FITMENT

For Jeep owners who demand maximum off-road performance and suspension adjustability, the JKS J-Krawl 4.5” Lift Kit is the ultimate high-articulation upgrade for the 2018–2025 Jeep Wrangler JL. This system is built around a full set of JKS heavy-duty J-Link adjustable control arms, available with either OEM-style rubber bushings or advanced Flex Ends that promote superior suspension articulation. The J-Krawl system offers precise tuning of caster, pinion angle, and wheelbase—ideal for aggressive tire setups and serious trail use. Paired with JL-specific dual-rate coil springs, this kit provides a smooth, controlled ride on-road while delivering maximum off-road flex and axle stability.

To maintain proper suspension geometry and handling, the kit includes a front adjustable track bar and rear track bar bracket to keep the axles centered, along with extended sway bar links for improved articulation. Bump stop extensions are included to prevent over-compression, while brake line relocation brackets ensure safety and functionality at full suspension travel. Designed for Jeepers who crawl technical terrain and demand a fully tunable suspension setup, this kit supports up to 37" tires and is compatible with both stock and aftermarket driveshafts (aftermarket recommended for extreme off-road use).

Whether you're building a weekend crawler or a dual-purpose overland rig, the JKS J-Krawl 4.5” Lift Kit gives you the control, clearance, and confidence to push your Wrangler to its limits. If you're serious about suspension performance and full adjustability, this is the kit that delivers.

Features & Benefits

  • Aftermarket drive shaft is required.
  • Drag link flip is required for steering correction. Additional heavy duty steering components are reccomended.
  • It recommended to use a strong steering stabilizers. In our testing there a lot of variation between jeeps and how they react to Tire size, Lift heights, Factory steering components, Worn parts. Increasing Caster and Toeing in the tires can help but sometimes a strong stabilize is required to prevent steering wheel shimmy in some vehicles.

Recommended Tires & Wheels

  • 37 x 12.5 with 17 x 8 and 5 in. Backspace
  • 40 x 13.5 with 17 x 8 and 4.5 in. Backspace

    Picking the Right Coil Springs

    JKS J-Rated Suspension Systems feature custom wound, progressive rate coil springs. That means the spring rate increases as the spring is compressed. You and your Jeep enjoy a plush ride during low load driving scenarios such as highway cruising with increased performance as each spring compresses. If you carry a significant amount of extra gear in your Jeep, some J-Rated suspension systems are available with optional high-rate coil springs to support the additional weight.

    Control Arm Bushing Selection

    Flex Ends:

    Forged flex end and jam nut Flex end design allows for 30-degrees of misalignment (15 in either direction) for impressive articulation and are greaseable to ensure long bushing life. Completely rebuildable and serviceable on the trail with our JKS Flex Joint tools (link to tool).

    Rubber bushings:

    Engineered specifically to reduce NVH characteristics (Noise, vibration, harshness), these factory style maintenance-free rubber bushings come pre-installed at both ends and will ensure a quiet, controlled ride with hassle-free operation in any environment.
