I am looking at WeatherTech mud flaps [ no drill with locking clip ] to put on in winter mainly to keep slush from building-up on my running boards. My question, when installed on a Super Duty are the flaps long enough to accomplish this? In the website illustration it appears to be close, does anybody with a stock f350 crewcab with snowplow package, black platform (factory installed) step boards and roughly 33.5" OD tires have this setup? Thank you.

 

Get the Duraflaps. Mine are great. They're long and wide enough to keep stuff from being kicked up. No holes to drill. They use the existing mounting points.

 

 

I leave my WeatherTech no-drill mudflaps on year-round, and there was no great accumulation of freezing slush on the running boards last winter.

 

I've got a 17 CCLB with stock 18" wheels with the stock AT tires with the Weathertech mudflaps front and rear. I put them on at Christmas in 17 and as such they have been on the truck for over a year. My truck doesn't see much off-road but saw plenty of snow/ice/rain over the past year. My truck has the extended running board option installed stock and I never saw a problem with buildup on the running boards. Maybe the front edge/corner a little bit but nothing I noticed or had to deal with. Had more problem with accumulation from normal snowfall on top of the boards making them slippery. The flaps to me do a perfectly adequate job keeping tire spray off the truck in road driving situations and they are very sturdy.

However, while there is no drilling/cutting involved in the install, I would not recommend installing/uninstalling every other season. The install reuses body pushpins and one small screw from the stock truck body on top of the locking clip on the mudflap. If you continually take on/off the flaps the pushpin tree will wear out and you will likely strip the little metal bracket that the small screw fastens into. This is all coming from memory from a year ago but I think the metal bracket was attached to the body in a way that would make it a pain to replace. Extra pushpins can be ordered off Amazon. If you're willing to potentially replace these elements then it should be feasible but I still wouldn't recommend.

 

I have lost some of my push pins.Whats size did you order from Amazon?
Thanks Mike

 

 

Honestly I don't think any mudflap that is very securely held on is going to be easy to change seasonally. The Durflaps were not difficult to install but there was definitely some finagling to get some of the holes to line up perfectly. I just leave em on all year round. Just give em a good hose down after the winter and you're good.
