A 4.5 in lift opens room for larger tires, but it also pushes caster and pinion angles out of range and makes the front end nose-dive under braking. Many owners want the height without a rough ride.
The Sport ST4 combines 4.5 in lift coil springs with front control arm Sport Frame Brackets, which correct steering geometry and reduce brake nosedive, plus front lower and rear lower track bar brackets that center the axles. Progressive bump stops and front sway bar quick disconnects are tuned to the lift height, and installation is bolt-on with no cutting or welding.
Install it on Friday, add shocks, and the Jeep is ready for larger tires with highway manners intact.
