Construction & Design:
Fabtech’s Crawler Coilover system is engineered with high-quality materials and precision manufacturing to withstand the rigors of offroad use. The lower link arms are constructed from thick-walled steel tubing, ensuring strength and resistance to bending or damage. The stainless steel Dirt Logic coilover reservoirs improve shock cooling and maintain consistent damping performance during extended trail use. The full-width front crossmember not only secures the link arms at the ideal geometry but also reinforces the JL frame, which is known for its lighter weight construction. This thoughtful design enhances durability without adding unnecessary weight.
Each component is designed to provide a perfect balance of strength, flexibility, and longevity, making the system reliable for both trail adventures and daily driving.
Installation & Fitment:
Installation of the Fabtech Crawler Coilovers requires welding and some modifications, including exhaust adjustments or the option to order an AFE loop delete pipe (P/N 48-48024). Driveshaft replacements are necessary for 4-door models (front FTS94057, rear FTS94065). This kit fits only 6-cylinder, 4-door Jeep Wrangler Unlimited models from 2018 through 2020. Minor trimming or cutting of fenders may be required depending on tire and wheel size as well as fender type (standard or high clearance).
Fabtech’s engineering ensures the system is ready to perform immediately after installation, eliminating the need for ongoing fabrication or maintenance.
