In the pursuit of just a "tad" more lift, I got a set of 19/60 OEM springs for the Jeep. The Jeep is an 09 X 4 door with hard top and tow package. The Jeep had 17 and 18 in front and 58's in the rear. I was meticulous in measuring the before and after heights at several places to be able to determine if the swap was actually worth the money/effort. I did the swap 4 weeks ago.....I wanted to let the springs "settle" to get a final measurement before I posted the results on here. The front gained 3/4". The rear gained 7/8". After an alignment to get the "toe" set and the steering wheel re-centered, there is really not a perceivable difference in the ride. With the Tera Flex Leveling kit and these springs and all other suspension components stock, the caster is 3.6 and 3.7 degrees. All-in-all, I was pleasantly surprised with the amount of lift. Now time for new tires......
