The Yukon Gear & Axle pinion nut is specified for Suzuki Samurai, Toyota 8" units including V6 and Landcruiser (fine spline), and T100/Tacoma models with factory lockers, supplied as M20 x 1.5 thread and using a 30mm socket. It’s intended as a replacement nut for those pinion assemblies during service or rebuilds, accommodating fine-spline and locker-equipped applications. Yukon’s small parts support axle maintenance with matching components.
