MB1110 JT Gladiator Crusher Rear Bumper – Installation Instructions

Loosen the bolts holding the rock rail 

mounting brackets.  Do not remove the 

bolts.

If your vehicle is NOT equipped with the 

optional rear rock rocks, you will need the 

MB1111 Gladiator Rear Corner Supports to 

complete your installation.

Using a 16mm socket, remove the four (4) 

flange nuts from behind frame mounting 

plates.

With all fasteners removed & wiring 

disconnected, remove the factory rear 

bumper from the vehicle.

If your vehicle is equipped with optional 

rear tow hooks, remove these tow hooks 

now.

Using a cut off wheel, remove a small 

portion of metal above the factory 

receiver hitch (as shown removed).  Apply 

paint to cut edges of bare metal if desired.
