The all-inclusive TeraFlex Sport RT4 Suspension System delivers true rouge trail performance and capability in a dependable and maintenance-free package! Developed for the Jeeper looking for a stable commute and comfortable trail performance, the 4.5” Sport RT4 Suspension System features all eight adjustable Alpine Long Control Arms. The Alpine Control Arms optimize steering geometry for improved highway handling. The additional lift height over factory clears larger diameter tires without compromising on- or off-road stability. The RT4 also adds Alpine Forged Adjustable Front and Rear Track Bars that improve steering response and helps center the axle to optimize vehicle roll center.
