The Rokbloz are very well made and look great. I had them on my Tacoma. For my 4Runner I decided to try these short Ark rock flaps…it’s kept the rocks from flinging up…but my rock guards still get some mud splatter.
I bought OEM flaps and all four required drilling the body. 20" wheels on mine. Should have removed the wheels but by turning
the front wheel to the stops gave me enough room with a 90 degree chuck adapter.
On the rears I used a sharp drill bit (right angle drill adapter did not fit) by hand and worked it through the plastic.
I would rate the project 7 on a 10 PITA scale.
