The factory 5-leaf rear Wrangler spring pack (top) has been modified with an additional leaf under the main eye to help counter sagging. The flat Wrangler pack in a spring-over configuration nets the same amount of lift as the Rubicon Express 4.5-inch Extreme Duty spring-under pack (bottom). Although the eye-to-eye measurement at rest is nearly equal between the two springs, the spring-under pack will grow much longer upon compression and will offer less droop than the flatter Wrangler pack.
