TeraFlex JLU 4-Door: 3.5” Sport ST3 Suspension System

SKU 1513000

These all-inclusive TeraFlex Sport ST (Street & Trail) Suspensions Systems deliver true street & trail (ST) performance and capability in a dependable and maintenance-free package.

With its Front Control Arm Sport Brackets, the 3.5” Sport ST3 Suspension System focuses on ride and handling. These direct bolt-on brackets restore caster on taller lifts for improved ride quality and reduced brake nose dive. TeraFlex Sport Brackets are “built to take a hit.” The Front and Rear Track Bar Brackets correct axle position to provide a more positive steering feel.

All Sport ST Suspension Systems feature coil springs and bump stops optimized for stated lift height as well as tire and component clearance.

The Sport ST3 and Sport ST4 feature our Front Control Arm Sport Brackets that optimize caster and pinion angles to restore front suspension geometry. These systems also include Front (3.5”+) and Rear (2.5”) Track Bar Brackets to improve steering response, optimize vehicle roll center, and reduce body roll for unsurpassed handling.

This results in a simple “install and drive” bolt-on installation with no cutting, welding, or alignment required. These maintenance-free suspension systems provide superior on-road ride quality and comfort with maximum off-road flex. TeraFlex suspension systems provide reduced noise, vibration, and harshness (NVH).

Sport ST Suspension Systems can be installed on Friday, wheeled on Saturday, and driven to church on Sunday!
