Product Details

This Trail system with Dirt Logic 2.5 coilovers provides enhanced suspension performance to address all variants of off highway travel use including rock crawling, aggressive trail use and overland expeditions. On road, the suspension has been tuned with proper rear dual rate coil springs and shock valving to provide a very compliant ride that you will appreciate.

The system is a complete short arm suspension that utilizes the factory control arm mounts for an easy installation. The Fabtech heavy duty link arms are constructed of 1.75&quot OD. .250″ thick wall steel tubing that are guaranteed never to bend. They come with large poly urethane bushings on one end with internal threads on the other to accept the ground breaking Fabtech 5 Ton Joint® for longevity and a quiet ride.

The coilover conversion includes heavy duty 1/4″ thick steel bracketry that attaches to the side of the Jeep coil spring bucket and to the frame for stout mounting of the Dirt Logic Coilovers. The Dirt Logic 2.5 Coilovers are the only all stainless steel body shock on the market. This is the most corrosive resistant shock there is. The ride quality of these Coilovers are vastly superior to a coil spring and shock configuration. This is the single biggest improvement you can do to your Jeep Gladiator to enhance the ride quality both on and offroad.

To address the steering geometry with the increased ride height, a Draglink Flip System along with a heavy duty Track Bar bracket is included. This relocates the steering geometry to the factory plane allowing for full articulation without binding the draglink ends in extreme conditions.

The factory angle of the draglink to the pitman arm does not change and there is no increased side load on the steering box sector shaft as compared to using a dropped pitman arm. This helps extends the life of the steering box with the increased ride height.

The heavy duty rear Track Bar bracket with side support maintains the factory roll center of the vehicle while centering the axle. Front and rear bumps stop extensions protect the suspension from over cycling.

Each Fabtech component has been designed with specific features and benefits that create this quality suspension system. For a greater understanding of each these components please see below.

This popular system is a top choice for daily drivers that enjoy tackling tough trails and overlanding with the comfort that they have a high quality complete suspension under their Jeep.

Features

  • Coilover Conversion: Bolt-on super stout bracketry allows the mounting of Dirt Logic 2.5 Coilovers for a superior highway ride while maintaining the ability to tackle the roughest off-road terrain.
  • Control Link Arms: Fabtech short arm link arms keep factory bushing cross-bolt angles parallel, eliminating premature bushing wear that can lead to poor handling.
  • Lower Link Arm Replacement: System replaces all four lower link arms due to their vulnerability to off-road obstacles and includes massive Fabtech 5 Ton Joints with a lifetime warranty.
  • Heavy-Duty Link Arm Construction: 1.75-inch OD link arms with .250-inch thick walls, guaranteed not to bend.
  • Dual Rate Long Travel Coil Springs: True dual-rate design allows the first stage to absorb small bumps for a compliant ride at lower speeds.
  • Progressive Spring Performance: As suspension travel increases, the spring rate increases to absorb larger impacts and support additional cargo.
  • Increased Suspension Travel: Coil springs provide excellent all-around driving performance while delivering increased suspension travel for off-road use.
  • Draglink Flip System: Heavy-duty draglink relocated on the steering knuckle retains factory steering geometry with the stock pitman arm, providing bind-free operation and eliminating bump steer.
  • Front Track Bar Bracket: 1/4-inch thick steel bolt-on bracket relocates the front track bar to the proper operating plane for long-term, trouble-free use.
  • Rear Track Bar Bracket: Bolt-on 1/4-inch thick steel bracket eliminates mount deflection and retains the factory roll center throughout suspension travel.
  • Bump Stop Extensions: Front and rear extensions prevent over-cycling with increased ride height and utilize factory closed-cell cushions for a progressive stop.
  • Sway Bar Links: Extended-length front and rear sway bar links with urethane bushings reposition the bars within factory operating planes and prevent binding at full extension.
  • Dirt Logic Shocks: Stainless steel shock bodies with NitroSteel piston rods provide maximum corrosion resistance, durability, and superior on-road and off-road damping performance.
