The arm body is machined from 1-3\/8\" solid steel stock — a deliberate design choice for rear upper arms where a slim profile is required to clear the frame rail, body tub, and bed structure under full articulation. Solid stock at this diameter delivers higher tensile and bending strength than a comparable hollow tube, which is critical for the rear upper arm's role in controlling axle rotation and pinion angle under load. Both the adjuster end and the axle-side mount use Clayton's GIIRO dual-durometer bushing — a softer outer durometer for NVH isolation and a stiffer inner core for lateral load resistance. Self-centering geometry allows 30° of misalignment without binding through the full droop-to-compression cycle. The arm tube and housing are identical to the Premium version (COR-1910230), which uses a Johnny Joint forged rod end at the adjuster. Adjusters are field-swappable between Overland+ and Premium spec without replacing the arm. Lifetime warranty. Made in the USA.
