TeraFlex JLU 4-Door: 4.5” Sport ST4 Suspension System

SKU 1514000

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.

The 4.5” Sport ST4 Suspension System’s higher lift height allows for larger tires and a dominating stance, while maintaining a comfortable and stable ride on both highway and trail. TeraFlex’s robust Front Control Arm Sport Brackets provide steering geometry correction as well as positive braking control with reduced nose dive.

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!
