Overview:

The Fabtech 3-inch Gas Crawler Long Arm Suspension Kit with DLSS Reservoir is engineered specifically for the 2020 Jeep Gladiator 6-cylinder models. Designed to deliver exceptional off-road capability without compromising on-road comfort, this kit offers a robust and reliable upgrade for serious Jeep enthusiasts. Fabtech’s Crawler system is built to meet the demands of experienced off-road drivers who require a suspension that performs flawlessly right out of the box, eliminating the need for ongoing fabrication or maintenance.

With a focus on optimized link arm geometry and increased ground clearance, this long arm kit enhances handling and articulation across the entire suspension travel range. It is ideal for Gladiator owners seeking a durable, high-performance suspension that balances rugged off-road performance with smooth highway manners.

Key Features:

This Fabtech suspension system incorporates advanced engineering and premium components to ensure superior performance and durability:

• Precision-engineered front and rear upper and lower link arms with optimized geometry for improved handling and articulation
• Full-width front crossmember spanning frame rails for enhanced frame strength and proper link arm mounting
• Massive 2-inch OD, .313 wall thickness lower link arms designed to resist bending under extreme conditions
• Fabtech’s legendary 5 Ton joints with lifetime warranty, providing smooth, quiet operation on and off-road
• Heavy-duty flipped draglink for improved steering geometry and durability
• Front and rear track bar brackets for precise axle alignment
• Corner-specific dual rate coil springs front and rear for balanced ride quality and articulation
• Front and rear sway bar links and bump stop extensions to maintain suspension travel and control
• Front shock mount bracket engineered for optimal shock positioning

Construction & Design:

Fabtech’s Crawler long arm kit is constructed from high-strength materials designed to withstand the rigors of hard off-road use. The lower link arms are fabricated from thick-walled 2-inch tubing, ensuring they remain straight and durable under heavy loads. The full-width front crossmember not only secures the link arms at the ideal geometry but also reinforces the Gladiator’s frame, enhancing chassis rigidity.

All joints utilize Fabtech’s 5 Ton spherical bearings, known for their longevity and smooth operation, reducing maintenance and noise compared to traditional rubber bushings. The coil springs are dual rate and corner-specific, providing a comfortable ride on pavement while allowing maximum articulation off-road.

Installation & Fitment:

This suspension kit is designed for 2020 Jeep Gladiator 6-cylinder models, including Launch Edition, Overland, Rubicon, and Sport trims. Installation requires welding and some exhaust modifications or the addition of an aFe loop delete pipe (part #48-48024) to accommodate the new suspension geometry. Heavy off-road use on 4-door models may also necessitate upgraded driveshafts (front FTS94057, rear FTS94068).

Fabtech’s design ensures that the kit works with standard fenders and supports tire sizes up to 35x12.5R20 with minor trimming. For high clearance fenders, tire sizes up to 37x12.5R20 are supported with cutting required. Wheel sizes range from 17x9 to 20x9 with appropriate backspacing.
