## Overview

JLT Performance Rock Blockers are custom-designed foam inserts for 2015-2018 Mustang Shelby GT350 side skirts. Tested up to 225 MPH, they prevent rock and debris buildup with a simple peel & stick installation, offering lightweight, durable protection that keeps your vehicle looking sharp on every drive.

## Description

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

## Features

- Keeps the rocks off your GT350

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect.
*by R***R on November 17, 2019*

Seriously the best (and easily the least expensive) “upgrade” you can buy for your GT350. No more gravel accumulating on the rockers or flying through to scratch up your doors. It’s basically a foam plug you stuff in the gap. They come in a pair. Installation, if you can call it that, is maybe ten seconds. Problem solved. Brilliant.

### ⭐⭐⭐⭐⭐ Nice product that won’t damage your car or finish.
*by D***N on December 23, 2019*

Product works as described. Super easy to install/remove. Stays in place with track use and car washes.

### ⭐⭐⭐⭐⭐ Best Rock Protection !!
*by T***3 on December 26, 2019*

The Best Period !! Protect your Shelby from accumulating rocks in the rocker panel. This is one of the first things I did to my 2017 Shelby and since then I also purchased a back up pair. Great Idea and easy to plug in !!
