30 Spline 300M CV Axle Set for Toyota Land Cruiser – Reinforced for Extreme Terrain
Factory axle shafts tend to weaken at taper points, which can lead to failure. The Ultimate Axle kit eliminates these weak spots by offering larger-diameter axle shafts with a more durable construction. Tests have shown that 300M axle shafts are twice as strong as OEM parts, ensuring reliability in both harsh off-road conditions and on-road driving.

Reinforced 300M axle shafts with 30 splines

Be prepared for the toughest trails—this axle kit transforms your Land Cruiser into a true off-road powerhouse.
Proudly made in the USA using only high-strength chromoly materials, the RCV Performance Ultimate CV Axle with 30 splines is the ideal upgrade to replace weak factory axles in your Toyota with a modern, heavy-duty design.
The factory axle setup uses 30 splines at the differential but tapers down to 27 splines at the CV joint—a common failure point. This kit eliminates that vulnerability by replacing the 27-spline CV joint with a 30-spline CV race made from premium 300M alloy.
Tests confirm that the Ultimate CV axles are twice as strong as OEM components and equally durable in both straight and extreme angles. Even when using oversized tires and high-output engines, these axles deliver unmatched reliability with minimal maintenance, providing smooth and quiet operation on any terrain.
The product is backed by RCV’s limited lifetime “no questions asked” warranty.
