Description

Overview

The Poison Spyder Rocker Knockers with Sliders, bare steel, part number 18-08-020, are body-mounted rocker guards with a tubular slider, written for the Jeep JK in 4-door models. They protect the rocker panel area while letting the Jeep slide over rocks and obstacles, and the body-mounted design is what sets them apart from the frame-mounted version.

Rocker panels are the most vulnerable part of a JK’s body, since they take hits from below and from the side on tight trails. These guards cover that area in 3/16 inch plate steel and add a slider that keeps the body sides away from taller rocks and trees.

Key features

  • Body-mounted to the tub at 14 strategic bolt locations
  • Mounting plate of 3/16 inch plate steel, precision brake-formed
  • Tubular rocker rail of 1.75 inch by .120 wall DOM tubing
  • Slider rail of CNC-bent 1.5 inch by .120 wall DOM tubing
  • Removable outer slider skid with oval dimples
  • Drain reliefs in the mounting plate to keep debris from collecting

Rocker protection on the trail

Rocker guards take contact on the sides of the body where rocks, stumps and tree trunks are common on tight trails. A body-mounted guard shares that load with the tub, while the slider keeps the Jeep moving over obstacles instead of catching them. Trail use puts repeated stress on the bolt points, so the guard should be checked as part of routine inspection.

Choosing between bare steel and a painted finish depends on how the Jeep will be used. Bare steel can be touched up with paint after welds or new scratches, and it can be coated later for more corrosion protection. Pair the guards with regular frame and mount checks, and plan the install around the cutting and drilling the kit requires.

  • Check bolts and nut plates after every few trail trips
  • Look for cracks at the bracket welds
  • Clear mud from the drain reliefs
  • Touch up bare steel to slow rust

Vehicle fitment

They fit the 4-door Jeep JK, the Wrangler from 2007 to 2018. Confirm your Jeep is a 4-door JK and check the body mounting points against your vehicle before ordering.

Confirm your vehicle’s year, model and trim before ordering.

Installation notes

Installation involves cutting or drilling, since the guards bolt to the body at key areas and the mounting plate is fitted to the tub. The guards work with any suspension, including long arm kits, and they lift with the body when a body lift is installed.

The skid attaches with countersunk stainless steel flat-head cap screws, so the outer surface stays flush when the screws are tightened.

Questions & Answers

Are the Rocker Knockers with Sliders 18-08-020 for a JK 4-door?

Yes. They are written for the Jeep JK in 4-door models. Confirm your Jeep is a 4-door JK from 2007 to 2018 before ordering, since the body mounts depend on the model.

Will they work with a body lift?

Yes. Because the rocker knockers mount directly to the body tub, they lift with the body when a body lift is installed. Frame-mounted guards can leave a gap in that case.

Can I replace the slider skid?

Yes. The outer skid is removable, so you can replace it if it is damaged or re-finish the slider to match your Jeep. The slider does not rely on the skid for structure.

Do the guards work with suspension lifts?

Yes. They are compatible with all known suspensions and body lifts, including long arm kits. They can also be used alongside JK Body Armor.

How do I maintain the slider skid?

Check it after each hard trail run for loose screws and dents. Tighten the countersunk stainless screws and replace the skid if it is badly bent, since a damaged skid can catch on rocks. Clean grit from the slider rail so it moves freely over obstacles.
