A Yukon Gear & Axle adapter sleeve that lets a GM 8.6in or 9.5in yoke accept a late-model triple‑lip pinion seal. The sleeve adapts a standard yoke bore to the later seal design, enabling use of the triple‑lip seal without changing yokes. Intended for general replacement and performance axle service, it fits the stated GM 8.6 and 9.5 inch applications where a triple‑lip seal installation is required.
