Toyota Trucks & Land Cruisers are well known for their strength & reliability all over the world. Out of the box they feature some pretty great drivetrain, but they do have their limits. The factory axles are 30 Spline at the diff, but neck down to 27 Spline at the birfield creating a failure point. Additionally the factory Birfield joints are not built to withstand the added stress of larger tires and heavy off road use. Nitro Gear & Axle has addressed this by offering a range of Heavy Duty Chromoly Birfield Joints & Axle Shafts.
