The Rear Axle Bar and Internal CV upgrade for the 2020 Supra is now available. Taking what we've learned from many years of using the OEM Toyota Cores in stock form with good results we designed a New Chromoly 28-Spline Race/Cage specific for these to work with our 300m Material Axle Bars used on many of our other 1000hp Applications. We use High Quality Neoprene Boots and Metal Sealing Covers making these axles practically indestructible.
