Technical Specifications and Features

The Fabtech suspension system is engineered with precision and durability in mind. It features heavy-duty 1/4-inch thick steel crossmembers, retaining factory alignment cam pins for easy adjustment. The triple front diff mounts reposition the differential for vibration-free operation at high speeds. The stainless steel Dirt Logic 2.5 Coilovers offer an outstanding ride quality both on and off-road, while the rear Dirt Logic 2.25 shocks aid in damping for a balanced ride. Rear lift is achieved by replacing the factory 2-inch block with a 5-inch block and u-bolt system, ensuring full suspension travel and lock-to-lock steering without over cycling.
  • Heavy Duty 1/4-inch Steel Crossmembers for added strength
  • Triple Front Diff Mounts for vibration-free operation
  • Stainless Steel Dirt Logic Coilovers for a balanced ride
