How to Install a MBRP Front Stubby Non Winch Bumper on your 07-18 Jeep Wrangler JK; 2018 Jeep Wrangler JL

1. Remove the OE [Original Equipment] splash guard by removing the push rivets. Refer to Figure 1. 

2. Remove the OE bumper by first unplugging the driving lights and then unclipping the wiring harness from the bumper crash bar. Then remove the eight nuts located on the frame horns. Once the eight nuts are removed, remove and retain the four backer plates. The bumper assembly will slide off. Remove the OE driving lights from the OE bumper. Refer to Figure 2.

3. Remove the two push rivets from the plastic filler panel between the OE bumper and the grill using a Phillips screwdriver to remove the core, and then pulling the rivets out. The core may spin without backing out. If this happens, try to pry up on the head of the rivet with a flat screwdriver while unscrewing the core. This will help the rivet pinch the threads of the core allowing removal. Once the rivets are out, remove the panel. This panel will not be reused. Refer to Figure 3.

4. The crossbrace connecting the LH and RH frame horns needs to be removed to provide clearance for the Bumper. Separate the crossmember using a sawsall or similar tool to cut the tabs as shown at each frame horn. Use a grinder to smooth the cut edges and seal with paint. Refer to Figures 4 and 5.

1. Install the Driver and Passenger Support Brackets as shown above with the supplied ½”x1” Hex Bolts, ½” Washers, and ½” Hex Nuts. The brackets must be installed exactly as shown with the lower tab facing the center of the vehicle and the open area at the upper through hole facing rearward. If the brackets are installed backwards the lower tabs will not line up with the lower face of the Bumper. Leave all fasteners loose enough to allow adjustment of the brackets in the following steps. Refer to Figures 1 and 2.

2. Mount both of the previously removed OE Driving Lights into the supplied OE Driving Light Brackets using the supplied #8x5/8” Machine Screws, #8 Washers, and #8 Nyloc Nuts. Refer to Figure 3.

3. Install both OE Driving Lights into the Bumper using the supplied ¼”x3/4” Hex Bolts, ¼” Washers, and ¼” Hex Nuts. Refer to Figures 4 and 5. 

4. With help from a friend, install the Bumper onto the Jeep by sliding the assembly onto the frame horns and over both Driver and Passenger Support Brackets. The assembly can be temporarily pinned in place by installing the two ½”x1.5” Hex Bolts with ½” Washers through the top surface of the Bumper into the Driver and Passenger Support Brackets. Some alignment of the brackets may be required. Refer to Figure 6.

NOTE: if you have purchased the optional Light Bar Kit #131128, it should be installed before Step 4. 

5. Install the remaining fasteners to secure the Bumper starting by inserting the eight ½”x2.5” Hex Bolts, and ½” Washers through the front face of the Bumper. Secure on the backside by first reinstalling the OE backing plates followed by the supplied ½” Washers, and ½” Hex Nuts. Leave the fasteners loose. Do not tighten yet.

6. Install the two supplied ½”x1.5” Hex Bolts and ½” Washers in the lower face of the Bumper. These bolts will pass through the lower tabs of the Driver and Passenger Support Brackets. Some alignment of the brackets may be required. Secure with the supplied ½” Hex Nuts and ½” Washers.

7. Secure the two ½”x1.5” Hex Bolts and ½” Washers installed in Step 4 using the supplied ½” Hex Nuts and ½” Washers. Once all mounting fasteners are in place, tighten all ½” fasteners to 60 ft-lbs in the following sequence.

- 8 bolts in the front face of the Bumper.
- 2 bolts in the top face of the Bumper.
- 2 bolts in the bottom face of the Bumper
- 6 bolts connecting the Driver and Passenger Support Brackets to the Frame.

8. Reconnect the Driving Light wiring and secure to prevent chaffing of the wiring.
