Key Features:

Fabtech’s Crawler Long Arm Suspension Kit incorporates advanced design elements and heavy-duty components to maximize performance and durability:

• 5-inch lift height optimized for 37-inch tires on standard fenders and up to 40-inch tires with high clearance fenders
• Front upper and lower link arms mounted to a full-width crossmember for precise geometry and added frame strength
• Massive 2-inch OD, .313 wall thickness lower link arms engineered to resist bending under extreme off-road conditions
• Fabtech’s legendary 5 Ton joints with lifetime warranty, providing smooth, quiet operation on and off-road
• Adjustable rear upper and lower link arms utilizing factory frame and axle brackets for straightforward installation
• Heavy-duty flipped draglink and front/rear track bar brackets for improved steering response and articulation
• Front and rear corner-specific dual rate coil springs for balanced ride quality and load handling
• Front and rear sway bar links and bump stop extensions to maintain suspension geometry and prevent damage
• DLSS reservoir shocks designed for enhanced damping and heat dissipation during demanding off-road use

Construction & Design:

Fabtech’s Crawler kit is constructed from premium materials to ensure long-lasting strength and reliability. The lower link arms are fabricated from thick-walled 2-inch diameter tubing, engineered to withstand the rigors of heavy off-road use without bending or fatigue. The full-width front crossmember not only secures the link arms in the ideal geometry but also reinforces the Gladiator’s frame rails, enhancing chassis rigidity under extreme conditions.

Each component is precision-engineered and powder-coated for corrosion resistance and durability. The use of Fabtech’s 5 Ton joints ensures superior articulation and longevity, backed by a lifetime warranty. This combination of robust materials and thoughtful engineering results in a suspension system that excels in both performance and durability.

Installation & Fitment:

This suspension kit is designed for 2020 Jeep Gladiator models equipped with the 3.6L V6 engine, including Launch Edition, Overland, Rubicon, and Sport trims. Installation requires welding and some exhaust modifications or the addition of an aftermarket loop delete pipe (aFe part #48-48024) to accommodate the lift. For heavy off-road use, upgraded driveshafts are recommended for 4-door models (front FTS94057, rear FTS94068).

Minor trimming or cutting of fenders may be necessary depending on tire and wheel size, especially when running larger 40-inch tires with high clearance fenders. Fabtech provides detailed instructions to guide professional or experienced installers through the process, ensuring proper fitment and optimal suspension geometry.
