    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.

    • If you have a 2.5" lift and do not want to install any additional parts when you remove the coil spacers- we would suggest getting coil springs rated for 2.5" of lift. 4" coil springs will require you to upgrade a lot more parts and would give you 4" of lift.

    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...

    • I do not recommend using the Teraflex 4 in. Coil Springs-rear pair with a 3.25" front spring, as all springs eventually sag and this will create a fairly large height difference front to rear. A 3.25" spring with a higher spring rate would be more ideal to keep an even ride height but also allow for increased weight capacity.

      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!
