Upgrade your Land Cruiser 80 or 105 Series front axle with the RCV Performance Ultimate 30/30 Spline CV Axle Seta proven solution to Toyotas most common front axle failure point. OEM 80 Series axles use a strong 30-spline differential side, but neck down to a coarse 24-spline CV, creating a weak link that often fails under heavy loads, big tires, or locked up trail use.

RCV eliminates this bottleneck by upgrading the CV joint to a 4340 chromoly 30-spline race, eliminating the neck down section entirely and dramatically increasing torsional strength. Tests prove these axles to be twice as strong as OEM, maintaining the same strength at full steering lock as they do in a straight line.

Built in the USA using premium chromoly materials, RCV Ultimate CV Axles deliver smoother power transfer, less vibration, and reliable performance both on-road and off-road.

Includes:

• Left & right upgraded CV axle shafts
• Two pre-greased high strength CV joints
• Hardware & boots
• Black oxide coating (standard)
• Optional nickel plating available for high corrosion environments
• Custom length inner shafts available (contact for pricing)

Tech Insight

The Land Cruiser 80 Series is legendarybut its front axle isnt. Toyotas 24-spline CV interface has always been a high stress weak point.

RCVs Ultimate CV design fixes it permanently:

• No more spline neck down full-strength 30-spline CV
• Twice the strength of OEM
• Smooth, low vibration torque delivery
• Strong at straight angles and at full steering lock
• Ideal for 3540 tires, heavy overland builds, and locked differentials

If you want your 80 or 105 to be as tough as its reputation, upgrading to RCV CV axles is one of the most important steps you can take.
