ICON Vehicle Dynamics Ram 2500/3500 4WD Diesel 4.5-Inch Front Dual Rate Coil Spring Kit

The ICON Vehicle Dynamics 214010 is a front dual-rate coil spring kit delivering 4.5 inches of lift for 2003–2013 Dodge Ram 2500 and 2003–2012 Dodge Ram 3500 trucks equipped with 4WD and a diesel engine. The kit includes front sway bar drop brackets and installs with no cutting or fabrication required. Springs are rated specifically for diesel engine weight and are not compatible with gas-powered Ram 2500 or 3500 models.

Dual-Rate Design for On-Road Comfort and Off-Road Resistance

The coil springs use a dual-rate construction: a softer initial rate absorbs everyday road imperfections and keeps the ride composed on pavement, while a firmer secondary rate engages progressively under compression. That transition matters off-road, where a spring that stays soft through full travel will bottom out under load. The firmer secondary rate resists bottoming without making the truck feel stiff during normal driving.

Optimized for Diesel Engine Weight

Ram 2500 and 3500 diesel engines carry significantly more weight over the front axle than their gas counterparts. These springs are rate-matched to that load, which means the 4.5-inch lift height is achieved without the nose-high or nose-low stance that results from installing a spring calibrated for a lighter drivetrain. OEM wheels and tires remain compatible after installation.

Corrosion-Resistant Finish and Lifetime Coverage

Each spring receives a semi-gloss powder coat that resists corrosion from road salt, mud, and moisture. ICON backs these springs with a lifetime warranty against sagging and breakage, which means the lift height is not expected to diminish over the life of the vehicle.

Features

• 4.5-inch front lift: raises the front of the truck 4.5 inches over the stock ride height
• Dual-rate coil design: softer initial rate for on-road comfort, firmer secondary rate for off-road bottoming resistance
• Diesel-rated spring rates: calibrated for the front-axle weight of Ram 2500 and 3500 diesel engines
• Front sway bar drop brackets included: maintains sway bar geometry at the lifted height
• Semi-gloss powder coat: corrosion-resistant finish for long-term durability
• 100% bolt-on installation: no cutting, welding, or fabrication required

Who This Is For and Isn't

This kit suits owners of 2003–2013 Dodge Ram 2500 or 2003–2012 Dodge Ram 3500 trucks with 4WD and a diesel engine who want 4.5 inches of front lift, improved off-road suspension travel when paired with compatible ICON shocks, and the ability to run up to 35-inch tires on OEM or appropriately offset aftermarket wheels.

This kit does not fit gas-powered Ram 2500 or 3500 models, 2WD trucks, or any Ram 1500. Shocks are not included. Tires larger than 35x12.50" may require fender trimming and additional modifications not covered by this kit.

Common Questions

Will these springs work on a gas-powered Ram 2500 or 3500?

No. The ICON 214010 coil spring kit is rated specifically for diesel engines. The spring rates are calibrated for the heavier front-axle weight of diesel-equipped Ram 2500 and 3500 trucks; installing them on a gas model will produce incorrect ride height and handling characteristics.

Do shocks come with this kit?

Shocks are not included with the ICON 214010 coil spring kit. ICON notes that increased wheel travel is available when these springs are used with compatible ICON shocks, which are sold separately.

What is included in the box?

The ICON 214010 kit includes the dual-rate front coil springs and front sway bar drop brackets. No shocks, upper control arms, or other suspension components are included.

What wheel and tire sizes are recommended after installing this lift?

ICON recommends aftermarket wheels in 17x8.5" with 5.25" backspace (13mm offset), 18x9" with 5.50" backspace (12mm offset), or 20x9" with 5.50" backspace (12mm offset). OEM wheels and tires remain compatible. A 35x12.50" tire is the recommended aftermarket tire size; larger tires may fit but will require fender trimming.

Is this a bolt-on installation or does it require cutting or welding?

The ICON 214010 coil spring kit is a 100% bolt-on system. No cutting, welding, or fabrication is required. An installation guide is available for reference during the install process.
