JFTJ - Front Kit - Timbren Suspension Enhancement System

The Timbren JFTJ SES is a front suspension enhancement system for the Jeep Wrangler made between 1997 and 2026 and the Jeep Gladiator made between 2020 and present.

Heavy front-end loads — a steel bumper, winch, or trailer tongue weight — can cause your Jeep to sag and sway, compromising handling and safety.

How? Our Aeon® springs deliver a progressive spring rate. As load increases, our springs push back harder, eliminating front-end sag and sway while providing a safe, smooth ride. The natural rubber properties of our Aeon® springs also cushion road shock, reducing hard hits from driving over bumps and dips.

This SES suspension upgrade replaces the jounce stop inside the coil spring. Each laser-cut piece of steel is precision bent and powder-coated to ensure a quality fit.
