Product Details
Yukon Gear & Axle is known for making strong drivetrain components, and this steel spool is a prime example for your Toyota. If you're building a dedicated off-road rig or a drag car, this spool is designed to replace your differential carrier assembly and give you 100% traction to both wheels, all the time. It's a straightforward way to get maximum grip when you need it most.
This spool is made from 8620 steel and then heat-treated for extra strength, which is crucial for the kind of abuse these types of vehicles can see. It's built to handle performance applications and ensure a long life. Keep in mind, this type of 100% locked differential isn't recommended for street driving because it can make turning more difficult. It's specifically for vehicles that are trailered or only used in controlled environments like a drag strip.
This particular spool is designed to fit the Toyota 8-inch differential found in 4-cylinder models. It installs directly in place of your stock differential carrier, making it a cost-effective upgrade for serious traction.
