Fabtech Crawler Coilovers

2007–2018 Jeep Wrangler JK / Wrangler Unlimited

K4066DL

Overview:

The Fabtech 3-inch Crawler Coilover system is engineered specifically for Jeep Wrangler JK models from 2007 through 2018, including both two-door and four-door Unlimited variants. Designed for serious off-road enthusiasts, this heavy-duty coilover kit replaces all eight link arms with extended length units to provide exceptional articulation and ground clearance for aggressive rock crawling and trail driving. At the same time, it maintains superior on-road handling characteristics, delivering a smooth and controlled ride whether on pavement or rugged terrain.

This system is ideal for Jeep owners looking to upgrade their suspension for enhanced durability, articulation, and ride quality while running larger tires up to 37 inches with minor trimming or cutting as needed. Fabtech’s coilover design balances factory load carrying capacity with extended travel and high-speed damping, making it a versatile choice for both trail and highway use.

Key Features:

The Fabtech Crawler Coilovers combine advanced engineering and premium components to deliver reliable performance and durability:

• Extended length heavy-duty link arms replace all eight factory links for improved articulation and ground clearance
• Links mount high on the frame to maximize off-road clearance and reduce damage risk
• Fabtech 5 Ton Joints provide quiet, reliable pivot points backed by a lifetime warranty
• 1/4" thick steel weld-on Track Bar brackets relocate front and rear track bars for proper roll center and enhanced stability
• Bolt-on front Dirt Logic 2.5 coilover conversion offers outstanding high-speed damping and low-speed crawl capability
• Coilovers mounted on axle centerline to prevent premature link arm bushing wear and maintain precise handling
• Dual-rate coil springs maintain factory load capacity while providing a smooth ride and extended travel for rock crawling
• Rear Dirt Logic 2.25 shocks with reservoirs improve rear suspension performance and heat dissipation
• Compatible with tire sizes up to 37x12.50R20 with minor trimming or cutting depending on wheel offset and fender setup

Construction & Design:

Fabtech’s Crawler Coilover system is built with durability and performance in mind. The extended link arms are constructed from heavy-duty steel and utilize robust Fabtech 5 Ton Joints to ensure long-lasting reliability and quiet operation. The coilover shocks feature remote reservoirs that improve cooling and damping consistency during demanding off-road use. Dual-rate coil springs provide a balance of load carrying and articulation, allowing for smooth highway manners without sacrificing off-road capability.

Track Bar brackets are fabricated from 1/4-inch thick steel and designed to be welded on, providing the strongest possible mounting solution that prevents failure and maintains proper suspension geometry under extreme conditions. The coilover hoop kit and mounts are engineered for precise fitment and durability, ensuring the suspension components remain secure and functional through rigorous use.

Installation & Fitment:

Installation of the Fabtech Crawler Coilovers requires welding for the track bar brackets and some modifications to the exhaust system on 2012–2018 Jeep Wranglers, including the use of the Fabtech loop delete pipe (FTS94060). Additionally, driveshaft upgrades are necessary for four-door models, with specific front and rear driveshaft part numbers depending on the model year. Minor trimming or cutting of fenders may be required to accommodate larger tires, especially when running 37-inch sizes.

This kit fits a wide range of Jeep Wrangler JK models, including Rubicon, Sahara, Sport, Sport S, X, and special editions such as the 70th and 75th Anniversary models, covering model years 2007 through 2018.
