ICON Vehicle Dynamics 2007-2018 Jeep Wrangler JK 4.5" Lift Front Dual Rate Spring Kit

The ICON Vehicle Dynamics Dual Rate Spring Kit delivers 4.5 inches of front lift over stock for 2007–2018 Jeep Wrangler JK models, using a dual-rate coil design that balances on-road comfort with off-road bottoming resistance. The kit fits both 2-door and 4-door JK builds, though 2-door models sit slightly higher than 4-door models at the same lift height.

Dual-Rate Design: Comfort and Control in One Spring

The dual-rate coil construction uses a softer initial spring rate for everyday driving comfort, then transitions to a firmer secondary rate as the suspension compresses further. That progression means the front end absorbs small road imperfections without harshness, while still resisting bottoming out on harder hits on the trail. This is a meaningful difference from a single-rate spring that forces a compromise between the two.

More Wheel Travel When Paired with ICON Shocks

Running these springs alongside ICON shocks unlocks additional wheel travel beyond what stock geometry allows. Greater travel keeps tires in contact with uneven terrain longer, improving traction and stability on technical off-road sections. The springs are also designed to accommodate larger tires: 35x12.50-inch tires fit with OEM fenders, and 37-inch tires fit with minor modifications or aftermarket high-clearance fenders (test fitment is recommended for 37-inch applications).

Bolt-On Installation and Long-Term Durability

The 100% bolt-on design requires no cutting or fabrication. A dual-stage semi-gloss black powder coat finish protects against corrosion. Every spring in this line carries a lifetime guarantee against sagging and breakage. The kit is ICON 1K tested, validated under rigorous off-road conditions for tune, performance, strength, and durability before release.

Specifications

Who This Is For and Isn't

This spring kit suits 2007–2018 Jeep Wrangler JK owners (2-door and 4-door) who want 4.5 inches of front lift, improved off-road capability, and the ability to run larger tires. It is a strong fit for builds that already include or plan to include ICON shocks, where the full wheel-travel benefit is realized.

This kit does not fit Jeep Wrangler JL, TJ, or any other platform; fitment is exclusive to the 2007–2018 JK generation. It covers the front axle only; rear lift requires separate components. Buyers running 37-inch tires on stock fenders should expect that minor modifications or high-clearance fenders will be needed, and test fitment is recommended before committing. Actual lift height may exceed 4.5 inches on vehicles lighter than a typical accessorized JK build.

Common Questions

Does this spring kit fit both 2-door and 4-door Jeep Wrangler JK models?

The ICON Dual Rate Spring Kit fits both 2-door and 4-door 2007–2018 Jeep Wrangler JK models. Because 2-door JKs carry less weight over the front axle, they will sit slightly higher than 4-door models at the same 4.5-inch nominal lift height.

Do I need ICON shocks to use these springs?

The springs install as a bolt-on replacement without requiring ICON shocks. Pairing them with compatible ICON shocks is what unlocks the additional wheel travel the dual-rate design is capable of; stock or other-brand shocks will limit available travel.

Will 35-inch or 37-inch tires clear with this kit?

35x12.50-inch tires fit with OEM fenders at this lift height. 37-inch tires will fit but require minor modifications or aftermarket high-clearance fenders; test fitment is recommended before purchasing 37-inch tires for a JK running this spring kit.

What does the lifetime guarantee cover?

The ICON Dual Rate Spring Kit carries a lifetime guarantee specifically against sagging and breakage. Refer to ICON Vehicle Dynamics' published warranty terms for full coverage details and any conditions that apply.
