🧾 Overview
The TeraFlex 2.5" Coil Spring Base Lift Kit for the Jeep Wrangler JK Unlimited (4-Door) is engineered to increase ground clearance and off-road capability while preserving factory ride quality and drivability. Designed around properly developed suspension geometry, roll center correction, and load tuning, this system allows larger tires to be fitted without compromising stability or on-road handling.
This no-shock version of the kit is ideal for Jeep owners who plan to reuse existing shocks or upgrade separately. By excluding shocks and shock extensions, the kit provides a solid foundation for a custom suspension setup while maintaining full compatibility with factory stability control systems.
