Product details

When stretching a Jeep YJ 15 inches to match an LJ-length wheelbase, the rear of the body and frame are moved back, but the center of the body remains factory length. This creates a mismatch between the front and rear sections of the Jeep.

The Motobilt 15 inch stretch rocker guards solve this by extending the rocker area to match the new body and frame length.

These rockers fill the gap created by the stretch and tie the front of the tub into the newly extended rear section. Without extending the rocker area, the body lines do not match, and the Jeep is left with exposed sections and reduced protection.

This design maintains a straight rocker profile while adding strength and protection along the side of the body. The rockers are built from formed plate and designed to handle trail abuse while supporting the overall structure of a stretched build.

These are intended to be used as part of a complete 15 inch stretch system, aligning with stretch corner armor, floor panels, and rear back half kits.

YJ to LJ Conversion System (Required Components)

To properly convert a Jeep YJ to LJ-length wheelbase, the following components are required:

Rear Back Half Kit (MB3067)
Stretch Corner Armor (MB1176, MB1170, MB1170-A, MB1175)
15 Inch Stretch Rocker Guards (MB1171, MB1171-A, MB1177, MB1177-S)
15 Inch Stretch Floor Panel (MB1172)
Inner Fenders (MB5529)
Drop Down Tailgate (MB1168)

These components work together to extend the chassis, body, and wheel opening location to properly match a 15 inch wheelbase stretch.

Frequently asked questions

Do I need stretch rocker guards when stretching a YJ?

Yes. When the rear of the Jeep is stretched, the rocker area must also be extended to match the new body length.

What happens if I do not run stretch rockers?

The body and frame will not align properly, leaving gaps and reducing protection along the side of the vehicle.

Are these required with MB3067?

For a complete and properly aligned build, yes. These are part of the full stretch system.

Additional product details & documents

The Motobilt Jeep YJ 15" Stretch Rocker Guards extend from the front fender all the way to the rear wheel well opening when stretching your Jeep YJ body by 15" in the rear. The rockers also include tie-in plates for the rear Stretch Corners which bolt to the rocker and the corner guards. We also include cap plates for both the front and rear of the rocker guards for added strength. We do not weld them in place as the installer may want to modify the rockers to better suit their build.

All parts are laser cut in-house and CNC-formed from 3/16 inch thick high-strength steel plate. Our rocker guards are formed so that they wrap underneath the body of your jeep and tie into the factory body mounts. Motobilt Jeep YJ 15" Stretch Rocker Guards are countersunk and ship bare metal with hardware included.

THESE ROCKER GUARDS ONLY WORK WITH THE 15” UNLIMITED BODY STRETCH.
