K4077DL

Overview:

The Fabtech 2.5 DLSS Crawler Coilover system is a comprehensive suspension upgrade designed specifically for Jeep Wrangler JK models from 2007 to 2018. Engineered for serious off-road enthusiasts, this heavy-duty coilover kit replaces all eight link arms with extended length units to deliver aggressive off-road capability while maintaining superior on-road driving characteristics. Featuring high-mounted links for maximum ground clearance and advanced coilover technology, this system balances rock crawling articulation with smooth highway performance.

Ideal for Jeep owners seeking enhanced suspension travel, durability, and ride quality, the Fabtech DLSS Crawler Coilovers provide a robust solution for tackling challenging terrain without sacrificing everyday drivability.

Key Features:

This coilover system integrates advanced components and thoughtful engineering to optimize both off-road and on-road performance:

• Extended length heavy-duty link arms replace all eight factory links for improved articulation and durability
• High-mounted link placement on the frame maximizes ground clearance to avoid obstacles
• Fabtech 5 Ton Joints ensure reliable, quiet operation backed by a lifetime warranty
• 1/4" thick steel weld-on Track Bar brackets relocate front and rear track bars for proper roll center alignment
• Bolt-on front Dirt Logic 2.5 coilover conversion offers outstanding high-speed damping and low-speed crawl control
• Coilovers mounted on axle centerline reduce premature link arm bushing wear and improve handling
• Dual rate coil springs maintain factory load carrying capacity with a smooth, compliant ride
• Flexible coil design provides extended travel for aggressive rock crawling and excellent highway manners
• Includes premium front and rear shocks with remote reservoirs for enhanced heat dissipation and consistent performance

Construction & Design:

Fabtech’s DLSS Crawler Coilover system is built with durability and performance in mind. The extended link arms are constructed from heavy-duty steel and utilize Fabtech’s proprietary 5 Ton Joints, designed to withstand the rigors of extreme off-road use while delivering a quiet, smooth ride. The weld-on track bar brackets are fabricated from 1/4" thick steel, providing the strongest and most reliable method to relocate track bars and maintain proper suspension geometry under heavy articulation.

The coilovers feature a dual rate spring design that balances factory load capacity with enhanced suspension travel. Mounted directly on the axle centerline, the coilovers reduce stress on link arm bushings, extending component life and improving vehicle handling. Remote reservoirs on the Dirt Logic shocks increase fluid capacity and cooling, ensuring consistent damping performance during extended off-road sessions.

Installation & Fitment:

Installation of the Fabtech DLSS Crawler Coilover system requires welding for the track bar brackets and some suspension components, making professional installation recommended for best results. Additionally, exhaust modifications are necessary on 2012–2018 Jeep Wrangler models, requiring the Fabtech loop delete pipe (FTS94060). For 2-door models, upgraded driveshafts are required for both front and rear applications depending on the model year.

This kit is designed to fit Jeep Wrangler JK models from 2007 through 2018, including Rubicon, Sahara, Sport, Sport S, Unlimited, and special anniversary editions. It supports large tire sizes up to 40/13.50R17 with appropriate wheel offsets and may require minor trimming or tube fenders depending on tire and wheel combinations.
