Best Chevy Colorado Running Boards & Nerf Bars: Power vs Fixed Step Guide

You swing open the door of your truck after ten hours on a job site. Your buddy stands there, one boot wedged on the rocker panel, hauling himself up by the grab handle. It works. Barely. A proper running board would've made that a clean one-step move. Whether the truck is a 2019 Z71 you've owned since new or a 2023 Trail Boss still smelling like the lot, the right step changes how you get in and out every single day. This guide breaks down power retractable steps versus fixed nerf bars so you stop second-guessing.

Quick Answer

Fixed nerf bars for the Chevy Colorado run $150 to $400 and bolt on in about an hour with basic hand tools. Power retractable steps cost $600 to $1,200, need a wiring harness tap, and take two to three hours to install. Both fit extended and crew cab models. For Z71 and Trail Boss trims that see real trail use, power steps win on ground clearance because they fold flush against the rocker when the door shuts.

Why Colorado Owners Add Running Boards in the First Place

The Colorado isn't a Silverado, but it isn't a Tacoma either. Stock ride height on a Z71 with the off-road suspension puts the rocker panel right around 22 inches off the ground. Add a 2-inch leveling kit and 33-inch tires, and now you're stepping up to a seat bottom that sits closer to your hip than your knee.

For a 6-foot guy with long legs, that's mild annoyance. For a shorter driver, a kid trying to climb in after soccer practice, or your father-in-law with a bad knee, it's a daily fight. I've watched a guy with a brand-new 2022 Z71 scratch his work pants on the rocker pinch weld every single morning before he gave up and put bars on.

There's a second reason that doesn't get talked about enough: rocker panel protection. The truck's lower body panel sits exposed to whatever the front tires kick up. Gravel, ice chunks, road salt, trail debris, it all hits that strip. A steel or aluminum step takes the abuse so the paint underneath doesn't. Owners running their trucks in Michigan winters or on Forest Service roads see this play out fast.

Running boards solve two problems at once: getting in cleaner and keeping the body cleaner.

Fixed Nerf Bars: What You Get for $150, $400

Fixed bars are the workhorse of this category. They've been on trucks since the '90s for a reason. They're cheap, bolt up fast, and don't break.

Tube vs Oval Bar Cross-Section

Round tube bars come in 3-inch and 4-inch diameters. The 3-inch tube looks proportional on the truck's body lines, especially the extended cab. A 4-inch tube starts to look chunky on a smaller truck like this, but it does give you more foot real estate if you wear size 13 work boots.

Oval bars are the other common shape. They sit a little wider and give you a flatter step surface than a round tube, which matters when it's raining or your boots are caked in mud. Most oval bars include a rubber tread strip down the top. The trade-off: oval bars hang lower than tube bars by about an inch in most designs.

Steel vs Aluminum Construction

Steel bars are heavier, usually 35 to 50 pounds for the pair, and almost always finished in black powder coat. They take a beating well as long as the coating stays intact. Once it chips, rust creeps in fast in salt country.

Aluminum bars run lighter, often under 25 pounds, and don't rust at all. They cost more, usually $50 to $100 above the steel equivalent. For a daily-driver truck in the salt belt, the math favors aluminum every time.

Install on either style is straightforward. Most kits use existing factory mounting holes underneath the rocker. Three bolts per side, torqued to spec. A floor jack, a 13mm and 15mm socket, and you're done before lunch.

Power Retractable Steps: What You Get for $600, $1,200

Power steps are the upgrade most owners don't think they need until they ride in a friend's truck with them. Then they want them.

How the Automatic Deploy Mechanism Works

A small electric motor sits inside each step assembly. When you open a door, a signal from the door-ajar circuit triggers the motor. The step swings down into position in about a second. Close the door, it folds back up flush against the rocker.

The good systems deploy off any door, including the rear doors on a crew cab. Cheaper ones only respond to the front doors. Check that spec before you buy.

Wiring and Install Complexity

This is where power steps get harder than fixed bars. The install kit includes a wiring harness that taps into the door-ajar circuit, usually at the body control module under the dash or via T-tap connectors at each door wiring bundle. You're routing wire from the step motors up through the rocker, into the cab, and to the BCM.

