The Premium tier is Clayton's highest-spec short arm system — it combines GIIRO dual-durometer bushing joints (road noise isolation, maintenance-free) with forged Johnny Joint adjusters (greaseable, rebuildable, 40° misalignment capability) at all eight control arm positions. This dual-joint architecture gives you the on-road comfort of GIIRO with the off-road articulation ceiling and long-term serviceability of Johnny Joints. At 4.5\" of lift, a front CV-style driveshaft is highly recommended to manage driveshaft angle and reduce vibration. 2012–2018 JK models require an exhaust spacer due to exhaust routing changes — available in the related items tab. Critical 2-door note: 2-door JK models will see approximately 1\" more lift than the advertised 4.5\" due to lighter vehicle weight. Ships at 145 lbs.
