When you buy a brand-new truck like the GMC Sierra, it’s tempting to think the "Original Equipment Manufacturer" (OEM) accessories are the gold standard. After all, they were designed by the people who built the truck, right?
According to a recent viral review by Adventure Rocks, a veteran truck owner of two years, that assumption might be a costly mistake. In his detailed comparison, he reveals why he is finally ditching his GMC OEM liners for Lasfit GMC Floor Mats, and why you should consider doing the same from Day 1.

Quick Verdict: Real-World Testing Result
- OEM Floor Mats: Decent quality, but limited protection
- Lasfit Floor Mats: Designed for real-life mess, full coverage, better usability
👉 The biggest takeaway from the review:
Aftermarket mats like Lasfit outperform OEM in real-world conditions—especially in coverage and usability.
The Hidden Problem with OEM Mats: Coverage Gaps
“It’s not that these GMC OEM floor mats are awful… but there is one significant area where they fall short, and that is coverage.” — Adventure Rocks
After long-term use, the biggest issue becomes obvious:
❌ OEM Mats Leave Key Areas Exposed
- Door sill edges
- Under-seat carpet
- Center hump gaps
- Around the center console
Over time, these exposed zones become:
- Dirt traps
- Salt buildup areas (especially in winter)
- Permanent wear spots
👉 If you care about resale value, these gaps are a real liability.

Why Lasfit is the Superior Alternative
1. True Edge-to-Edge Protection
Unlike the factory options that stop short, Lasfit liners extend over the door sills. This ensures that when you’re hopping in with muddy boots, the dirt hits the TPE liner, not your truck’s carpet. From the dead pedal to the area behind the gas pedal, Lasfit covers the "blind spots" the manufacturers missed.
2. The "One-Piece" Advantage for Bench Seats
One of the most praised features in the review is Lasfit’s continuous front-row design. Many aftermarket brands (and even OEMs) use a "three-piece" system for trucks with bench seats. This creates seams where liquid and dirt can leak through. Lasfit provides one solid piece that flows over the center hump, ensuring nothing reaches the floorboards.
3. Precision Fit and Stability
Lasfit utilizes advanced 3D laser scanning technology. The result? A fit so tight it looks like it was molded into the vehicle. Plus, the liners utilize the factory retention clips, so there is zero sliding—guaranteeing safety under your pedals.
4. Raised Texture = Easier Cleaning
Compared to OEM:
- Higher raised patterns and channels
- Traps dirt, mud, and liquids more effectively
- Keeps debris contained in one area
Cleaning becomes simple:
- Shake it out
- Rinse with water
- Done
5. Better Value (Save $100+)
On average, Lasfit liners cost about $100 less than dealer-installed OEM packages—but the advantage goes beyond price. Instead of charging a premium for branding, Lasfit reinvests that cost difference into higher-quality TPE materials and better product engineering. The result is a liner that delivers more coverage, stronger performance, and longer-lasting protection—at a more reasonable price point.
Pro-Tips for a Perfect Installation
To get that "custom-molded" look seen in the video, follow these expert tips:
- The Warm-Up: TPE material has a "memory." When your mats arrive, take them out of the box and let them acclimate to room temperature (about 70°F) for a few hours. This allows any shipping creases to vanish.
- The Finishing Touch: For a 100% seamless fit, use a hair dryer or heat gun on a low setting to gently warm any edges that aren't laying perfectly flat. They will soften and mold perfectly to your truck's contours.
Final Thoughts: Which One Should You Choose?
If you’re only looking for basic, light-duty protection, OEM mats can get the job done.
But if you:
- Drive in mud, snow, or rain
- Have kids, pets, or outdoor gear
- Want to keep your GMC Sierra interior in top condition

They offer:
- Better coverage
- Better durability
- Better real-world performance
