BushwackerCutout Pocket/Rivet Style Front & Rear Fender Flares | 4-Piece Set, Black, Smooth Finish | 40951-02 | Fits 2007-2013 GMC Sierra 1500 w/ 5.8' Bed

10 things I wished I knew before ordering the cut-out flares:1. The flares feel flimsy and cheap prior to mounting but really become a rigid and sturdy part of the truck once installed.2. The bolts are just for looks. The flares actually attach with small body screws under the fenderwell.3. The front fender flare gives you 1.5" of added clearance at the bottom of the rear of the front fender well.4. The 1.5 inches is the only added clearance. There is no benefit at the front of the front well or at all in the rear wells.5. The install is time consuming but not tricky or difficult as long as you closely follow the instructions.6. Cutting into your pickup's shiny painted body panels is a bit nerve racking. Once you start, there is no turning back.7. Use a thin cutting wheel.8. There are NO unnecessary steps in the instructions. Follow each step EXACTLY. Or you will regret it later.9. They almost cover a 35x12.50 but you still sling a little bit of mud onto the body.10. They are well worth the money, look great, add a little bit of clearance and will be on all my future 4x4s.
