K4148DL

Overview:

The Fabtech 5in Crawler Coilover system is engineered to deliver exceptional offroad articulation combined with refined highway performance for Jeep Wrangler JL owners. Designed specifically for 2018 to 2020 Jeep Wrangler Unlimited Rubicon, Sahara, Sport, and Sport S 6-cylinder 4-door models, this coilover conversion kit offers a robust and reliable suspension upgrade without the need for ongoing fabrication or maintenance. It provides superior damping and ride quality compared to traditional coil spring and shock setups, making it an ideal choice for drivers who demand both trail capability and daily drivability.

Fabtech’s system integrates Dirt Logic 2.5 coilover reservoirs in the front and Dirt Logic 2.25 shocks in the rear, delivering enhanced high-speed damping and improved ride comfort. The kit’s long arm design and precision-engineered link arm geometry ensure optimal handling, ground clearance, and articulation for serious offroad enthusiasts.

Key Features:

• 5-inch lift height tailored for Jeep JL 6-cylinder 4-door models
• Front Dirt Logic 2.5 coilover reservoirs with stainless steel construction for durability and superior damping
• Rear Dirt Logic 2.25 shocks optimized for offroad and highway performance
• Massive 2-inch OD, .313 wall thickness lower link arms built to resist bending under extreme conditions
• Fabtech’s legendary 5 Ton joints with lifetime guarantee for smooth, quiet operation and unmatched offroad durability
• Full-width front crossmember for precise link arm geometry and added frame strength
• Rear link arms mounted to new frame mounts for increased ground clearance and improved approach angles
• Designed to accommodate tire sizes up to 40x12.5R20 with appropriate fender modifications
• Optimized for use with standard or high clearance fenders, with minor trimming or cutting as required

Construction & Design:

Fabtech’s 5in Crawler Coilover system is built with high-quality materials and precision engineering to withstand the rigors of offroad driving. The lower link arms are constructed from heavy-duty 2-inch outer diameter tubing with .313-inch thick walls, ensuring exceptional strength and resistance to bending or deformation. The front crossmember spans the full width of the frame rails, reinforcing the lighter JL frame and maintaining proper suspension geometry under load.

The Dirt Logic coilovers feature stainless steel reservoirs that improve heat dissipation and shock performance during extended offroad use. Fabtech’s 5 Ton joints are engineered for longevity and smooth articulation, providing quiet street operation without sacrificing offroad toughness.

Installation & Fitment:

Installation of the Fabtech 5in Crawler Coilovers requires welding and is designed specifically for 2018 to 2020 Jeep Wrangler Unlimited Rubicon, Sahara, Sport, and Sport S models equipped with 6-cylinder engines and 4-door configurations. Exhaust modifications are necessary, or alternatively, the AFE P/N 48-48024 loop delete pipe can be ordered to accommodate the new suspension setup. Additionally, upgraded driveshafts (FTS94057 front and FTS94065 rear) are required for 4-door models to ensure proper driveline angles and reliability.

Minor trimming or cutting of fenders may be needed depending on tire and wheel size, especially when running larger 40-inch tires with high clearance fenders. This system is engineered to work seamlessly with standard fenders and tire sizes up to 37x12.5R20 with minimal trimming.
