Review on 4.5-Inch Rubicon Express RE1355 Coil Spring Upgrade 🚙 for Jeep TJ - Enhancing Performance and Ride Quality by Jared Winebrenner

I have been using these springs on my 05 Rubicon Unlimited for over 10 years now. They ride well and offer a full 4.5 inches of lift. After about 8.5 years the passenger side started to sag about 3/4 inch. The good news is they are backed by a lifetime warranty from Rubicon Express, which is also owned by the company that owns 4 Wheel Parts. I contacted my local 4 wheel parts store and exchanged my old springs for new ones for free. Excellent customer service.
