JLT Rock Blocker! (2015-2020 Shelby GT350/GT350R)

ROCK BLOCKER!!!! One of the very first things that was noticed after being around a few new GT350's was the rocks the side skirts collected under normal driving. We spent countless sleepless nights thinking of a solution for this MAJOR problem. After a Monday night of no sleep, we got it!

We designed these foam inserts that simply tuck into the open area of the side skirt to keep this area clean of road debris. These have been tested to 225 MPH on a stationary dyno :-D. We would recommend removing them for track days and extended high speed driving. They have been road tested to 100+ MPH, on a closed course. Do not attempt!

What's included: (2) JLT Rock blockers. Peace of mind and ability to sleep at night knowing rocks are not in your side skirts.

    I have used these for my GT500 and now have these for my GT350. They are great and do a wonderful job. If you don't have these you need to go ahead and buy it now.

    So happy that someone designed and produced this simple fix. I live down a long rock driveway and the rocks are always building up. Not anymore! Perfect fit and so easy to install.

    Although these are listed to fit 2015-2019 GT-350's they fit my 20 perfectly. The quality and fit are first rate and I believe they will work perfectly to keep stones from collecting on the side skirts. And the blend in great and no one will know that these were an added accessory. Well worth the investment and install in seconds!

    This is a must have if you daily drive. Keep the tiny rocks from laying on your rocker panel. If yor on race track then no. So the rockers can do the job they are meant to do!

    I got the JLT rock blocker the other day and they work great. I even took the car to high speeds today and they stayed in place. No more rocks!
