Nitro Toyota Land Cruiser 80 Series Replacement type Birfield Joints are designed to last. The 80 Series features a large, robust OEM CV joint called a Birfield. It is uncommon for these OEM joints to fail when running with other stock components; however, since 80 Series Land Cruisers are full-time 4WD the Birfields do wear constantly. In recent years weve seen off-Roaders flocking to these 80 series, installing large tires and taking them 4-wheeling only to break the strong stock Birfield joints. This is, more often than not, due to a joint that was already worn out and loose being overloaded, which leads to failure. Not everyone needs a Chromoly upgrade, these replacement Nitro Joints are a viable option for daily driven vehicles and they wont break the bank. These joints benefit from state of the art machining, heat-treating and polishing processes for uniformity and increased strength.
