Designed to enhance performance across a variety of demanding terrains—including rock crawling, aggressive trail riding, and extended overland expeditions—this kit provides a balanced combination of comfort, durability, and capability. Featuring a complete short arm suspension system, it maintains factory lower control arm mounts for straightforward installation while significantly improving suspension travel and ride quality.

Fabtech’s dual rate coil springs and advanced shock valving ensure a compliant ride on and off the trail, making it a versatile upgrade for both weekend adventurers and full-time off-roaders.

Key Features:

Fabtech’s Trail Diesel Suspension Kit incorporates advanced engineering and premium components to optimize your Jeep Gladiator’s off-road performance:

• 5-inch lift height with dual rate coil springs tuned for side-to-side vehicle balance and increased suspension travel
• Complete short arm suspension system using factory lower control arm mounts for ease of installation
• Heavy-duty Fabtech lower link arms constructed from thick wall steel tubing, guaranteed never to bend
• Large polyurethane bushings paired with Fabtech 5 Ton Joint® for enhanced durability and quiet operation
• Draglink Flip Kit and heavy-duty Track Bar bracket to correct steering geometry and maintain factory roll center
• Front and rear bump stop extensions to prevent suspension over-cycling and protect components
• Shock absorbers: 2.25 DLSS shocks specifically valved for the Gladiator’s weight and suspension dynamics
• Supports tire sizes up to 40x12.5R20 with appropriate fender modifications
• Designed exclusively for diesel-powered Jeep Gladiator models

Construction & Design:

Fabtech’s suspension kit is built with robust materials and precision engineering to withstand the rigors of extreme off-road use. The lower link arms utilize thick wall steel tubing, providing exceptional strength and resistance to bending under heavy loads. Polyurethane bushings reduce noise and vibration while maintaining articulation, and the innovative Fabtech 5 Ton Joint® ensures long-lasting performance with minimal maintenance.

The dual rate coil springs are corner-specific, allowing the suspension to remain level side to side and providing a progressive spring rate that balances comfort and load capacity. The first stage offers a soft, compliant ride, while the second stage supports payload and absorbs large impacts at higher speeds. Heavy-duty brackets and flip kits maintain proper steering geometry and axle positioning, preserving handling characteristics despite the increased ride height.

Installation & Fitment:

This suspension kit is designed for a direct bolt-on installation using factory lower control arm mounts, simplifying the upgrade process without the need for extensive modifications. Minor trimming or cutting of fenders may be required depending on tire and wheel size, especially when fitting larger 40-inch tires with high clearance fenders. The kit fits the following Jeep Gladiator models equipped with diesel engines:

• 2021 Jeep Gladiator 80th Anniversary
• 2022 Jeep Gladiator Altitude
• 2023 Jeep Gladiator Freedom
