Built to Handle the Extra Wheelbase of Your Gladiator
The Jeep Gladiator carries a longer wheelbase than the Wrangler, which puts extra demand on rear suspension geometry once you add a lift or larger tires. The RK07380B rear lower control arm pair is engineered specifically around those JT proportions to keep your rear axle properly located on and off road.
Key Features
- RK07380B X Factor Series rear lower control arms built for the Gladiator's longer wheelbase
- Reinforced construction designed to resist bending and flex under heavy loads or towing
- Durable black finish resists corrosion from trail debris and road salt
- Direct bolt on installation at factory mounting locations
- Improves rear axle control when paired with a lift kit or larger tire package

Control Arms
Control arms are the key suspension linkages that connect the wheel hub and knuckle assembly to the vehicle frame, controlling wheel travel through both compression and droop cycles. Worn OEM control arms with loose ball joints or deteriorated bushings cause vague steering, tire wear, and handling inconsistency that only go away with replacement or upgrade.Popular UpgradesTubular steel upper control arms for lifted trucks and SUVs are the most popular upgrade in the control arm category, correcting the geometry compromised by a suspension lift and restoring proper caster angle and ball joint centering. Adjustable upper control arms allow alignment angles like caster and camber to be dialed in precisely after a lift or lowering modification. Replacement lower control arms with polyurethane or solid aluminum bushings improve response and longevity compared to worn OEM rubber mounts.Why do I need new control arms after a lift kit?A suspension lift changes the angle at which the OEM upp...
