For those who would like the unsurpassed ride, suppleness and all around performance of the Trail Tough "Epic Trek" system without the 6 1/2" of lift height, this IS the kit! It provides only 3 1/2" of lift and uses a 29" - 31" tire. We still use all of the super trick components, "Bonz Eye" rear springs in front, "Bonz Eye" YJ springs, "TT" Towers, "Epic Trek" nitrogen rebuildable shocks, and Delrin bushings for the chassis eyes for tight steering response and handling. With this kit - while some welding is suggested - it is optional, not required. 8" wheels are recommended with 3 3/4" backspace. As with all of our new front Missing Link kits, the drop shackle function is optional - simply bolt it in the fixed position or leave it unbolted for even more articulation.
