Front & back half kits FAQ
What changes with a front half versus a back half?
A front half replaces the forward frame rails and changes the space available for the front axle, steering and shocks. A back half replaces the rear rails. Choose it when you need room for rear coilovers, a different suspension layout or a wheelbase change. Each kit has its own mounting points and requirements.
Which YJ kit adds 15 inches, and what are the LJ options?
MB3067 extends the YJ rear frame by 15 inches. Compare it with the MB3001 YJ back half if a stretch is outside your plan. The 2004–2006 LJ kits have their own frame rails and come with a stubby rear bumper (MB3020-S) or a wide rear bumper (MB3020-W).
What else does the JT back half require?
MB3088 requires a Motobilt bobbed bed (MB1178 steel or MB1178-A aluminum), the MB5083 rear fuel cell, an AntiRock sway bar for the Gladiator with JK-length arms, and axles at least 68 inches wide. Review the full suspension and shock requirements on the kit page before ordering.
Who should install a frame half kit?
Replacing frame rails involves structural cutting and welding. Have an experienced chassis fabricator review the instructions for your kit and plan axle placement, steering or fuel-system clearance before the first cut.
