Mid Frame Section for Jeep YJ / TJ / LJ

Looking to build out a complete Motobilt frame? The foundation starts with the Motobilt Mid Frame Section for the Jeep YJ, TJ, and LJ. Designed to work with the Motobilt front half and back half kits, this heavy-duty section provides the strength and precision fit needed to upgrade your rig’s foundation.

Fabricated from 3/16" thick American steel, the MB3080 is built to handle extreme off-road use and the rigors of trail abuse. Often when building a custom Jeep YJ, TJ, or LJ you find out that the center section is rusted out or damaged so what do you do? That’s where the mid frame section comes in as it’s a heavy duty center section designed to work with the Motobilt front and back half kits. Why buy a rusted out or expensive factory Jeep frame when you are building a hardcore off road rig? Many customers will use this frame section along with a back half kit to convert from a YJ or TJ to the LJ length or what’s referred to as an TJ-6.
