The TeraFlex PRO LCG suspension system is designed for the aggressive off road enthusiast that wants the best suspension performance for both rock crawling and high speed performance. The PRO system allows the vehicle to tackle the toughest rock crawling trails of Moab, and speed on the dunes at Glamis with balanced suspension movement. The PRO system is the best Dual-Sport system allowing complete suspension movement, with controlled handling at highway speeds. The PRO system uses the TJ traditional front five-link suspension configuration, but expands the performance. Our front upper arms are over 9 inches longer than stock arms and will withstand the abuse and stress that are common with extreme trail vehicles. A heavy duty front adjustable trackbar is included in the system to maximize strength in the front axle for superior durability and control during high stress turning and suspension movement.
