JKS Manufacturing JSPECTM 3.5” J Kontrol Suspension System for 07-17 Jeep® Wrangler and Wrangler Unlimited JK

The Quadratec® Difference
These JSPEC J Kontrol systems take the off road capable daily driver to the next level, bringing JKS’s off road expertise to urban maneuvers. The J Kontrol system contains JKS’s beefy control arm relocation brackets with an OEM style draglink flip kit for the ultimate combination of durability, road comfort and unrivaled street handling. JKS took the time to recreate the idea of a control arm bracket that not only flattens the front control arm angles and corrects alignment, but meets JKS high standards as a durable, high quality component that can take a beating off road. The draglink flip kit levels the draglink, completely eliminating any hint of bump steer and has a clean, easy installation with an OEM fit and finish. As with any JSpec system, J Kontrol systems are fully customizable to meet your needs.
