The CBI Offroad Covert front bumper has been on the Trailhunter for about a year now. It's been through snow, sand, rocks, and thousands of miles of highway. This is a real-world review — not a sponsored promo piece with perfect lighting and zero complaints. There are things I love about this bumper, and things that cost me real money and real frustration. I'm also announcing a new partnership with CBI. We're going to be working together going forward, and the deal is simple: I share real experiences with their products. The good and the bad. No filters. That's the only kind of content worth making, and it's the only kind of partnership worth having. The Bumper Itself Let's start with what CBI got right, because there's a lot. The Covert is a low-profile steel bumper that tucks up under the factory grille line. It doesn't scream aftermarket — it looks like it belongs on the truck. That was a big reason I went with it over some of the bulkier options on the market. From a distance, you almost don't notice it's not stock. Up close, you see the steel, the recovery points, the integrated winch mount, and you realize this thing means business. Build quality is solid. The welds are clean, the powder coat has held up through a year of trail abuse with no flaking or chipping, and the steel itself has taken hits without bending. I've dragged this thing over rocks at King of the Hammers, through tight lines in Sedona, and on every trail run in between. The bumper has done its job. It also maintains the factory sensors — parking sensors, front radar — which is critical on a daily-driven truck. That said, the sensor integration is where the story gets complicated. CBI's Install Video Before we get into the issues, it's worth noting that CBI doesn't include printed installation instructions with the Covert bumper. You get a QR code on the box that links to their YouTube playlist. Here's the official install video for the 4th gen Tacoma Covert: The video covers the basic bolt-up process and gives you a general idea of what to expect. What it doesn't cover — and what I wish someone had told me before the install — is the winch fitment and sensor wiring complications. That's what I'm going to walk through below. If you're planning this install yourself, I'd also recommend reading through this Tacoma4G forum thread where another owner documented their Super Stock Covert install with detailed photos of every step, including the front-end teardown, plastic cutting, winch mounting, and the fitment issues they encountered. It's the closest thing to a real install manual that exists for this bumper. Issue #1: Warn Zeon 10S Fitment and the Coolant Line CBI Covert winch tray. Image: CBI Offroad The CBI Covert is marketed as compatible with "most winches up to 10,000 lbs." I went with the Warn Zeon 10S — an industry-standard synthetic rope winch that should be a natural pairing. It fits. Barely. The Zeon 10S is a tight squeeze in the Covert's winch tray. The integrated solenoid on the Zeon 10S makes the winch body wider than a lot of other options, and in this bumper, every millimeter counts. To make it work, the sensor wiring had to be spliced to create enough clearance for the winch body. That splice was done by the shop that installed it — Doetsch Offroad in Chandler, Arizona — and it worked initially. The bigger problem was clearance between the winch and the coolant line. On the 4th gen Tacoma, the coolant hose runs right behind where a winch sits in the Covert's tray. The Zeon 10S sits close enough to the line that over time, vibration and trail impacts caused the winch body to rub against the coolant hose. I didn't catch it until I was dealing with a coolant leak. If you watch the CBI install video above, you can see how tight the space is behind the bumper. What the video doesn't show is what happens after thousands of miles of off-road use — the winch shifts, the hose flexes, and eventually they make contact. The Tacoma4G install thread has close-up photos of this exact area that are worth studying before you commit to a winch choice. The repair bill: $1,500. That's a coolant line replacement on a 2024 Tacoma with aftermarket armor in the way. Not fun. Doetsch Offroad did engage and helped get the coolant line fixed, which I appreciated. But they did not take any ownership of the install that caused the problem in the first place. I paid for the entire repair out of my own pocket — parts, labor, everything. When your install shop puts a winch in too tight and it wears through a coolant line, you'd expect them to stand behind the work. That didn't happen. This is a fitment issue that CBI and the aftermarket community are aware of. If you're running a Zeon 10S in a Covert bumper, check your coolant line clearance. If you're about to install, consider a winch with an external solenoid (like the Warn VR EVO or a Badland Apex) or a slightly smaller form factor. The Tacoma4G forum poster used a Badland winch with a separate solenoid box and it cleared with room to spare. The extra 30 minutes of research could save you $1,500. Issue #2: Rigid Fog Light Brackets If you're planning to run Rigid fog lights in the Covert — and most people are — know that the mounting brackets are not included with the bumper. They're a separate purchase, and they weren't available when I ordered. That set the install back several weeks while I waited for the brackets to ship. Not a huge deal in the grand scheme, but it's frustrating when you've got a bumper sitting in the shop and you can't finish the build because of a bracket. Worth knowing ahead of time so you can order the brackets with the bumper and avoid the delay. Issue #3: Sensor Wiring Splices and Intermittent Errors This one has been the most frustrating ongoing issue — and it's directly related to the winch fitment problem above. Because the sensor wiring was spliced during the winch install to create clearance for the Zeon 10S, the connections aren't as robust as factory. This is the part that CBI's install video doesn't address and that most people don't think about until it's too late. The 4th gen Tacoma's front parking sensors and radar are wired through a harness that runs right through the bumper area. When you install a Covert bumper with a winch, that harness has to be rerouted or modified to fit. With an integrated solenoid winch like the Zeon 10S, there isn't