        I'm running lightweight in the rear with a reduced weight bumper, a tire delete, and no armor. I'm looking for 4 inches of lift. Should I use these or should I go with shorter springs for the same amount of lift?

        • We recommend contacting Teraflex directly with the weights of your vehicle to verify the springs they recommend for this setup.

        what's the overall height of the springs and pounds per inch rating?

        • Unfortunately Teraflex does not advertise the spring rate or height for these springs.

        Hey I have a Rough Country 3.25 inch lift on my 2013 JKU. The rear coils also have a .75 spacer, can I upgrade to a 4inch spring to get rid of the sag in the back, I carry about 800 pounds of gear

        • We have not attempted running a setup like this, however you will most likely see more than the 3.25" of lift in the rear with these springs due to their higher spring rate.

        I currently have a Teraflex 2.5 inch suspension lift I purchased from you guys. It came with the 9550 shocks which I know are rated to handle a 4” lift. Can I replace the 2.5 springs with 4” springs? I have upgraded to the Teraflex track bar and starting stablizer.

        • If your shocks are rated for a 4" lift you can add the springs but you would also need to look into aftermarket adjustable control arms, new front and rear driveshafts and all the other suspension & driveline components needed for a 4" lift.

        Hi, i have Teraflex 3 inch lift(with shocks) on my jku, looking to upgrade the spring to 4 inch and add additional 0.5 inch teraflex coil spring spacer, will my Teraflex shocks fit? what other components do i need to make this work? Thanks!

        • You will need new shocks rated for your new lift height of 4.5" with your new Teraflex 4 in. Coil Springs and 0.5" spacers.

        I have a 2.5 inch RC lift that included shocks and coil spacers. I would like to upgrade the coils. Can I use 4 in coils to eliminate the coil spacers? If I just replace the coils with 3 in coils, the ride height would be lower. 1 answer
        I currently have the Rough Country 3.25" budget lift. The back end is starting to sag. More importantly, I drive across country for work, and tend to haul plenty of gear with me, and I will be doing some overlanding this summer. Can I put these springs in, in place of the 3.25" springs, to accommodate for the added weight, and prevent sagging? Thanks... 1 answer

            In a JKU i got about 3.7 inches of lift out of these - no sagging and an excellent ride. Cant go wrong with Teraflex!
