No two Jeeps are exactly the same. Variations in weight and axletube diameters make a big difference in how high your Jeep actually sits when it’s all done. Since we wanted to stay low and save some cash, we made sure we had several coil springs on-hand. The T&T kit uses rear TJ coils, but with our rear armor and rear bumper (“Hard Ass,” Aug. ’10), we knew we would need more than just regular TJ coils. LJs are heavier than TJs, so the factory coils have a higher spring rate. Shown here from left to right are: factory LJ coil, factory LJ Rubicon coil, and used Old Man Emu 3-inch-lift coil.