enough room — so the shop spliced the wires to shorten the harness. During heavy off-road use — sudden drops, hard landings, rough washboard — the spliced sensor connections lose contact intermittently. When that happens, the truck throws error codes that take over the entire infotainment display. We're talking full-screen error messages that override your navigation, your music, everything. When you're running a trail and relying on GPS, having your screen hijacked by a sensor error is more than annoying — it's a safety issue. The errors are intermittent, which makes them even worse. Sometimes they clear on their own. Sometimes they don't. Sometimes they come back five minutes later. I reached out to Doetsch Offroad multiple times since they did the original install. They didn't want to engage. No troubleshooting, no interest in diagnosing the spliced connection issue. I eventually took the truck to Toyota and paid $250 out of pocket for an hour of diagnostic labor. Toyota confirmed it was a wiring issue — not a sensor failure, not a module problem. A wiring issue from the install. The fix came from an unexpected place. A separate shop was installing a light bar on the truck and had to remove the front shroud. When they pulled it off, they noticed the wiring harness was being pulled tight — likely stressed by the way the shroud was seated over the spliced connections. When they reinstalled the shroud, the sensor errors stopped. It's been solid since. So the root cause was almost certainly loose or stressed wiring from the original bumper and winch install. A problem that Doetsch could have diagnosed and fixed if they'd been willing to look. Instead, I spent months chasing intermittent errors and paid Toyota to tell me what the install shop should have caught. Bottom line for anyone doing this install: do not let anyone splice your sensor wiring. If the winch doesn't fit without cutting wires, choose a different winch or wait for CBI's plug-and-play harness (more on that below). CBI Steps Up Here's where the story turns. I reached out to my contacts at CBI directly, and they didn't dodge it. They acknowledged the splicing issue and told me about a new product they'd been developing — a plug-and-play sensor harness that eliminates the need for any wire splicing. It connects directly to the factory harness with OEM-style connectors. They sent it over with a hand-signed letter from Nathan and the CBI/Prinsu team acknowledging the hassle and a discount code for future products. That's how you handle a product issue — you own it, you fix it, and you make it right. The install does require a new factory harness from Toyota (about $150), since the original was spliced. Once I get the factory harness, the new CBI connector mates directly — no cutting, no soldering, no hoping the splice holds through the next rock garden. This is the kind of thing that turns a frustrated customer into a long-term partner. CBI didn't pretend the problem didn't exist. They engineered a solution and shipped it to me before I had to ask twice. That matters more than any spec sheet. The Doetsch Offroad Experience I want to be transparent about this because other Tacoma owners in the East Valley will be looking for shops. Doetsch Offroad in Chandler, Arizona installed the bumper and winch. When the coolant line issue came up, they helped get it repaired — but I paid for the entire fix out of pocket despite the problem being caused by their install. When the sensor issues started, I reached out multiple times and was met with deflection. No troubleshooting, no follow-through. I ended up paying Toyota $250 for diagnostics and relying on a completely different shop to accidentally find the root cause while doing unrelated work. This is a pattern, not a one-off. Two separate issues caused by the same install, and both times I was left to diagnose and pay for the fixes myself. Doetsch is an install shop, not a fabricator — their entire value is the quality of the install and standing behind the work. When that doesn't happen, there's no reason to go back. I'm not here to trash anyone's business. But when something goes wrong with your install, the measure of a shop is how they handle it. In my case, I was on my own. That's a deal-breaker for a shop relationship. The Partnership Going Forward So why partner with CBI after all this? Because they handled it the right way. The bumper itself is a great product — well-designed, well-built, and it looks incredible on the truck. The issues I ran into were real, but they were fixable, and CBI was the one who fixed them. That tells me more about a company than a perfect product launch ever could. Going forward, I'll be sharing my experiences with CBI products on the Trailhunter build — install processes, trail performance, fitment notes, problems, and solutions. All of it. No PR filter. CBI is on board with that approach, which is exactly why the partnership works. If you're building a 4th gen Tacoma and considering the Covert bumper, here's my honest take after a year: What I love: Low-profile design that doesn't ruin the truck's lines Solid steel construction that's taken real hits Factory sensor retention Integrated winch mount and recovery points CBI's willingness to address issues head-on What to watch out for: Warn Zeon 10S fitment is extremely tight — check coolant line clearance Choose a winch with an external/relocatable solenoid to avoid the clearance nightmare Rigid fog light brackets are sold separately — order them with the bumper or you'll wait weeks Do not splice your sensor wiring — wait for the CBI plug-and-play harness connector Choose your install shop carefully — the shop matters as much as the product Watch CBI's install video and read the Tacoma4G install thread before you start — there's no printed manual The bumper stays on. The partnership is just getting started.

Does anyone else use Lasfit LED backlights? I've had mine for over 6 months now. They work perfectly. Honestly, sometimes I even forgot about them. That's the way it should be.

Just to share a tip for anyone who hasn't installed them yet on their truck. They only work when they are in the bulb sockets one way. So put the bulb in the socket and test them before placing the socket back into the light housing.

If they don't work, just pull the bulb out and switch them around. I hope this makes sense.
