The hardcore rock crawling suspension choice for your 4-Door Diesel Jeep Wrangler JL is a J-Krawl 3.5" lift kit. The complete system is designed for maximum articulation, strength and adjustability. Components include J-Flex or J-Link Upper and Lower Control Arms, JSPEC dual rate coil springs, custom-valved shock options tailored to your needs, including FOX Adventure Series shocks, an adjustable front track bar, a rear track bar bracket, Quicker Disconnect front sway bar end links, and bump stop extensions. J-Krawl builds off Jeep's factory suspension mounting points and upgrades everything front to rear.

Adjustability is important for fine tuning suspension geometry. J-Krawl delivers. Dial in front caster, rear pinion and overall vehicle wheelbase. The JKS Engineering team spent a lot of time dialing in the FOX shock valving and spring rates to suit J-Krawl's combination of parts as well as oversized wheels and tires. You'll be impressed with the stability and compression/rebound response. Take your Jeep's off-road performance and strength to the next level. It should be noted that an aftermarket front driveshaft is strongly recommended due to potential additional travel.
