Rear stretch coilover towers for the Jeep JK designed to support up to a 3.0 16 inch coilover while replacing the factory rear crossmember with a reinforced 3/16 inch structure built for link clearance and real suspension load.
When you stretch the rear of a JK, the factory structure runs out of room fast.
The MB1580 Rear Stretch Towers are built to give the suspension the space and strength it actually needs. Designed to support up to a 3.0 16 inch coilover, these towers allow proper shock placement without compromising link geometry or stuffing the shock into weak factory sheet metal.
The system replaces the factory rear suspension crossmember with a new 3/16 inch steel crossmember engineered with built in link clearance. This creates the room necessary for a rear 3 link suspension to cycle properly without fighting the chassis.
RockJock sway bar brackets are included and designed to relocate the sway bar to a new frame position that works with the stretched layout. The towers are designed to work with the MB5099 Micro Tomahawk Fuel Cell or a rear seat location fuel tank configuration, keeping the rear packaging clean and functional.
This is not a cosmetic upgrade. It is structural reconfiguration for builders who are serious about rear suspension performance.
