These worked perfect for my 2.5 inch leveling kit on 2021 jeep gladiator high altitude, built extremely well and much superior to oem, i adjusted them about a 1/2 inch longer than stock and when the alignment was done my caster angle was 6.2 both sides. No more wandering all over the road.
Good instructions and fairly easy install. Definitely worth the money.
Replaced my rough country arms with the super flex. 10x better less binding with flexing along with tightening up the front end and steering.
