The Eaton Posi limited-slip differential prevents wheel slip before it can get started. To do that, carbon disc clutch packs, preloaded by a central spring assembly, are located behind each differential side gear. When torque input increases the clamping load on the clutch packs increases. That causes the chatter-free clutch packs to grab and transfer power to the other wheel. Muscle cars, hot rods and mild off-road vehicles should look to Eatonss limited-slip differential for their traction answers. And the fact is, Eatons Posi units are virtually bullet proof.

What is Route and Green Package Protection?

Route's Green Package Protection is a package projection solution that helps you cover your order in the event that your order gets lost, stolen, or damaged while in transit while also protecting the planet. We know it is frustrating to have something happen to your order, so we've partnered with Route to offer added assurance that you're supported, no matter what. Green Package Protection can be added during checkout.

Every time you add Green Package Protection to your order, Route donates to support an agroforestry initiative that removes COfrom the air and promotes a flourshing ecosystem.

You can also utilize the Route App to visually track all of your online orders in one place and easily file a claim with their team. Whether you're tracking via the Route App or online, Route's real-time shipping updates keep you in the loop throughout every part of your delivery. Haven't downloaded the app yet? Download here.

  • Domestic packages are not considered lost until after the 7th day without a tracking update.
