Powder Coating and Installing an Off-Road Bumper on the XJ Cherokee
The Core 4x4 shop XJ Cherokee has been through a lot already — a 4-inch lift kit, 35-inch tires, a long arm upgrade, a WJ knuckle swap, and a fresh Rhino Line. But it still looks incomplete without a proper front bumper. In this build video, Spence and Marissa partner with Dirtbound Off-Road to sandblast, powder coat, and install a welded front bumper with frame braces that give the XJ unibody the structural support it actually needs.
Fitment: Jeep Cherokee XJ 1984–2001
Where the XJ Build Stands
Before this episode, the shop XJ Cherokee had already gone through some serious upgrades:
- 4-inch lift kit with Core 4x4 components
- 35-inch tires
- Long arm upgrade — replacing the factory short arms with adjustable long arms
- WJ knuckle swap — the big brake and steering upgrade
- Rhino Line — full exterior bed liner to cover the sun damage and rust
The Jeep runs and drives, but as Spence puts it, the front end is “looking sad” without a bumper. Today fixes that. Core 4x4 has partnered with Dirtbound Off-Road, and the plan is to showcase one of their XJ front bumpers — powder coated orange to match the build’s color theme.
The Dirtbound Off-Road Bumper
Dirtbound Off-Road is a Minnesota-based company that designs and manufactures their own products. For this build, Core 4x4 went with the welded version of the bumper rather than the DIY weldable kit. Key features:
- Tube-style front bumper — clean lines with a stinger hoop and integrated light bar mount
- Frame braces — included in the kit to reinforce the XJ’s thin unibody mounting points
- All mounting hardware included — straightforward bolt-on install
The frame braces are the standout feature. XJ Cherokees are unibody vehicles, and the factory bumper mounts are thin and lack structural support. Aftermarket bumpers that only bolt to those three factory mounting points on each side can feel flimsy, especially under recovery loads or hi-lift jack use. Dirtbound’s frame braces add three additional bolts per side along the frame rail, significantly stiffening the front end.
Sandblasting the Bumper and Brackets
Before any coating goes on, every piece gets a full media blast in Core 4x4’s blast room. Sandblasting removes mill scale, oils, and surface contaminants to give the powder coat a clean, etched surface to bond to. Both the bumper body and the frame brace brackets go through this step.
Prep is everything: Spence emphasizes that surface preparation is the most important step when coating steel. Even if you are working in your driveway with rattle cans, clean the steel with acetone or a degreaser and scuff every surface you can reach. Good prep means a finish that lasts instead of peeling after the first trail run.
Powder Coating: Primer, Top Coat, and UV Protection
Core 4x4 does all powder coating in-house. The process for the bumper and brackets:
- Primer coat — base layer for adhesion and corrosion resistance
- Orange top coat — applied with an electrostatic gun, then cured in the oven
- Clear coat — UV-stable layer to protect against sun fading
The finished orange powder coat is significantly more durable than spray paint. Powder coat resists chipping, scratching, and UV fading — all things a front bumper deals with on every trail run and every day sitting in the sun.
What If You Do Not Have a Powder Coat Setup?
Most people do not have a blast room and powder coating oven in their garage. Spence acknowledges this and offers practical advice:
- Rattle can or spray paint — works for a budget build, but prep work is critical. Clean, scuff, and use a UV-stable paint
- Clear coat over your color — adds UV protection and makes the finish last significantly longer
- Local powder coat shop — most areas have a shop that will coat parts for you at a reasonable price
- Bed liner — an alternative if you want maximum durability and do not care about color matching
Installing the Frame Braces
With the powder coating cured, installation starts with the frame braces. This is the more involved part of the install, particularly on the driver side.
Driver Side: Steering Box Removal
The driver-side frame brace shares mounting points with the steering box. You need to remove the last bolt holding the steering box on so the brace can slide into position. Dirtbound includes three new bolts — longer than the factory ones — that pass through both the frame brace and the steering box mount. This means the steering box ends up with stronger, longer hardware once the brace is installed.
Before bolting anything up, Spence blew out the bolt holes with compressed air and sprayed penetrating fluid into them. Years of road grime and rust accumulate inside these holes, and cleaning them now prevents seized hardware later.
Passenger Side
The passenger side is more straightforward since there is no steering box to work around. The brace bolts to the frame rail in the same fashion. On this particular XJ, the back bolt holes had a slight lip from previous modifications, so Spence drilled them out quickly to get the bolts to pass through cleanly.
Why Six Bolts Per Side Matters
Once both frame braces are installed and the bumper is mounted, each side has six bolts securing everything to the frame — the three original bumper mount bolts plus three additional frame brace bolts. This spreads the load across a much larger area of the unibody structure. Spence noted that he has always been nervous about aftermarket XJ bumpers that only attach to the three factory mounting points. The Dirtbound brace system eliminates that concern.
Mounting the Bumper
With both frame braces snugged into position, the bumper goes on. The process:
- Offer the bumper up and start all bolts finger-tight on both sides
- Check alignment — make sure the bumper is centered with the body lines before tightening
- Adjust if needed — on this XJ, it lined up well on the first try
- Torque all bolts — frame braces first, then bumper mounting bolts
Spence recommends snugging everything on one side, getting the other side to the same point, then doing a full mockup before final tightening. This way you can shift things around if alignment is off.
The Finished Result
The orange Dirtbound front bumper transforms the look of the XJ. The tube design keeps the profile clean without adding unnecessary bulk, and the stinger hoop gives it a trail-ready stance. Combined with the Rhino-lined body, 35-inch tires, and 4-inch lift, the Cherokee is finally starting to look like the build Spence envisioned.
More importantly, the frame braces make the front end feel solid. Spence climbed on the bumper to test — no flex, no movement. That is the kind of confidence you need when using a hi-lift jack or running a recovery strap through the bumper on the trail.
Tools and Parts Required
- Socket set and wrenches (metric and standard)
- Compressed air for cleaning out bolt holes
- Penetrating fluid for seized factory bolts
- Drill and drill bit (if bolt holes need to be opened up)
- Sandblasting equipment or sandpaper and degreaser for prep
- Paint, powder coat, or bed liner for finishing
What Is Next for the XJ Build
The front bumper is done. Next on the list: the rear bumper — another Dirtbound product that will get the same orange powder coat treatment. After that, Spence has his eye on orange wheels to complete the color theme. The XJ Cherokee build series continues.
