 Manufactured in the U.S. using only high-strength chromoly materials, RCV Performance Ultimate 30 spline CV Axle set simply replaces your weak Toyota axle shafts with a new high-strength design. The factory axles were designed with 30 splines at the differential, and neck down to 27 Spline at the CV creating a common failure point. This axle set upgrades the weak 27 splines at the CV to a 300M 30 spline race eliminating the need to neck down the shaft.

Tests prove Ultimate CV Axles to be twice as strong as OEM shafts, and they're just as tough at a straight angle as they are at extreme angles. Even if you have big tires and big power there are no worries. Ultimate CV Axles are low maintenance and operate with a smoothness you can feel - whether off road or on the street.

Axle set includes right and left inner axle shafts & 2 pregreased CV joints. Black oxide coating is standard, We can accommodate custom length inner shafts as well if needed.

What makes these axles unique among any other axle set is that the inner race is made from 300M. You can tell that the race is 300M by a slight discoloration from the rest of the birfield. These are the only birfields that have this billet 300M race.

Please add in if needed any custom axle lengths are needed.
