        5 Top Rated Questions

        I would like to lift my Jeep a total of 4" so I saw these Springs. will I need to also purchase the 4" rear Springs as well to get a level look.

        • Your Jeep has a slight rake from factory, so if you are looking for a perfectly level setup, you will need to determine the difference. If you're lifting the vehicle, you need both front and rear springs.

        Are these 4 inch coils for a 4 door or 2 door?

        • They will work for both 2 door and 4 door models.

        If I currently have a 3.5 lift inch kit from Rubicon express, and upgraded my shocks to Fox Shocks 4 inches, would I also need to change my coils too?

        • If your fox shocks are rated for just 4", then yes you would want to upgrade to a 4" lift. If your shocks are rated for 3-4", the current lift you have would be fine. We suggest having the correct lift for the shocks you are adding to avoid the shocks failing early.

        Can I replace the springs on a 3.5” pro comp lift with these? Curious if the .5” will make a difference?

        • You can replace the springs with the Teraflex 4 in. Front Coil Springs but you may over extend your front shocks if they are not rated for 4" additionally it may require adjustable control arms if you already do not have any to adjust your angles for the additional height or require readjustment of your adjustable control arms if you already have some. As well as it could also require a couple other components depending on your current set up.

        Retainer Kit/Hardware. Good afternoon, Do I need to purchase a Coil Spring Retainer Kit/hardware? Jeep already has the RC 4" Lift on it. Was this way when I bought it. Thanks

        • The Teraflex 4 in. Coil Springs-front pair (07-17 Wrangler JK) may or may not require a Coil Spring Retainer Kit. This will depend based on the tools you currently have available. This should work with your RC kit a long as major modification was not done to the spring seat.

            Awesome coil springs!

            I got old man emu 4” lift on my jku heavy load springs I added winch, bumper, tire carrier.. Ride was harsh and stiff. Ended up replacing the coil springs with Teraflex front and back these coils made a huge difference and my Jeep did not sag due to additional weight. Can’t go wrong with Teraflex!

            Teraflex 4 in. Coil Springs-front pair (07-15 Wrangler JK)

            I had lifted my 2010 Jeep Unlimited Rubicon with the JK Wrangler 2.5" Performance Budget Boost from Teraflex. The front of my JKU sat 2" lower in the front after installing the lift. I didn't like the jacked up look at all. I wanted a level stance. I ordered these coil springs to eliminate the 2.5 inch Teraflex coil spacers and raise the front end 2 inches. To sit at least level. After installing the new coil springs and leaving out the factory isolator. I used the bump stop extensions from Teraflex also. The installation took maybe an hour total to install the new coil springs. After install the new coil springs lifted the front end 2.5 inches. I figure after or if the new coil springs do settle. My JKU will have a level stance. Right now my JKU sits a half inch higher in the front. Which looks a ton better then having it jacked up in the back. I have a Smitty front bumper with a 9500lb. winch on the front. The total weight of the new winch and bumper is around 150lbs. I love the new look/updated look. If you're looking to do the same thing or have the same issue. These coil springs will solve the problem.
