5″ Crawler® System w/ Front Dirt Logic 2.5 Resi Coilovers & Rear Dirt Logic 2.25 Resi Shocks – K4149DL
2018-20 Jeep JL 4WD [4-DOOR]
Fabtech’s 5" Crawler® Coilover system provides unsurpassed articulation for offroad use with great highway manners for the daily driver. This Jeep JL Long Arm system is built to meet the most experienced driver‚Äôs expectations without having a questionably fabricated suspension. If you are in the market for a system that will work properly right out of the box and does not require continued fabrication and constant maintenance, look no further.
This Jeep JL Coilover Conversion provides superior offroad suspension damping with a great highway ride compared to a separate coil spring and shock configuration. The stainless steel Dirt Logic 2.5 Coilover offers a noticeable increase in ride quality and high speed damping that Jeep owners will appreciate.
A key part of the mounting of the Crawler’s 5 Ton Link Arms® to the frame is the geometry and ground clearance. The location of the frame side of the link arms is critical in providing superior handling throughout the travel range. Fabtech has found the sweet spot geometry for the link arms that provide a superior driving long arm system compared to all others on the market.
Front link arms are mounted to a full width crossmember that spans frame rail to frame rail. This crossmember is a key in not only in mounting the Links arms at the correct geometry but it adds critical strength to the lighter weight JL frame for hard offroad use. Rear links attach to new frame mounts on the side of the frame for increased ground clearance and approach angle.
The Fabtech lower Link Arms are massive and built of 2" OD .313 thick wall tubing that is guaranteed not to bend. Upper and lower Link Arms includes the Fabtech‚Äôs legendary 5 Ton joints® that come with lifetime guarantee of never wearing out. They are superior for offroad use with a smooth quiet operation on the street.

LINK ARM CROSSMEMBER & MOUNTS
A key part of the mounting of the long arm links to the frame is the geometry and ground clearance. The location of the frame side of the Link Arms is critical in providing superior handling throughout the travel range. Fabtech has found the sweet spot for the Link Arms that provide a superior driving Long Arm system compared to all others on the market.
Front Link Arm mounts are a full crossmember that spans frame rail to frame rail with no welding required for installation. This crossmember adds strength to the frame that is critical when running big tires with lots or articulation on a JL.
The rear frame mounts attach to the side of the frame increasing the approach angle of the lower links for increased clearance over large obstacles.
REAR DUAL RATE LONG TRAVEL COIL SPRINGS
Corner specific Dual Rate coils springs provide a level stance side to side and offer factory load carrying capacity with a smooth ride.
As a true dual rate coil, the first stage of the coil allows the spring to respond to small bumps for a very complaint ride at lower speeds. As the spring travels further, the rate increases to absorb larger impacts and support additional cargo of the vehicle.
These springs are the best on the market for all around driving while providing increased suspension travel for offroad use.
DRAGLINK FLIP SYSTEM
A heavy duty draglink is relocated on the steering knuckle to retain the factory steering geometry with the stock pitman arm. It provides bind free operation at full articulation and eliminates bump steer throughout the travel. It does not increase load on the steering box like a dropped pitman arm can.
FRONT TRACK BAR BRACKET
To work in conjunction with the Draglink Flip System, the front Track Bar is relocated to the proper operating plane with a 1/4" thick steel bracket that welds to the axle housing for a lifetime of trouble free use.
BUMP STOP EXTENSIONS
Front and rear bump stop extensions keep the suspension from over cycling with the increased ride height preventing damage to steering and suspension parts. The extensions utilize the factory closed cell cushions for a progressive stop at the end of the suspension travel.
BRAKE LINE DROPS
Factory brake lines are relocated down with simplistic brackets for the new range of travel to prevent tugging and interfere with suspension components. The brake system does not need to be opened for these drop brackets.
SWAY BAR LINKS
The extended length front and rear sway bar links with urethane bushings reposition the bars to work within the factory operating planes. These links are provided to eliminate the sway bar from going over center and creating link bind at full extension travel.
REAR TRACK BAR BRACKET
A weld on 1/4" thick steel bracket is built to eliminate mount deflection when the track bar moves through its full cycle. It relocates the factory track bar to retain the important factory roll center.
The bolt on front Dirt Logic 2.5 Coilover conversion provides outstanding high speed damping with the ability to crawl at low speed with maximum articulation for big rocks. Retains the factory coil spring bucket with minimal cutting for installation. The ultimate damping upgrade for rugged terrain with a great highway ride.
REAR DIRT LOGIC SHOCKS
Constructed of a stainless steel body with a NitroSteel® piston rod for maximum corrosion resistance and durability. Dirt Logic shocks have a superior ride quality both on and offroad with excellent damping for offroad use.
