Peterbilt 389 Glider Bumper Flip Kits

Frequently Asked Questions About Peterbilt 389 Glider Bumper Flip Kits

What does a glider bumper flip kit actually do?

A flip kit is a set of brackets, hinges, and hardware that allows your Peterbilt 389 glider-style bumper to tilt or swing forward instead of being permanently bolted in a fixed position. This gives you direct access to the radiator, grille, and front-end components for cleaning, inspection, or repairs without having to fully remove the bumper each time.

Will this kit fit my existing glider bumper, or do I need a specific bumper to use it?

Flip kits are designed to work with standard Peterbilt 389 glider-style bumpers, but fitment can vary based on the bumper's mounting points, thickness, and overall design. Before ordering, check the listed compatibility details for the specific kit and compare them to your bumper's specs. If you're unsure, contacting our team with your bumper's make and dimensions is the best way to confirm a proper fit.

What material and finish options are available for the flip kit hardware?

Most flip kits are built from heavy-duty steel or aluminum components designed to handle the repeated movement and weight of a glider bumper. Finish options typically include raw steel, powder coat, or chrome-plated hardware, depending on the specific kit. Choosing a finish that matches your existing bumper and trim helps keep the front end looking consistent.

Is installation something I can do myself, or does it require a professional shop?

Many owner-operators and DIYers install flip kits themselves using basic hand tools, as the hardware generally bolts into existing or predrilled mounting points. That said, because the bumper is heavy and needs to be properly supported during installation and operation, having a second person or shop assistance is strongly recommended. Always follow the specific instructions included with your kit.

Does adding a flip kit affect ground clearance, weight, or DOT compliance?

A flip kit itself adds minimal extra weight and is not intended to change your bumper's height or ground clearance when in the closed, locked position. However, any modification to the front end should be checked against your state's regulations and your fleet's specific requirements, especially regarding bumper height and lighting placement, to ensure everything remains road-legal after installation.
