Toyota Trucks and Land Cruisers are well known for their strength and 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 and Axle has addressed this by offering a range of Heavy Duty Chromoly Birfield Joints and Axle Shafts. Nitro Gear and Axle strives to provide the highest quality differential and axle components available. We take the steps necessary to ensure our parts are dependable. Our product range is continually growing to meet the needs of consumers for new ratios and applications. At Nitro we know differentials, and know what it takes to provide you with high quality components.