Most owners get it done in two to three hours with a basic socket set, a drill for a small access hole, and wire tap connectors. It's still DIY-friendly. Just budget a Saturday morning, not a coffee break.

The payoff is real. Retracted, the steps clear obstacles like fixed bars never can. The truck looks cleaner without bars hanging visibly below the doors. And the auto-deploy is genuinely useful when your hands are full.

Power vs Fixed: Side-by-Side Comparison by Key Factor

Here's the honest breakdown across the four factors that actually decide this purchase.

Factor	Fixed Nerf Bars	Power Retractable Steps
Price (pair, installed DIY)	$150–$400	$600–$1,200
Install time	~1 hour	2-3 hours
Ground clearance impact	Hangs 4-6 inches below rocker	Flush when retracted
Appearance when parked	Always visible	Tucked, clean lines
Failure points	None (passive)	Motor, sensor, wiring
Best for	Daily drivers, work trucks, budget builds	Off-road trims, lifted trucks, premium looks

Use this chart to match your driving pattern to the right step type.

The clearance number is the one that matters most for Z71 and Trail Boss owners. A fixed oval bar at the lowest point sits roughly 14 to 16 inches off the ground depending on tire size. On a moderately rocky trail, you will catch a bar. I've seen owners on Reddit post photos of bent oval bars after a single weekend in Moab.

Power steps, retracted, sit tight against the rocker at the same height as the body. They simply don't catch anything the truck wasn't already going to catch.

Fitment by Colorado Cab and Generation

The truck has gone through three distinct body styles. Bars are not cross-compatible across them.

First Gen (2004-2012) Fitment Notes

The original Colorado shared its platform with the Canyon. Bar kits from this era use bracket-style mounts that clamp to the frame rail, not the rocker. Extended cab bars run about 67 inches, crew cab around 77 inches. If you're restoring an early truck, here are the 2005 chevy colorado seat covers for the interior side of the project.

Second Gen (2015-2022) Fitment Notes

The redesigned 2015 model switched to body-mounted bracket systems with factory-drilled holes in the rocker frame. Most kits today list this generation as a single fitment because the rocker geometry stayed consistent through 2022. Crew cab bars are around 75 inches, extended cab closer to 65 inches. The Z71's optional rock rails use different mounting points than aftermarket nerf bars, so if your truck already has rails, plan on removing them first.

2023-2024 Colorado Fitment Notes

The 2023 redesign moved to the next-gen GMT 31XX platform with new body dimensions. Brackets from 2015-2022 bars do not fit. Always confirm year-specific fitment before ordering, and check the Chevrolet spec page if you need to verify cab length on a pre-owned build.

Off-Road Trims: Z71 and Trail Boss Clearance Considerations

If your truck spends weekends on actual trails, this section matters.

The Z71 and Trail Boss come with factory skid plates protecting the oil pan and transfer case. They also sit roughly an inch taller than a base WT trim from the suspension package. That extra inch helps, but it's not enough to make a low-hanging oval bar safe on rocky terrain.

Most owners running serious trails go one of two directions. Either power steps that fold flush, or high-clearance rock sliders that mount tight to the rocker and double as protection. Traditional nerf bars are the wrong answer if you're scrubbing the underside on granite.

If you split time between daily driving and occasional fire roads, a power step is the best compromise. Retract it when you turn off the pavement, and the truck has the same effective clearance as a stocker.

Protecting the Inside While You Upgrade the Outside

Adding a step means you'll use it. Muddy boots, wet jackets, and gravel-coated work pants are about to drag straight across your factory cloth seats every morning.

The stock fabric handles dirt about like a sponge handles water. Once it soaks in, it stays. I've seen 2018 work trucks with seat bottoms that look ten years older than the rest of the cab, all because of daily entry and exit with whatever's stuck to a pair of Red Wings.

This is where made-to-fit seat covers for the Chevrolet Colorado earn their keep. Tailored covers cut for the exact seat shape, airbag-safe, and they wipe clean with a damp rag. You can also browse best car seat covers if you're outfitting more than one truck in the driveway.

Install Tips That Save You a Saturday Afternoon

A few things I've learned watching guys do this in their driveways.

