The Yukon Gear & Axle replacement bare case for GM 8.5 and 8.6‑inch Yukon Dura Grip applications is cast and machined to match factory tolerances and fits both 28‑ and 30‑spline setups. Yukon specifies this carrier for Dura Grip units only; it is not a replacement for a stock Positraction carrier and is supplied without internal spider gears.
