4340 Chromoly 30/30 spline Birfield KIT
NITRO CHROMOLY Birfields & Axles - Now available for Toyota applications!
Toyota Trucks & Landcruisers 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 offroad use. Nitro Gear & Axle has addressed this by offering a range of Heavy Duty Chromoly Birfield Joints & Axle Shafts.
-NITRO 30/30 Kits feature axles that have 30 splines at both ends, eliminating the factory neck-down. Fully compatible with factory or aftermarket carriers, lockers, & hubs.
-High strength Chromoly Material featuring State of the art machining, heat-treating and polishing processes for uniformity and ultimate in stength.
Lifetime Warranty against breakage. Serviceable
