Motobilt Crusher Series vs Micro Series — Which Rear Bumper Is Best for Your Jeep JL/JLU?
Upgrading the rear bumper on your Jeep Wrangler JL or JLU does more than change the look of your Jeep — it improves departure angle, adds recovery options, increases protection, and lets you customize your Jeep’s capability based on the way you actually use it.
Motobilt offers two core rear bumper platforms for the JL/JLU:
-
Crusher Series Rear Bumper (4 configurations)
-
Micro Series Rear Bumper (with optional Rear Lower Corner Armor add-on)
Each offers unique benefits, styling, and functionality. This guide breaks down all the options so you can choose the perfect setup for your build.

- Laser-cut and CNC brake formed in the USA
- 3/16-inch high-strength steel throughout
- Precision fit to the JL/JLU body
- Designed by wheelers for real trail abuse
- Compatible with factory JL/JLU features
- Clean, modern, high-clearance styling

Micro Series Optional Add-On: Rear Lower Corner Armor (MB2184)

Motobilt’s Rear Lower Corner Armor is the perfect complement:
Benefits:
-
Adds thick 3/16" steel protection along the most vulnerable rear edge
-
Wraps around the lower corner edge for protection
-
Matches the Micro bumper’s lines

If you're running the Micro bumper, this armor is highly recommended.
