Want Extreme Looks and Durability For Your Jeep JL?

Fab Fours Now Has The Jeep JL Grumper For All You Jeep Lovers!

The Grumper steel off-road replacement bumper and grille is a Fab Fours favorite due to its aggressive look, innovative design, and extreme durability.

Now available for the Jeep JL in both standard and full width, you will turn heads when you customize your Jeep with a Jeep JL Grumper!

The amazing Grumper was originally designed for The Legend, one of our outstanding project vehicles.

The response to this bumper and grille combo was so overwhelming that Fab Fours started making it available for Jeeps first and then other trucks.

When the new Jeep JL came out, the Grumper was redesigned for the JL and quickly became one of the most aggressive-looking steel bumpers on the market!

For you Jeep JL owners who want extreme style, durable protection, and flexibility all in one, the Jeep JL Grumper by Fab Fours provides that and more:

  • Total Customization for A Truly Unique Appearance – The Grumper has parts that can be included or removed as you like and the ability to be painted any color to create your own personal vehicle color scheme. It accepts additional lights and can be easily modified to create an “angry eye” front end look!
  • Functional Heavy Duty Bumper – With a noteworthy design like no other, the Grumper actually protects the entire front end. This heavy-duty winch bumper is made from 11g steel and integrates seamlessly with many other Fab Fours custom parts like the Grumper fenders. This is one tough bumper that will protect your Jeep JL!
  • Unique Innovative Design – The Jeep JL Grumper has the same aggressive look as our Legend project car yet still gives you complete customization options. In standard and full width options, each style fits the JL like OEM equipment!

You take pride in your Jeep JL Wrangler, so when you take it off-roading, it should look great and be prepared for anything you encounter on the trails.

With the JL Grumper by Fab Fours, you are assured of having the superior protection you want for your Jeep JL.

This heavy-duty, fully customizable Grumper affords full protection with a style that is like no other Jeep JL – it is yours alone!
