JKS JSPEC197FRS J-Krawl 2.5" Lift Kit Diesel JL 4-Door FOX 3.0 FRS Shocks Rubber Bushings

The JKS JSPEC197FRS J-Krawl 2.5" Lift Kit is a complete, high-performance suspension system purpose-built for the 4-Door Diesel Jeep Wrangler JL. Engineered for maximum articulation, strength, and adjustability, this kit provides a full front-to-rear overhaul of the factory suspension — delivering serious off-road capability without sacrificing on-road manners.

This specific configuration pairs rubber-bushed J-Link upper and lower control arms with top-tier FOX 3.0 Factory Race Series (FRS) Internal Bypass (IBP) shocks: DSC-equipped remote reservoir units up front and DSC-equipped piggyback units out back. The FOX 3.0 FRS shocks are custom-valved by JKS engineers to perfectly complement the spring rates and suspension geometry of the J-Krawl system.

Key Features:

• 2.5" of suspension lift tuned specifically for the heavier Diesel powertrain in the 4-Door Wrangler JL platform
• FOX 3.0 FRS IBP Front Shocks with DSC — Internal Bypass, remote reservoir design with Digital Shox Controller for on-the-fly damping adjustment
• FOX 3.0 FRS IBP Rear Shocks with DSC — Piggyback reservoir configuration with Digital Shox Controller for precise rebound and compression tuning
• JSPEC dual-rate progressive coil springs — custom-wound springs that deliver a plush highway ride while stiffening progressively under compression for trail performance
• Rubber-bushed J-Link control arms — factory-style, maintenance-free rubber bushings installed at both ends to reduce NVH (Noise, Vibration, and Harshness) for a quiet, controlled daily driver
• All eight adjustable control arms included — upper and lower, front and rear — allowing fine-tuning of front caster, rear pinion angle, and overall wheelbase
• Adjustable front track bar and rear track bar bracket to correct axle centering under the vehicle
• Quicker Disconnect front sway bar end links for fast, tool-free sway bar disconnects on the trail
• Bump stop extensions and brake line relocation brackets included for full-travel safety
• Builds off factory suspension mounting points — no cutting or major fabrication required

An aftermarket front driveshaft is strongly recommended when running this system due to the increased suspension travel. The J-Krawl system is the go-to choice for Jeep enthusiasts who demand a fully adjustable, purpose-built suspension upgrade capable of tackling technical rock crawling terrain while remaining comfortable on the street.