First, torque matters. Most bracket bolts spec out to 18 to 22 lb-ft. Crank them past that and you risk distorting the rocker pinch weld. The bars don't need to be cranked down like lug nuts. They need to be snug and locked with thread locker.

Second, check for factory mounting holes before you start drilling. Every 2015 and newer model has them pre-drilled from the factory under a plastic plug. Pop the plug, the threads are right there. Drilling new holes when you don't need to is the fastest way to ruin a job.

Third, on power step wiring, always disconnect the negative battery terminal first. The door-ajar circuit is live whenever the truck has power. One wrong tap will throw codes that take a scan tool to clear. Use proper T-tap connectors, not wire nuts and electrical tape.

Tools you'll want: a basic 3/8-inch socket set with metric sockets from 10mm to 17mm, a torque wrench, a cordless drill, T-tap connectors, and a floor jack with two stands. That's it.

Top Running Board Picks for the Chevy Colorado

Quick rundown of the directions most owners go, by use case.

For a budget fixed bar, a 3-inch black powder-coated steel tube bar in the $180 to $250 range covers it. Tyger and similar mid-tier brands have been on trucks for years without complaints. Easy install, durable enough, looks right on the truck.

For a power step upgrade, AMP Research PowerStep and similar systems run $1,000 to $1,200 for the application. Expensive, yes. Also the cleanest looking option on a Z71 or Trail Boss, and the only one that doesn't compromise clearance.

For off-road use, look at high-clearance aluminum nerf bars or full rock sliders. They mount tight to the rocker and sit only an inch or two below the body line, so they protect without catching.

Finish-wise, black powder coat is the default and looks correct on every trim. Polished stainless catches the eye but shows every scratch and scuff. Black anodized aluminum splits the difference, looks modern, fights salt corrosion, costs a bit more.

Frequently Asked Questions

Q: Do running boards fit all Chevy Colorado cab styles?

Fitment depends on cab configuration. Extended cab and crew cab bars are different lengths, usually about 65 inches versus 75 inches respectively on Gen 2 trucks. Bracket kits are also year-specific, especially across the Gen 1 (2004-2012) to Gen 2 (2015-2022) body change, and again at the 2023 redesign. Always order the bars listed for your exact year and cab style. Universal-fit bars exist but rarely sit right.

Q: Will nerf bars hurt ground clearance on a Z71 or Trail Boss?

Yes, fixed oval or tube bars reduce clearance and can catch rocks on technical trails. A typical oval bar hangs 4 to 6 inches below the rocker, putting the lowest point around 14 to 16 inches off the ground depending on tire size. Power retractable steps solve this by folding flush against the body when the door closes, keeping the underside clear. For dedicated trail trucks, this is the deciding factor.

Q: How long does it take to install running boards on a Colorado?

Fixed nerf bars take about an hour with basic hand tools, sometimes less if the factory mounting holes are clean. Power retractable steps take two to three hours because of the wiring harness tap into the door-ajar circuit. Plan a Saturday morning either way, since you'll spend the first 20 minutes unboxing, reading the directions, and getting tools laid out before you turn a single bolt.

Q: Are power running boards worth the extra cost on a Colorado?

If you prioritize off-road clearance and a clean look when parked, yes. The $600 to $1,200 premium gets you auto-deploy convenience and zero clearance penalty. If you mostly drive on pavement, haul work gear, and want a step that just works without electronics to fail, a quality fixed bar in the $150 to $400 range does the job for less. Match the spend to how you actually use the truck.

Q: Can I install Colorado running boards myself without a lift?

Yes. Most fixed bar kits use existing factory mounting holes or simple clamp brackets and go on with a floor jack and two jack stands. Power steps need a bit more access for routing the wiring harness, but they're still DIY-friendly with the truck on stands. A buddy holding one end of the bar while you start the bolts speeds things up considerably. No shop lift required.

Q: What finish holds up best in winter road salt conditions?

Aluminum with a black anodized finish resists salt corrosion better than anything else over a 5-year window. Black powder-coated steel holds up well too, as long as the coating stays intact. Once a chip exposes bare steel in salt country, rust spreads fast under the powder coat. Polished stainless is the most durable surface but shows scratches from any trail use. For Midwest and Northeast trucks, anodized aluminum wins.
