JLT Rock Blockers (2020-2021 GT500)

ROCK BLOCKER!!!! One of the very first things that was noticed after being around a few new GT500'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 on your side skirts.

    Easy to install and they work as described. It's nice to not have small rocks/pebbles flying thru the opening. Thanks for this product. It works perfectly!

    I would have rated them five stars if they would fit more tightly. They seem to move around the space that they fit into so I have to use some glue to hold them in.

    This easy to install accessory really works. They are excellent keeping 100% of the debris from coming in on the running boards. Cheap, efficient, easy to install.

    Received the rock blockers this weekend. Fit and finish are really good. def recommend it. I also would suggest JLT to create some front mud flaps that would look and fit commensurate with cars line as an additional item to install.
