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

  • Features heavy-duty J-Flex upper and lower control arms to improve strength and correct geometry.

Brand Overview

Since 1989, JKS Manufacturing has developed some of the world’s most widely used and respected products for Jeep vehicles. It all started when we pioneered the original Quick Disconnect brand of quick-release sway bar disconnects. Since then our product range has expanded to include such favorites as the ACOS line of height-adjustable coil spring spacers, and perhaps our most advanced creation to date, J-Spec Suspension systems including the JK Front Coilover Conversion.
