High (1)

ARB RD140 fitment with Revolution F10.25-513L in the Sterling 10.5 housing (#300) — The rear runs a 10.25" ring gear (Revolution F10.25-513L) in the 10.5 housing with the ARB RD140 carrier (Ford 10.25/10.5, 35 spline, all ratios). Confirm with ARB or Revolution that the RD140 flange and ring gear bolt pattern match the F10.25 gear in this housing before ordering, and confirm the pinion depth starting point (owner note: add roughly 0.120" to the pinion depth stack).

Air locker air line service loop length at full droop (front and rear) (#303) — Measure the ARB air line service loop needed at each axle at full droop on the ORI struts (14" front, 16" rear travel), not at ride height. Sets the air line kit segment lengths from the manifold under the passenger seat (baseline estimates ~12 ft front, ~6 ft rear).
