About This GMC Sierra Build
We love featuring real builds from real owners. This Grey GMC Sierra sits on a set of 24×12-inch Hartes Metal Whipsaw wheels, and the result speaks for itself.
The owner chose Hartes Metal for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of GMC Sierra builds come through WheelFront every month, but this one stands out. The combination of the Grey exterior with the Hartes Metal Whipsaw creates a look that balances aggression with elegance.
Fitment Breakdown: Hartes Metal Whipsaw on the GMC Sierra
I saw this GMC Sierra sitting in the lot, and the stance immediately caught my eye. The 24x12 Hartes Metal Whipsaw wheels fill the wheel wells perfectly. That massive width gives the truck a wide, planted look that stock wheels just cannot touch.
Running a 24-inch wheel on a 7-inch lift is a balancing act. We have to watch the offset closely to keep the tires from chewing up the inner liners. These wheels push the footprint out far enough to make the truck look aggressive without ruining the steering geometry.
The caliper clearance on this build is spot on. Hartes designed the Whipsaw spokes with enough arch to clear the Sierra’s front brakes easily. You do not have to worry about running thin spacers here.
We measured the hub bore, and it fits the Sierra’s hub perfectly. A tight hub-centric fit is essential for avoiding vibrations at highway speeds. Trust me, you do not want an annoying shimmy in the steering wheel.
The barrel lip depth on these 12-inch wide wheels creates an incredible sense of scale. It gives the truck a deep, custom aesthetic that draws the eye toward the center cap. The milling detail really pops against that deep black powder coat.
You will deal with a bit of potential rubbing on the back of the front fender liner. That is the price you pay for running a 35x13.50 tire on a 12-wide rim. A little trimming of the plastic liner solves the problem, but do not ignore it.
The 7-inch lift kit provides the necessary travel to keep those huge tires from hitting the metal crash bars. It is a tight fit, but it works. The whole setup screams custom work done the right way.
What We Recommend for GMC Sierra Owners
If you want this look, stick to a 12-wide wheel if you enjoy the deep dish aesthetic. Anything narrower and you lose that "wide-body" presence. Just make sure you pair it with a lift kit that actually clears the tire size.
We always suggest a negative offset for these Sierras. A -44 offset is usually the sweet spot for a 12-wide wheel. It pushes the tire out just past the fender flare for that perfect aggressive poke.
Do not even think about a staggered setup on a truck like this. Stick to a square configuration so you can rotate your tires properly. It saves you money and keeps the suspension wear even across all four corners.
Watch your tire stretch when running 13.50-inch wide tires on a 12-wide wheel. It is a slight stretch, but it looks purposeful and protects the rim edge from light curb contact. Do not go any narrower on the wheel if you want that meaty tire profile.
Avoid cheap spacers if you can. If your offset is correct, you should never need them. Quality wheels like these Hartes are engineered to bolt directly to your hub for maximum safety.
Style and Build Analysis
The Gloss Black and Milled finish is the highlight of this build. It creates a high-contrast look that bridges the gap between rugged utility and luxury custom. The grey paint on the Sierra provides a neutral, sophisticated backdrop for all that flash.
I love how the milled edges trace the spokes. It breaks up the dark void of the black finish and draws attention to the Whipsaw’s unique geometry. When the truck rolls, those milled lines catch the sun beautifully.
The proportions here are dialed in. Many builders go too small on the tires, but those 35-inch Amp Terrain Attack MTs fill the space perfectly. It looks like a truck that belongs on a show floor but could still crush a muddy trail.
Compared to the cookie-cutter builds we see at shows, this one stands out. It feels intentional rather than slapped together. Every choice, from the lift height to the tire tread pattern, serves a specific visual purpose.
The stance gives the truck a sense of authority. It sits high, wide, and looks like it owns the asphalt. This is how you modify a modern Sierra without losing its OEM soul.
Why We Love This Build
I spent twenty minutes just circling this truck at the meet. The way the grey paint shifts under the sun against those deep black wheels is mesmerizing. It strikes that rare balance of aggressive off-road capability and refined street style.
When the light hits the milled sections of the Hartes Whipsaws, the whole truck seems to glow. It commands attention without being obnoxious or overdone. Seeing it roll down the street makes you realize why we obsess over wheel fitment in the first place.
This build represents the gold standard for a lifted Sierra. It makes me want to run back to the garage and start my own project immediately. This truck is absolute perfection on four wheels.

Before You Buy: Fitment Checklist
We talk to GMC Sierra owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 24×12-inch wheels fit my GMC Sierra? Yes, but fitment depends on width, offset, and tire size working together. A wrong offset means rubbing. A wrong tire size means poor handling. Always verify all three.
Do I need to modify my fenders? That depends on your offset and suspension. A conservative offset with stock ride height usually fits without modification. Go aggressive and you may need to roll or pull your fenders.
Can I daily-drive this setup? Absolutely. Thousands of GMC Sierra owners run 24×12-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
