Product Details

This 5″ Trail system for the Jeep JL 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 JL suspension has been tuned with proper 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″ 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.

Fabtech’s long travel Dual Rate coil Springs are corner specific to the Jeep JL. This keeps the vehicle level side to side and allows for increased suspension travel. The first stage of the spring provides a soft ride with the ability to extend for additional travel. The second stage is designed to handle the payload of the vehicle and address large impact absorption at higher speeds.

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

  • Control Link Arms: Fabtech short arm link arms maintain proper factory bushing cross-bolt angles, eliminating premature bushing wear and ensuring proper 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: Corner-specific dual-rate coil springs provide a level side-to-side stance while maintaining factory load-carrying capacity and a smooth ride.
  • Progressive Spring Performance: True dual-rate design absorbs small bumps at low speeds while increasing spring rate under larger impacts and additional cargo loads.
  • Increased Suspension Travel: Coil springs are engineered for excellent all-around driving performance with added suspension travel for off-road use.
  • Draglink Flip System: Heavy-duty draglink relocation at 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 correct operating plane for long-term durability.
  • Rear Track Bar Bracket: Heavy-duty 1/4-inch thick bolt-on 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 while using factory closed-cell cushions for a progressive stop.
  • Sway Bar Links: Extended-length front and rear sway bar links with urethane bushings maintain proper operating angles and prevent binding at full suspension extension.
  • Parking Brake Bracket: Included extension bracket relocates the parking brake cable to prevent premature engagement caused by increased ride height and wheel travel.
  • Dirt Logic Shocks: Stainless steel shock bodies with NitroSteel piston rods provide superior corrosion resistance, durability, and excellent on-road and off-road damping performance.
