Product Details
The dual-rate coil springs in this Fabtech 3-inch Sport System are designed with two stages to balance off-road capability and on-road comfort. The first stage offers a softer ride for extended suspension travel, while the second stage handles vehicle payload and absorbs impacts at higher speeds. These springs are corner-specific for the Jeep JL 4-door, ensuring the vehicle stays level side-to-side and maximizes suspension travel.
This system includes four bump stop extensions that work with your factory bump stops, providing compliant cushioning at full compression. They are designed to maintain the stock down travel, preventing over-cycling of the suspension and driveline. Extended front and rear sway bar links, equipped with urethane bushings, reposition the sway bars to operate within their factory planes. This extension prevents the sway bar from going over center, which can cause binding during full extension travel.
A heavy-duty rear track bar bracket is also included to re-center the axle. This bracket helps maintain the vehicle's factory roll center even with the increased ride height. The system comes with front and rear Stealth Monotube shocks, offering a robust solution for your lifted Jeep Wrangler.
