without additional modification?

Most flip kits are designed to work with standard Peterbilt 379 frame dimensions, but frame height, hood style, and any prior bumper modifications can affect fit. Always compare your truck's bumper mounting bolt pattern and frame width to the kit's specifications before ordering, and check whether the kit is designed for your particular bumper style, since flip kits are often matched to a specific bumper brand or shape.

What material and finish options are available?

Bumper flip kits are commonly available in painted or powder-coated steel and, on some kits, stainless steel or chrome-plated finishes. Steel brackets are generally chosen for strength and are painted to match the bumper or cab, while chrome or polished finishes are more common on show trucks looking for a fully polished front end.

What tools and skills are needed to install a flip kit?

Installation typically involves removing the existing bumper brackets, positioning the new flip brackets according to the kit's instructions, and re-bolting the bumper in its new location. Basic hand tools, a socket set, and an extra set of hands to support the bumper during removal and reinstallation are usually all that is required. Some fitment adjustment may be needed depending on your truck's exact configuration.

Will a flip kit affect headlight, air line, or wiring connections?

Changing the bumper's position can shift the length needed for air lines, wiring harnesses, and any lights mounted to the bumper. Before installing a flip kit, check that your existing lines and harnesses will still reach their connection points, and be prepared to use extensions or reroute wiring if the bumper is moved closer to the frame.
