Installing Tonnomaster fender flares is a practical way to upgrade your truck’s appearance, improve tire coverage, and help protect your vehicle from mud, rocks, and road debris.
Whether you drive daily, tow on weekends, or run wider tires, the key to a clean installation is simple: choose fender flares designed to match your exact truck and take your time during alignment.
What to Check Before Installing Fender Flares
Before starting, confirm:
-
Your truck’s year, make, model, trim, and body style
-
Whether the flares are OE style, pocket style, or rugged style
-
Tire clearance, especially with wider wheels or lift kits
-
Whether the kit uses factory mounting points or requires drilling
-
That each flare lines up properly with the wheel arch
Vehicle-specific Tonnomaster fender flares are designed for better fitment, cleaner body lines, and easier installation compared with universal options.
Tools You May Need
Most installations require basic tools:
-
Socket set and ratchet
-
Screwdrivers
-
Trim removal tool
-
Cleaning cloth and alcohol wipes
-
Gloves
-
Masking tape for alignment
Clean surfaces and proper tools help prevent poor fitment, loose hardware, and uneven gaps.
Step-by-Step Fender Flare Installation
1. Check the Kit
Separate the front and rear flares. Hold each piece against the wheel arch to confirm the shape and fit.
2. Clean the Wheel Arch
Remove dirt, wax, mud, and debris from the mounting area. A clean surface helps the flare sit properly.
3. Remove or Loosen Factory Fasteners
Some Tonnomaster fender flares use existing factory holes, while others may require supplied hardware.
4. Test-Fit Before Tightening
Hold the flare in place and check alignment, tire clearance, and door clearance before securing anything.
5. Secure the Flare
Install the hardware gradually. Tighten evenly and avoid over-tightening, especially with ABS plastic.
6. Repeat on Each Side
Compare both sides to make sure the gaps, height, and positioning are even.
7. Final Check
After installation, take a short drive and recheck the fasteners. Look for movement, rubbing, or uneven edges.
Do Fender Flares Require Drilling?
Not always. Many modern fender flare kits use factory mounting points, but some vehicles or flare styles may require drilling.
Always check the instructions before installation. Even “no-drill” kits still require careful alignment and proper fastening.
OE Style vs Pocket Style Fender Flares
OE style fender flares offer a clean, factory-like appearance and are usually easier to install.
Pocket style fender flares create a bolder, off-road look and work well with lifted trucks or wider tires, but they require more careful alignment.
For a subtle everyday upgrade, OE style is usually the easier choice. For a more aggressive truck build, pocket style may be the better fit.
Common Installation Mistakes to Avoid
Avoid these mistakes:
-
Choosing style before checking fitment
-
Skipping the dry-fit step
-
Over-tightening screws
-
Ignoring tire clearance
-
Installing over dirty surfaces
-
Assuming every kit is no-drill
-
Rushing alignment
Most installation problems come from poor preparation, not the fender flares themselves.
DIY or Professional Installation?
You can install Tonnomaster fender flares yourself if you are comfortable with basic tools and can follow instructions carefully.
Professional installation may be better if your truck is lifted, has oversized tires, requires drilling, or if you want a factory-level finish.
