Unmatched Strength with J-Link Lower Control Arms
This system upgrades factory suspension geometry with front and rear fixed-length J-Link lower control arms, constructed from 2" x .250-wall DOM steel tubing. These arms increase durability and add front caster and rear wheelbase while maintaining OE-style rubber bushings for optimized NVH isolation.
High-Performance Coil Springs for All Terrains
Dual rate coil springs—available in standard or HD—deliver superior ride comfort and control. HD springs are perfect for rigs running a winch bumper, full-size spare, or roof rack, ensuring proper support under load without compromising articulation.
Shock Options for Custom Ride Feel
Choose between JSPEC gas shocks or FOX 2.5 Performance Elite Series with DSC (Dual Speed Compression) adjusters. Each shock is precision-valved to pair with this suspension system, offering improved control and compliance on road and trail.
Optimized Suspension Geometry
- Adjustable front track bar and rear track bar bracket maintain proper axle positioning
- Sway bar quicker disconnects improve off-road articulation
- Bump stop extensions included to protect against suspension over-travel
