## Overview

The Poison Spyder 13-08-040 Rocker Knocker is a robust armor solution designed for Jeep YJ's and CJ-7's, featuring CNC laser-cut 3/16" plate steel for superior protection. Its precision brake-formed design ensures a perfect fit, while corrosion-resistant stainless hardware maintains a sleek appearance. This product is compatible with various aftermarket fenders, making it a versatile choice for off-road enthusiasts.

## Description

Poison Spyder Rocker Knockers are the ultimate protection for your Jeep's vulnerable rocker panel area. As the trails get tougher and recreational off-roading gets more and more hardcore, vehicle body damage becomes more prevalent. And rocker panels are most vulnerable, taking hits from both underneath and the sides as you work your way through tight obstacles. Poison Spyder Rocker Knockers protect your rocker panels by cladding them in rugged, high strength 3/16" plate steel armor. Rocker Knockers are manufactured to hug the lines of your Jeep's rocker panels perfectly, forming a glove-fit with virtually no loss of valuable ground clearance. Rocker Knockers are CNC laser cut from high strength 3/16" plate steel, and precision brake-formed for a perfect fit. Bolt holes are countersunk for the included stainless steel flat head hardware, which yields a flat, unobstructed surface to slide over obstacles. All mounting hardware is included as well as detailed installation instructions. Poison Spyder Rocker Knockers bolt to your Jeep's body in key areas, and interface with strengthened areas of the underside of the tub such as body mounts, strengthening ribs, etc. Because they mount to the body itself, there is no resulting gap or misalignment when a body lift is installed. This specific part number is for use on YJ's or CJ-7's that have been equipped with Poison Spyder DeFenders or Tube Fenders up front and the "Standard" or "Comp Cut" version of our Crusher Corners (they are not compatible with our "Stock" version YJ or CJ-7 Crusher Corners). For installations in which you would like to protect the paint underneath the Rocker Knocker, as well as provide a measure of vibration absorption, Poison Spyder offers Rubber Rocker Liners, precisely cut to fit between the Rocker Knocker and the Jeep's body (sold separately). This product ships as bare steel; it will need to be painted or powder coated prior to final installation.

## Features

- Fits YJ's & CJ-7's equipped with DeFenders and Crusher Corners, and many other manufacturers' replacment fenders and/or full corner guards
- CNC laser cut from 3/16" plate steel
- Precision brake-formed for a perfect fit
- Mounts to the Jeep's body to provide maximum armor protection with almost zero loss in ground clearance
- Flat-head stainless hardware looks great, is corrosion resistant, and won't hang up on rocks
