NITRO CHROMOLY Birfields & Axles - Now available for Toyota applications!

Toyota Trucks & Landcruisers are well known for their strength & reliability all over the world. Out of the box they feature some pretty great drivetrain, but they do have their limits. The factory axles are 30 spline at the diff, but neck down to 27 spline at the birfield creating a failure point. Additionally the factory Birfield joints are not built to withstand the added stress of larger tires and heavy off road use. Nitro Gear & Axle has addressed this by offering a range of Heavy Duty Chromoly Birfield Joints & Axle Shafts.


-NITRO 30/30 Kits feature axles that have 30 splines at both ends, eliminating the factory neck-down. Fully compatible with factory or aftermarket carriers, lockers, & hubs.


-High strength Chromoly Material featuring State of the art machining, heat-treating and polishing processes for uniformity and ultimate in strength.


-Wide application range suiting most Toyota pickups, 4runners & Land Cruisers

I have a question...at what point do you "need" chromoly axles? I'm building a 84 pickup with a 4.3 v6, kinda getting my options for upgrades.

 

A lot of that depends on what size tire you are running, how much power you intend to make after the motor is swapped in (are you going to tune it at all?), and your driving style.

If you want, give us a call and we can talk to you about your options: 509 888 2953.

I also have a question; so these shafts let you leave the front ifs and just eliminate the cv joint? Are these knuckle things stronger than cv joints and or do you guys have a U-joint front ifs conversion? Are they bolt on? -Dan

 

Dan,

They are bolt on shafts, they eliminate the stock cv joint and shaft and use a much stronger birfield joint and chromoly shaft. If you need some pricing on them let me know.
