If you're diving into the world of performance upgrades, let me tell you about the Motive Gear Differential Spool. This isn't just another part—it’s a game changer for anyone serious about their ride. Built for those who want to get the most out of their GM 8.5" rear end, this full spool is designed to handle the heat of both street and track. With a 28-spline count, it locks your wheels together for maximum traction, which is a must when you’re pushing your vehicle to its limits.

The spool is crafted from high-quality steel, so you know it’s built to last. The 45-degree pressure angle means it’s engineered for strength and durability, and it’s been tested under some serious conditions to ensure it won’t let you down when you need it most. Plus, it requires the use of bearing LM501349 and race LM501314, so make sure you’ve got those on hand when you install it. Trust me, you don’t want to skimp on the little things!
