ICON Vehicle Dynamics 2020-Up Jeep JT Gladiator 1.5" Lift Rear Multi Rate Coil Spring Kit

The ICON Vehicle Dynamics Rear Multi Rate Coil Spring Kit delivers 1.5 inches of rear lift for 2020 and newer Jeep JT Gladiators using a triple-rate spring design that ICON engineers specifically for droop, ride, and overload conditions. The kit ships as a pair of rear coil springs and requires a compatible sway bar relocation or link kit (sold separately) to complete the installation.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Three Rates, One Spring

Most coil springs use a single spring rate, which forces a compromise between on-road comfort and off-road bottoming resistance. The ICON triple-rate design resolves that tradeoff by engaging a softer droop rate as the suspension approaches full extension, a moderate ride rate at normal ride height, and a progressively firmer overload rate under compression. The result is a spring that absorbs small trail chop without harshness and resists bottoming on hard hits without the stiff, jarring feel of a single-rate overload spring.

More Rear Wheel Travel

When paired with ICON rear shocks, these coil springs produce a 23% increase in rear wheel travel over stock. Greater wheel travel keeps the rear tires in contact with uneven terrain longer, improving traction and stability on off-camber surfaces and rocky trails. The springs are ICON 1K tested, validated under rigorous off-road conditions for performance, strength, and durability before reaching production.

Corrosion Resistance Built In

Each spring receives a dual-stage powder coat finish that protects against rust and corrosion through repeated exposure to mud, water, and road salt. ICON backs every coil spring in this line with a lifetime guarantee against sagging and breakage, so the lift height and spring rates remain consistent over the life of the vehicle.

Specifications

Who This Is For and Isn't

This kit suits 2020 and newer Jeep JT Gladiator owners who want 1.5 inches of rear lift with improved off-road wheel travel and on-road ride quality. It is a strong fit for overlanders and trail drivers who already run or plan to run ICON rear shocks, where the 23% wheel travel increase is fully realized.

These springs fit only the 2020-up Jeep JT Gladiator and address rear lift only; they do not fit Wrangler JL, JK, or any other Jeep model, and they do not address front lift. Installation cannot be completed without a sway bar relocation kit (Part #22062) or sway bar link kit (Part #22070), neither of which is included. The 23% wheel travel figure applies only when paired with ICON rear shocks; travel gains with other shocks are not stated.

Common Questions

Do these springs work on Jeep Wrangler JL or JK models?

The ICON Rear Multi Rate Coil Spring Kit (SKU 22066) is engineered and validated for the 2020 and newer Jeep JT Gladiator only. It is not listed as compatible with the Wrangler JL, JK, or any other Jeep model.

Is a sway bar kit included, or does it need to be purchased separately?

A sway bar relocation kit or sway bar link kit is required to complete the rear coil spring installation on the JT Gladiator but is not included with this kit. ICON offers the sway bar relocation kit as Part #22062 and the sway bar link kit as Part #22070, both sold separately.

Does the 23% wheel travel increase apply with any rear shock?

ICON states the 23% increase in rear wheel travel when these coil springs are paired with ICON rear shocks. A travel figure for use with other brands' shocks is not stated, so that gain should not be assumed outside of an ICON shock pairing.

What does the lifetime guarantee cover?

ICON's lifetime guarantee on these rear coil springs covers sagging and breakage. The guarantee applies to all ICON coil springs in this line. Specific terms, claim procedures, and any exclusions are governed by ICON Vehicle Dynamics directly.
