15 inch stretch aluminum boatside rocker armor for Jeep YJ adds major rocker clearance and includes cutting guides, closeout panels, and stretched corner tie-ins.

Assembly Instructions

The lower rocker panels on a Jeep YJ take abuse fast on the trail. Rocks, ledges, and tight obstacles tend to find sheet metal first, and the factory rocker area was never designed for serious rock crawling. Builders have been doing boatside conversions for years for one reason. More clearance and less body hanging on obstacles.

The simplest way to protect vulnerable factory rocker panels is to eliminate them. This 15-inch stretch aluminum boatside rocker armor kit replaces the lower rocker section with a high-clearance armor system that gains approximately 3-3/4 inches of vertical rocker clearance and roughly 3-3/8 inches of horizontal clearance per side. That extra clearance matters when sliding over rocks or working through technical terrain.

One of the biggest hurdles with a boatside conversion is knowing where to cut and how to get a clean, straight result. This kit includes a pair of steel cutting guides that remove the guesswork. Using the supplied guides and detailed instructions, builders can mark the cut lines accurately and complete the conversion with confidence. Interior floor closeout panels are also included to cover the trimmed area and help finish the interior, with the option to rivet or weld them in place.

The outer rocker armor is built from 3/16-inch high-quality aluminum and uses countersunk hardware for a smooth outer surface with no exposed bolt heads to hang on obstacles or take damage. End caps are included and can be welded on if desired. The kit also includes bolt plates designed to tie the stretched rocker armor into Motobilt stretched corner armor panels for added integration on larger builds.

Unlike frame-mounted rocker systems, this design stays independent of the frame and sits above the body mounts. That allows the system to work whether you run no body lift or different body lift heights without frame-mounted limitations.

For the 15-inch stretch aluminum boat sides, we highly recommend fabricating additional supports in front of the rear tire for extra support. On our builds, tubing tied from the roll cage into the rear inner fender has worked well and adds strength to the stretched rocker structure.

Built for serious fabrication and serious rock crawling, this system improves clearance, protects the body, and supports stretched YJ builds.

Frequently Asked Questions

How much clearance do these boatside rockers add?

This system adds approximately 3-3/4 inches of vertical rocker clearance and about 3-3/8 inches of horizontal clearance per side.

Does this kit include guides for cutting the body?

Yes. A pair of steel cutting guides is included to help mark accurate cut lines and remove guesswork during installation.

Do these rockers tie into the frame?

No. This system is independent of the frame, which allows compatibility with no body lift or varying body lift heights.

Will these boatside rockers fit a Jeep TJ or LJ?

No. These are designed specifically for the Jeep YJ and do not fit TJ or LJ models.

Will these work with factory parking brake cables?

The factory parking brake cable location interferes with the boatside conversion and must be relocated if retaining the factory parking brake.

Is additional support recommended for the 15-inch stretch version?

Yes. Additional fabricated support in front of the rear tire is strongly recommended for added strength on stretched applications.
