Fender Flair paint damage with flaps

[bigdave18629]

So I am confused. I was running husky mud flaps, took off my running boards and swapped them for power boards. After a recent trip to the sierras, my rear flairs are dammaged from road spray or something. The front edges of the rear flairs, and directly behind the mud flap on the rear of the flair. I mean like nearly touching the backside of the flairs. I thought that maybe the front tires some how shot all the way back to the front of the rear flairs, but that would mean it shot past the flaps, didn't touch the door or rockers and then kicked up to hit the flair. While it doesn't make sense, I guess weirder things happen. But for there to be dammage on the rear flair directly behind the flaps should be impossible. Again nothing on fenders or rockers. This is my 3rd raptor, all have had the same flairs added and I have never seen anything, let alone dammage. I was going 80 in the rain for a while. Just changes to rockblokz to stop it from happening again. I am just really frustrated with what looks like sand blasted flairs with no concept of how it happened, any thoughts?

The rear front damage is directly caused by your removal of the running boards. The rear of the rears is caused by wheel spray.

Are you running aftermarket wheels?

Running stock wheels, it is a 37 package. I get what you say about no running boards, but there was no damage at all the length of the truck, and the damage on the rear flair was low. That is a long way to travel with no other damage, and does not explain damage immediately behind the flap on the rear. As mentioned, same set up on 3 raptors and a couple platinum over the years and have never seen this. Almost like I created a vortex around the rear wheels

Can you post a pic? I would learn towards airflow at this point.

Platinum isn't apple to apples since they don't have the raptor wide front and rear fenders and flairs. Did you have 37's on your other raptors?

I will try to post some pics, no on the 37's. Stock 35's on gen 1 and gen 2. Both platinum trucks got a lift and 35's. Stock 37's on my gen 3. With hardly any spray on the doors, and the damage immediately behind the rear flair is what's confusing me. Also all trucks had the same flaps installed. The new rokblokz xl were just installed as a precaution.

More, pretty deep pits. Use it as a truck, no damage from some decent wheeling, but this from I 80

IMHO....
the front of the rears are 100% from the front wheels.
The rear of the rear looks like something rubbed against it. You can see the same damage on the mudflap. That's not road related. That looks like a human created issue.

 

[bigdave18629]

Appreciate you taking the time to look. Behind the flap isn't human related, hard to take a pic the truly shows it. The mud flap is the new one and there is no damage. It may be from the front tires but I have a hard time believing it based on past trucks with this set up and nothing at all on the body. Might be, but doesn't make sense.

It might be the angle but this looks like damage on the flap and it lines up with the fender.
