Poison Spyder Rocker Knockers

Poison Spyder Customs "Rocker Knockers" are engineered for the serious off-road enthusiast. This rocker panel protection is not the normal 10 gauge bolt-ons. This steel hits back!

Rocker Knockers don't just bolt to the Jeep body, but attach at the body mounts also. One of the best features of Poison Spyder Customs rocker protection is the ability to tie the front hoop of your cage directly to the rocker, giving your 4X a simple frame tie-in. Cage mounting holes are not pre-drilled, because cage mounting location will vary. Jeep TJs do not have this extension, due to preexisting body reinforcement.

Rocker Knockers can be used alone or in combination with Crusher Corners. The two armor pieces fit together at the rear flare. Used together they protect your Jeep body from the front wheel well to the tailgate. Rockers include counter sunk 3/8' stainless bolts. Rocker Knockers work with all known body lifts (though certain body lifts may require modification).

Prevent or repair trail damage. Rocker Knockers are constructed from 3/16" laser plate steel.

The Rockers protect without losing any ground clearance. In addition, they give you a solid Hi-Lift Jack location, and can be used as a pivot point.


Protect your off-highway machine without dramatically altering its appearance. Cosmetic diamond plate or heavy sheet metal won't prevent body damage when steel and rock collide on the trail.

Rockers can be ordered with an optional Slider Bar. Slider Bar provides a step and additional door protection. Slider bar is additional and must be requested upon order. Constructed from 1.5" .120 wall DOM tubing.

Poison Spyder now offers a light weight alternative for rocker protection for Jeep TJ's & YJ's. Rocker knockers constructed from aluminum are a minimal 12 lbs each, protects rockers and are strong enough to be used as a hi-lift jack point. Also made from 3/16" material with a horizontal brush finish gives a more brazen look for Jeeps not requiring the brute strength of steel. Aluminum Jeep rocker protection is not intended for the heavily used trail machine, as it will not hold up to continued abuse like it's laser plate steel counterpart. Aluminum Jeep rocker protection is not available with slider bar.

Also available from Poison Spyder are the Slider Liners

Poison Spyder's Slider Liners are a quick and easy solution to providing a thin cushion between your Jeep's body and aftermarket rocker protection. Slider Liners work with Rocker Knocker and Ricochet Rockers, incorporating a cutout that allows the body color to show through the Slider Liner and Rocker Panel. Sold in pairs.
